Carbon Fiber Sheet
Stock carbon fiber plates fabricated from multiple layers of high strength prepreg under high pressure moulding, in ten thicknesses from 0.5 mm to 5.0 mm at 500 x 400 mm.
What This Part Is and Why It Exists
Stock carbon fiber plates are fabricated with multiple layers of high strength carbon fiber prepreg using a high pressure moulding process. Every plate shares the same construction: the outer material is 2 x 2 twill carbon fiber prepreg and the inner material is 0/90 balanced unidirectional carbon fiber prepreg, finished matte on both faces.
That construction is the reason the plate behaves predictably. A twill skin gives the surface its appearance and handles the outer fibres, while the balanced unidirectional core carries load equally along both axes, so a bracket cut from the plate does not have a weak direction the designer did not expect.
Plates can be cut to size or machined to print by CNC milling or waterjet cutting, which means a stock sheet can become a finished part without a mould.
Four Reasons Buyers Specify This Part
Ten Thicknesses in Stock
0.5 mm through 5.0 mm in 0.5 mm steps, all at 500 x 400 mm, so the stiffness target can be met without a custom lay-up.
Balanced Core, Twill Skin
2 x 2 twill outer over a 0/90 balanced unidirectional core gives predictable properties in both axes.
Machined to Print
Cut to size or machined by CNC milling or waterjet, so a stock sheet becomes a finished bracket or plate.
No Tooling Required
Flat parts skip the mould entirely, which removes the largest fixed cost from a small programme.
Where This Part Is Used
- Drone centre plates, arm plates and camera mounts
- Robotic end effector plates and machine guards
- Instrument chassis panels and stiffening plates
- Sports and equipment components cut from flat stock
Buyers This Part Was Made For
- Design engineers needing predictable flat composite stock
- Machine shops cutting their own profiles
- UAV and robotics builders ordering repeat plate profiles
Three Failure Modes This Part Removes
Unknown lay-up
Plate bought on thickness alone can behave very differently in one axis; a stated 0/90 balanced core removes that surprise.
Tooling cost for flat parts
Paying for a mould to make a flat plate is money spent on nothing the geometry needs.
Inconsistent repeat orders
Ordering to a fixed part number keeps the second batch the same as the first.

How It Compares
| 3K twill plate over 0/90 UD core | Balanced properties in both axes with a finished twill surface; the default for structural flat parts |
| Fully woven plate | Simpler to make but less efficient; more fibre is doing nothing useful at the neutral axis |
| Aluminium plate | Easier to machine and cheaper per sheet, but far heavier for the same bending stiffness |
How to Specify and Order This Part
Choose thickness from the stiffness you need rather than the strength - flat composite parts almost always fail a deflection requirement before a strength one. Send a DXF for machined profiles and mark which edges are cosmetic, since exposed cut edges show the core.

How to Choose Carbon Fiber Plate Thickness
Stock plate runs from 0.5 mm to 5.0 mm in 0.5 mm steps. Choosing between them is a stiffness calculation, not a strength one - and the lay-up matters as much as the number.
