The usage of Carbon Fiber sheets



Carbon Fiber composites have many unique properties. They are a good choice where light weight and high strength is required.

  • 30-40% lighter than aluminum
  • 5 times stronger than steel (at the same weight)
  • very low thermal expansion
  • good corrosion resistance
  • attractive appearance
  • vibration dampening properties


We have have been producing different composite products since 2014. During this time we have continuously developed and perfected our production methods. Our manufacturing facility is located in Estonia, Europe, and our main manufacturing technology is RTM. RTM (Resin Transform Molding) is a technology that enables to mass produce beautifully looking details on every side of the product while maintaining a consistently good quality.


What can be made from Erismet Carbon Fiber sheets?


Carbon Fiber sheets can be used in many applications. Here are some examples of Erismet™ composite sheets usage.



Engine valves for 2 stroke engines.  Thin 0.5mm Erismet™ composite sheets are used as reed valves for two-stroke engines.





Tools for industrial robots, Carbon Fiber sheets are a far superior material to aluminum and steel for making lightweight tools and robot parts. Carbon Fiber enables robots to make fast movements, lift more weight while using less energy and use smaller, less powerful and less expensive robots in return. Carbon Fiber composites greatly improve the productivity and lowers costs involved 


Machine parts, Carbon Fiber composites are becoming a common material for making production equipment. Carbon can decrease the mass of fast-moving parts, that in turn improve the efficiency of the machine due to shorter acceleration and braking time. Smaller moving mass also means smaller energy consumption. This leads to a machine with less power demand and can lead to a machine purchase at a lower price point. Another advantage of Carbon Fiber is the low thermal expansion and vibration dampening. These are extremely important properties for measuring tools and devices that work in a variable temperature environment. Vibration reduction is a property common required for 3D scanning technologies.



Drone parts, drones are mostly built from Carbon Fiber sheets and tubes. Carbon Fiber suits well for this application due to its light weight and strength. Sheets and tubes are also relatively easy to process due to their simple shapes so this eliminates the expensive mold making. Because weight is a critically important requirement for drones they are almost exclusively made from expensive, but light carbon fiber materials. Lightweight materials lead to precise movements, longer flight times and heavier carrying capability for cameras, cargo or other equipment.


Motorsport, different details for weight saving purposes. It is possible to manufacture details for motorbikes, cars, boats and other motorized and non-motorized vehicles.




Knives, Carbon Fiber sheets are used for making handmade knives with a sharp edge. These are usually used as letter-openers.




Knife handles, Carbon Fiber sheets are used as knife handles for handmade knives. They are lightweight, strong and visually appealing.



Jewelry and rings, due to Carbon Fiber's unique appearance it is used as items of decorations and is highly valued by designers.

Airplane parts, composites are becoming more and more common material for building airplane parts. This includes Carbon Fiber composites and composites made from Pure Carbon™ sheets and Core Carbon™ sandwiches.


Boat and other vessels, Erismet™ Core Carbon™ sandwiches are perfect usage for building walls, hatches, and floors. Erismet™ Pure Carbon™ sheets are used as protective and strengthening plates. Carbon Fiber usage allows building lighter and faster vessels.


How to process Carbon Fiber sheets?


Carbon Fiber sheets can be shaped and processed by common methods. They can be drilled, sawed, milled and sanded. Cutting blades and tools wear out quickly due to Carbon Fiber's abrasive properties. Carbon Fiber also creates fine dust particles, that need to be collected and disposed of to protect the workers and machinery. A half piece facemask is a must to protect the respiratory system.

For processing details with complex design, a CNC milling machine can be used. This allows cutting very precise shapes and can include small holes and indents.

Another cutting method is water jet cutting. This is a faster cutting method than CNC milling, but its precision and finish quality is lower. Water jet cutting also sets restrictions on the shape of the requested detail. Indents and engraving are also not possible.

Laser cutting is not a fitting cutting method because a good surface quality is very hard to achieve. 

Joining Carbon Fiber composites


Joining composite details is more complex than joining metal parts. Composites cannot be welded and threaded. 

Gluing, in many applications, using structural adhesives is a great bonding method. The adhesives that are being used are two component MMA (akylic) või epoxy resins


These glues will create a permanent strong join between components. The advantance of adhesives is a big surface area and an even load. Compared to welding and threading gluing does not create inner tension or bending. It is important to leave an overlap for gluing composites because glueing edges creates a much weaker bond.


Laminating, composites can easily be laminated. This process takes a lot of time, but can achieve high strength and an even load. Laminating is a good choice for large size composites (containers, reservoirs).


Bolds, screws and rivets, Carbon Fiber sheets can easily be joined with bolts, screws and rivets. This is one of the simplest and most common joining method. It’s only drawback are the stress points created around the connecting points.


Comparison to other materials




Carbon Fiber composites have an amazing strenght-to-weight ratio. This makes it an excellent choice for applications where weight saving is a must or where a stronger materials is needed, but weight cannot be increased. It is a superb alternative for replacing aluminum details.


Compared to thermoplastics and metals, Carbon Fiber composites are not remoldable. Once the composite has cured, it will keep its shape permanently. Carbon Fiber composites will bend a little at their thinnest points, but once you reach the critical limit, it will break.


Carbon Fiber composites have a vibration dampening properties. This makes it a great choice for using it for measuring devices and dampening impacts for sports equipment.


Another good feature of Carbon Fiber composite is a very low thermal expansion. This is another good property important for measuring devices where temperature ranges can change in extreme ranges.
