Scigrip adhesive experiment

30.01.2017
Scigrip adhesive experiment

Carbon.ee team tested our new adhesive that is now available in www.carbon.ee internet shop.

Adhesives are made in UK by company named Scigrip. This name, Scigrip has a meaning. SCI= Science and Grip= holding (what adhesives must have to do). Right now Scigrip is leader company in MMA adhesives. MMA means methylmethacrylate. MMAs are always 2 component liquid that cures to solid or flexible adhesives with various times. Solidness or flexibility and curing time depends on product.

 

We made several experiments, with different materials. We bonded steel, aluminum and carbon fiber pieces. After that we tried to break these joints with our Scania crane.

We lifted different concrete blocks weight from 600kg up to 3200kg. Even with so heavy weight it was really hard to break some bondings. Its really impressive to see D35mm steel bondings to hold 2000kg weight without breaking.

 

Test pieces:

D35mm steel to D35mm steel Breaks at 3200kg

D50mm steel to D60mm steel Holds 3200kg without no problem

Aluminium strip 140mm x 30mm to Aluminium strip 140mm x 30mm by side with adhesive length about 70mm x 30mm breaks at 2000kg. But only the metal himself, not bonding.

Carbon strip to carbon strip side by side holds 2000kg. Carbon did not break and adhesive also. Only problem was with weak fasteners. They got distorted.

Steel plate to steel plate with edges area 150x10mm Holds 3200kg without any problem.

Robotex 2016 in Estonia

One day, team named "Roadkill" turned to Carbon.ee and asked for a little help with carbon fiber. RoadKill had an idea, that they will take part in competition named Robotex 2016. The competition took place in Tallinn University of Technology. Robots played football and everybody had a great time. At the end of the day, team named Roadkill. By the end of the day team RoadKill got quite nice results:

1) Competition 2 vers. 2 they got the first place. 

2) Competition 1 vers. 1 they got the second and third place

Carbon.ee team was happy, that they could give contribute to team named Roadkill.

Article about our business in Swiss online magazine

Article about our business in Swiss online magazine

Original link: http://www.o-mag.ch/Specials/rubrik,645,Startup-helps-startups-and-others,news.htm

Startup helps startups and others

Three years ago Ben Einborn (26), a student in Tallinn Technical University, listened to a presentation of Defendec, an Estonian startup company of smart sensors. At Defendec they had a problem, that is very common for (Estonian) startups – no one wants to manufacture individual parts or small series. But Estonian startups can´t afford to order full wagon or even more of such parts from Chinese factories. So, Einborn founded his own company for serving startups. Together with his friend, software engineer Rinaldo Olberg (26), he started a small company to produce plastic parts for startups and small tech companies, who need only few pieces.

Ben Einborn, who studied product development in Tallinn Technical University and claimed masters degree, decided to find out, if it is possible to create molds that are easy to produce and much cheaper than metal molds. Discussing it with a friend, a metallic worker and mechanical student, Siim Katkosilt (26), they found that no company in Estonia offers silicone molding proffessionally. Even countries nearby had only very few companies doing this kind of things. They only found one firm in Finland. Of course, companies like BMW or Mercedes had their own technologies to do this kind of very exact molds, but they do not share their secrets behind exact molds from soft silicone.

Do not beleave Youtube videos

At the beginning, Einborn and Olberg thought that it should be quite easy to mold different details: just put the original part into liquid silicone and wait til it is hardened. But that’s not working, at least for hardware companies which need very accurate details. It is not suitable to act as hundreds of Youtube videos suggest, how to repair a broken toy with silicone molds of materials you can buy from general engineering stores.

The first experience the three young engineers made, was that they need to do molding in a vacuum environment and use special professional silicone. Then they learned that it is very important how they fill the molds and how they break molds apart after. The most important thing to start a company was of course the market. You may order tens of thousands or even millions of individual parts from factories, but if you ask for 10 or 20 or even 100 or 1000 parts, no-one wants to fill your order at a reasonable price.

