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.
