The heat resistance of CFRP, which uses epoxy resin, a typical thermosetting resin, is said to be about 200°C.

C/C composite is composite material made by carbonizing plastic into carbon through high-temperature firing and heat treatment of carbon fibers and plastic, and can be used at temperatures of over 2,000°C in a non-oxidizing atmosphere.

For this reason, CFRP is used in applications that are close to room temperature, such as golf shafts and aircraft parts, while C/C composite products are used in high temperature applications such as furnace parts and heat treatment jigs.