3D printing – competitor at very small amounts

There is a market for unique details manufacturing – 3D printing. Many companies in Estonia started 3D printer services to produce unique parts. But it is expensive and slow. A single detail print-out may need several hours, and if you order 10 pieces or more, it may take days or weeks to print. And the price - of course - is even higher. Silicone molds cost between 50 to 100 euros. For comparison – metal molds may cost hundreds or even thousands of times more.

It all started under the roof of industrial loft

At first, Erismet moved to an old soviet-time hangar near Ülemiste junction – the room was fitted with some 3D printers, a self-made vacuum chamber and a hand press. Einborn and Olberg started the company in august 2010 to produce small series or even single parts with silicone mold technology. There was no need of fancy office and suited officials, startup people respected the company with hand-made units and small workroom somewhere in the industrial loft.

But the first customers were actually not startups. The very first client was a logistics company who needed pedestals for barcode readers. They bought 5 to 6 pieces of them. First mold failed several times, but at last it was exact and strong. Other things asked were bodies of electronic sensors for Estonian military company and first big order came from famous Estonian shipping company Tallink. They wanted 6000 copies of a plastic detail for passenger ferry cabins and this very quickly. The Shipping company had no time to wait for metal molds. So, Einborn and Olberg mobilised all their family members and friends to do molding works with hundreds of molds. It took only eight days and Tallink was satisfied.

Another order was from a shipping company, too. They ordered parts for fixing electronic price plates to sales counters. This was one of the biggest order – 10 000 pieces - and scratched the limit of silicone molding, as you need a lot of silicone molds – about 200 to produce such an amount of parts. But it´s still cheaper than ordering metal molds and producing plastic details the traditional industrial way.

Plastic is not the limit

Einborn learned that they cannot only manufacture plastic parts with silicone molds. You also may produce soaps, concrete things or candles. One client, for isntance, asked molds for special soaps, and they did a 3-in-one mold for soap manufacturing. It is possible to do details from any materials, only restriction is that this material is not heating the silicone higher than 294 degrees celsius.

Today clients come with a CAD file of prototype and ask for 5 or 6 pieces of it physically made of plastic or other materials. The company usually prints the CAD file out with a 3D printer. With the printout they prepare a silicone mold. Therefore the mold is placed to a vacuum chamber. It is barrel with 0,5 meter diameter and special tubes for plastic and air addition. All the magic is to design pipes and cuts correctly for perfect filling the mold. Erismet designed this chamber from scratch.

The next big thing – carbon fiber

Last year Erismet moved to a larger premises to be ready for quick expansion. Because this time they are also focusing on another production – on carbon fiber plates. Marketing research showed that in Estonia and surroundings are only a few providers of carbon fiber plates or curved carbon fiber parts. Erismet engineers now have two interesting devices in the new workroom which look like giant juicers. Actually it is a carbon fiber press. All devices they have projected and done by themselves. Carbon fiber is very popular. The strong material is often needed in car and aerospace industry. Einborn keeps company secrets of new big clients, who need carbon fiber details. But some of them they can disclose.

„Drone manufacturing is very popular,“ Einborn says, „we can do drone parts and cut them out from plate. Later we can do tubes and special forms if needed.“ The plates they do vary from 450 x 450 mm to 500 x 700 mm. Carbon fiber consists of carbon fiber layers (up to 10 layers) and pressurized resin. Carbon fiber press is manual, because it´s more secure and cheaper. Carbon fiber press is the best method to produce carbon fiber parts the industrial way – all parts look exactly the same and the quality does not vary as you know for example from boat builders – when workers paint different layers by hand.

Conquer the world via e-store

Meanwhile German companies are among the purchasers of their products. Salesman Madis Kerna (26) started to sale products on company e-store Carbon.ee and they have sold to different countries on eBay as well. Even australians are very interested of carbon fiber details from Estonia. They have bought several times and are satisfied. So, why they order from Estonia? Kerna beleives that there are two main reasns: carbon fiber is cheaper and much stronger. There are some Canadian companies which say that it´s more like car industry quality. The company orders chemicals and materials from the same factories as Lamborghini and McLaren. The carbon fiber is from the same source where Airbus orders. Erismet shares room with another Estonian company – Ropeye, who produces rope fasteners for sailing yachts. They need very secure and strong parts and some tests proved, that manufactured plates of carbon fiber are strong enough for fasteners.

