C/C composite,
C/SiC composite

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.


  • Light, high rigidity
  • Ultra-high heat-resistant properties (1,000ºC or more), chemical resistance
  • Low coefficient of linear expansion (dimensional stability, high-precision parts)
  • High thermal conductivity

  • Brake materials for automobiles, motorcycles, aircraft, etc.
  • Precision mechanical parts (weight reduction, heat-resistance characteristics, thermal-dimensional stability, chemical resistance)
  • General industrial parts (heat-resistant, light, high rigidity)
  • Springs, trays, fans, turbines, other components for ultra-high heat-resistant applications
  • Arms and hands for robots
  • Pantograph sliding plate
