Carbon Fiber Plate Designs

0°/ 90° (balanced)

This is the most common layup for carbon fiber plates, suitable for most applications.  Balanced, 0°/90° plates offer excellent strength and stiffness in the axial and transverse directions. Our 0°/90° plates are evenly distributed, unidirectional carbon fiber prepreg, in the 0°, 90° orientation.

Quasi-isotropic (0°/90°/+45°/-45°)

Quasi-isotropic plates are designed for loading in multiple directions. This layup is ideal for torsional or off-axis loading. Our quasi plates are evenly distributed, unidirectional carbon fiber prepreg, in the 0°, 90°, +/-45° orientation.

Carbon Fiber Sheet FAQs

Drilling: Can I drill carbon fiber plates?

Yes, carbon fiber plates can be drilled. Here are some helpful tips:

  • Bit: Jobbers carbide drill bit for composites (brad-point)
  • Spindle speed: faster the better
  • Reinforce the backside to prevent blowout. This can be done with tape or by clamping the carbon fiber sheet to a sacrificial material.

Low CTE: What is the CTE of your carbon fiber plates?

Carbon fiber laminates have low CTE compared to standard metals. Laminate design can be modified to make zero/specific CTE’s. Reach out to our sales team for additional information.

Machining: Can carbon fiber plates be machined?

Yes, machining carbon fiber plates is relatively straightforward. See below for helpful tips.

  • Bit: solid carbide router bit for composites, diamond if available.
  • Spindle Speed: faster the better
  • Feed: based on thickness (proprietary)
  • Reinforce backside to prevent blowout. Can be done with tape or clamped to a sacrificial material.

Size: What is the largest size available for your carbon fiber plates?

The largest standard stock size available is 38″ x 96″. Custom sizes can be fabricated up to 48″ x 96″ x 5/8″ thick.

Temperature (TG): What temperature can your plates withstand?

Our stock, standard modulus plates have not verified the TG, but theoretical TG is estimated at ~200° F.

Temperature (TG): Is high temp material available?

We offer 350° cure, standard modulus, material as a custom solution. Higher temp material can be acquired but is on a per-part basis. Reach out to our sales team for additional information.