There is always a product. Erismet tries to fill this gap.

Carbon Fiber- All Patterns Explained

Carbon Fiber- All Patterns Explained

You are searching good looking carbon fiber sheets or you want to make some specific details?

And then you see out there many sellers. Everyone has different patterns... Sounds familiar? Lets have a closer look.

 

1x1 Carbon Fiber Pattern

This pattern reminds math notebook. Is also called plain weave pattern. Its over-under pattern is the pretty standard pattern. Not the strongest of weave but is solid and shouldn't let you down.  Easiest to handle without making the fibers on the ends too messed up. Other weaves fall part incredibly fast, but make up for this is some cool patterns and more strength in the direction of the weave. It is the tightest weave.

1x1 Plain Pattern

2x2 Twill Weave Carbon Fiber Pattern 

This pattern looks more  modern than 1x1 plain pattern. Got quite unique look. It represents the diagonals that are synchronized. Is braid over-over-under-under. Most popular pattern that many carbon fiber factories use to make details.  2x2 Twill is mostly used in imitations also. This pattern is elastic and it is good for use with complex shapes because its weave is looser.

4 Harness-Satin Carbon Fiber Pattern

This pattern reminds bricks. It looks like wall and it has a point. These are supposedly some of the stronger structural weaves. 4HS= 4 over 1

4 Harness-Satin Pattern

5 Harness-Satin Carbon Fiber Pattern

Brother to 4HS.  A Harness-Satin patterns almost always has more weaves per inch than a plain or twill weave (defined as “pics”). Has a higher pic count and it will hold together bit better than a twill weave when handled carefully. 5HS= 5 over 1  

5 Harness-Satin Pattern
5 Harness-Satin Pattern
 

8 Harness-Satin Carbon Fiber Pattern

Relative to 5HS. Reminds long rice grains but it looks simple and awesome. It is also pretty plain to see that the weave will fall apart in your hands if not handled well. If you have very complex curves, an 8 Harness-Satin is the best choice. 8HS= 8 over 1

4x4 Twill Weave Carbon Fiber Pattern

Quite fancy pattern, but not the fanciest. Pattern reminds arrows heads or tractor traces. Is not so prevalent pattern in the carbon fiber sheet market. 4X4 twill will bend around curves better than a 2X2 twill weave. 

4x4 Twill Pattern

Unidirectional Carbon Fiber Pattern

Well... This reminds a brunette girl hair. But can we say that this is a weave? Depends on viewer artistic talent. Is used in applications where almost all of the forces exerted on the object come form one axis (up and down, left and right, front and rear). 

Unidirectional Pattern

These were the most common patterns in the carbon fiber world.

Different weaves can either give varying amounts of strength and looks. They distribute forces in multiple directions differently and can often change strength in the way they are laid and molded as just for a different weave. The looser the fabric, the more likely the fabric will fray at the ends and create spaces in the fabric when bent around complex curves. But a loose fabric will fit around complex curves much better than a tighter weave fabric. Now, lest have a look unusual patterns...

 

Triaxial Balanced Carbon Fiber Pattern

With first look it reminds 2x2 Twill weave, but actually it is not the same pattern. The number of fiber directions from two to three, and changing the orientation of the fibers from orthogonal to 60 degrees increases the damage tolerance and also improves energy absorption. The weaving construction is ‘two over, two under’, alternating over and under the axial yarns. Applications are for composite reinforcement in aerospace, engineering, sports equipment and automotive racing.

Prepreg Triaxial Carbon Fiber Pattern

If we look closer it reminds beehive. Potential applications for this triaxial pattern include diaphragm transducers such as pressure sensors, microphones, loudspeakers, stethoscopes and electromagnetic devices such as antenna reflectors.

