Carlisle Brake & Friction's carbon carbon (C/C) material coefficient of thermal expansion (CTE) is similar to graphite, but less than that of stainless steel; therefore, minor changes to your process may be required to account for the difference. The competitive tensile strength of C/C composite material and the lower CTE, imparts greater compressive forces into the parts relative to traditional stainless steel clamping materials. An evaluation is recommended in such situations. Carlisle can help you design a test, create a shape and evaluate a change.
