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.
Shop Carbon Fiber Sheets
We stock a wide variety of carbon fiber sheets in our online shop, all available for direct shipping. Learn more about carbon fiber from our online resources. All Clearwater Composites parts are engineered and manufactured in our facility in Duluth, Minnesota.
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.
HOLIDAY CLOSURE: Our offices are closed December 23rd-January 1st. We will reopen January 2nd. Please note that orders received during this time will not be processed until we reopen.