Trixtial Patterns

There are many trixtial patterns but the point it that you will get the understanding why it can be good for you. 
* Triaxial weaving is part of the traditional craft of basketry. Its use has been dated back to around 5,700 BC in Japan. 
* Triaxial weaving produces material which is structurally superior to many sorts of rectangular weaving. Since the structural elements run in three directions, the resulting fabric is much more resistant to shearing forces and doesn't easily crimp. 
* Triaxial fabrics often have good strain resistance, planar shear resistance, tear resistance, abrasion resistance and bursting resistance. 
* What applications are suitable for using triaxial techniques? 
The main selling points of triaxial weaving are: 1) Light weight; 2) Low material cost; 3) Isotropy; 4) Shear-resistance. 
* Trixtial patterns are not very common, so it is also harder to get one. 

Lets look now on bit crazier patterns...

 

1K x 3K Plain Weave Carbon Fiber Pattern

Unique plain weave. With a 3K warp and a 1K fill its loose weave is highly formable and wets out easily. Is is used to add selective directional reinforcement to applications without adding considerable weight.

1K x 3K Weave pattern

A Jacquard Weave Carbon Fiber Pattern

If you have been to Estonian Song Festival then you probably have seen historic folk clothing. You can see in Estonian Song Festival the same pattern in wool skirts, belts and men waistcoat. This pattern is actually mostly the same as the 1x1 Plain weave.

D Jacquard Weave Carbon Fiber Pattern

If you are producing carbon fiber violins or cellos then this pattern can be just for you. Until you use it just for the cosmetic looks.

Aquarius Carbon Fiber Pattern

Well in this point we can have a question in our heads that how far can we go with patterns? This pattern is suitable for Russian carbon fiber accordion cosmetic looks.

Constellation Carbon Fiber Pattern

It looks like this pattern has used the unidirectional carbon fiber (black squares) but not quite sure. It can be quite good pattern because it looks like it is trixtial pattern.

Galaxy Carbon Fiber Pattern

This pattern reminds videos that depict LSD effect. Why this pattern can be better than others? Well... here we can talk more about art and cup of teas. Its more just to cosmetic looks.

Rook Carbon Fiber Pattern

The rook, named after a chess piece, reminds a chessboard depending on the angle of light you’re looking at. We can see either the chessboard or a larger diamond grid with a smaller square inside of each other. When you see the grid, it gives off a very three-dimensional appearance, as if the blocks are almost popping out of the fabric. 

Rook Pattern

Atomic Carbon Fiber Pattern

The atomic pattern is really defined diamonds within diamonds within diamonds. Mostly like to see this one laminated with believing it would really pop between the differences in contrast with light shifts. 

Atomic Pattern

Grandmaster Carbon Fiber Pattern

From an aesthetic appearance, the Grandmaster is quite huge, but also the one that’s not exactly new or unique. The best way to describe the Grandmaster is by picturing a normal plain weave and zooming it in. Essentially, it’s a regular piece of carbon fiber with a really large weave, making for an extraordinary look. The dry fabric is fairly stiff so it will be a little harder to work with, but the effort should be worth the results. 

Grandmaster Pattern

Wasp Carbon Fiber Pattern

The Wasp pattern is like taking a mixture of twill and plain weave, and then putting a honeycomb pattern within those. The pattern comes off as almost a reptile skin which would be an interesting look for the application you’re using it on.

Wasp Pattern

Roswell Carbon Fiber Pattern

At certain angles this patterns almost looks like little spaceships… or hamburgers, which fits the Roswell name well. There is a mixture of different shapes, patterns and angles, giving an extremely unique and different look that is sure to stand out amongst the crowd.

Roswell Pattern

Labyrinth Carbon Fiber Pattern

The labyrinth is definitely the “funkiest” off the patterns with an almost chaotic pattern that has definition. This pattern seems to be the lightest fabric of the bunch, most likely making it the easiest to work with when conforming to curves.

Labyrinth Pattern

Crazy, odd and fancy patterns.

