C/C (carbon fiber reinforced carbon) composites are made of carbon matrix reinforced with carbon fiber, and have high strength, high elasticity, high toughness, and ultra-high heat resistance, and can be used at temperatures above 1,000ºC.

C/SiC, also known as ceramic matrix composite (CMC), is a composite material with a ceramic matrix, and our CMC is reinforced with carbon fiber. It has higher strength and elasticity than C/C composite, and can be used in a wider variety of applications.