Well actually there are much more and more patterns out there. Our imagination is the limit. But why there are so many patterns in carbon fiber world? If we look around nowadays then we see fashion everywhere. Can we say that carbon fiber cloth manufacturers have gone crazy and are part of fop? So and so. If you start an new carbon fiber cloth factory, then you need costumers. You will have to have: 
1) Classic patterns. (what is standard) 
2) "Something more" patterns. (which can add value) 
3) "Wow" effect patterns. (something that world has not seen before) 
Otherwise your factory will not survive.  

Mostly these crazy, odd, fancy, sexy and "Wow" effect patterns are directed to innovators. 

 

Carbon Fiber- What is K?

Carbon Fiber- What is K?

Many buyers are scratching their head when they see in advertisement "3K" or "12K". What that means?

Lets have a closer look... 

 


 

About K

Have you heard about 3K and 12K topics with carbon fiber?  I think that you do. In case if you did not know then there are also 1K, 2K, 3K, 6K... To understand it we have to look deeper how carbon fiber plates are made.

Fabric

Carbon fiber is frequently supplied in the form of a continuous tow wound onto a reel. The tow is a bundle of thousands of continuous individual carbon filaments held together and protected by an organic coating.

Carbon Fiber fabric

Carbon Fiber tows

First, let`s understand the main point. 12K means there are 12,000 filaments per "tow" and 3K means there are 3000. The tow can be conveniently unwound from the reel for use. Each carbon filament in the tow is a continuous cylinder with a diameter of 5–8 micrometers and consists almost exclusively of carbon.

1K Carbon Fiber

1K carbon fiber:  Is a very rare fiber.  It is lighter than other fibers and provides a more supple ride than a larger weave. 1k fiber is top of the bill, but the case is its expensive and low modules fibers more for finishing surface and most compagnys cannot even calc the stress inside a weave. 22,568 ft/lbs, 66 g/1000m

2K Carbon Fiber

2K carbon fiber: Is the rarest carbon fiber available on the market. It is produced by no more than 2 carbon manufacturers in the  world. This gives the plate perfect stiffness, low weight, and great vertical compliance (comfort). It is also very expensive. 

Carbon.ee´s Carbon Fiber sheet

3K Carbon Fiber

3K carbon fiber: The most popular, most common carbon fiber. It gives to the plate classic carbon fiber look. 3K is the workhorse of carbon fiber.  It's light, relatively stiff and easy to get and make. 3K got higher elongation before failure and ultimate strength than 6K, 9K or 12K. Because 3K is a smaller bundle of fibers, thinner fabric can be woven than with 12k, or thinner tubing can be filament wound, but if the fiber is the same grade, stiffness and strength are not affected by tow size. It is used in Aviation, industrial field, architecture, sporting, recreation goods. 7,523 ft/lbs, 198 g/1000m

6K Carbon Fiber

6K carbon fiber: It is easier to work with 6K & 9K than 12K. It wets out easier and it drapes better. It is used in Aerospace, building reinforcement, car tuning .7,523 ft/lbs, 396 g/1000m

12K Carbon Fiber

12K carbon fiber: Some factories might use a 12K to keep the cost down, because fabric is cheaper than the other K-s. 12K is easier to make hence you only need 1 layers in stead of 3 layers so less work too and cheaper.  Some say that they do not like 12K because its pattern looks big and robust. Generally the larger the weave, the stiffer it is, but is also heavier. It has higher tensile strength. It is not suitable for certain parts of the bicecycle.  It is used from military to industrial robotics to scientific equipment. A layer or two would probably be used in critical high-stress areas like the BB area, HT area and the chainstays. 1,862 ft/lbs, 800 g/1000m

24K & 48K Carbon Fiber

24K & 48K carbon fiber: It is used on manufacturing of filters, heat protection, sewing of working clothes, manufacturing of soft furniture and mattresses.

Unidirectional Carbon Fiber

Unidirectional carbon fiber: This carbon has fibers that run the same way rather than being woven together.  Is type of carbon fiber that can be used to create a carbon bicycles. It is used also in  airplane wing spars where is needed strength and stiffness running along the lenght of the wing.
