Friction Material

C/C as Friction Material

C/C composite is applicable to many areas of frictional material from “sliding” to “stopping” by controlling the frictional coefficient.

Characteristics of C/C as Sliding Material

1. Great Heat Resistance－Heat Resistance of 100% carbon
   They can be used in hot temperature where resin or metal can not be used.
   
   
2. Great Stability of the Size－The Coefficient of Thermal Expansion is 0～1(x10^-6℃)
   It prevents the deformation caused by frictional heat
   
   
3. Reduces Friction without Lubricant－Self-lubricant, the characterristics of carbon
   It can be used in those dry circumstances where lubricant can not be used.
   
   
4. Resistance against wear－Designs for each Frictional Circumstances
   The required resistance against wear can be achieved by designing the C/C composite for each circumstance.
   
   
5. Lightweight－Density is 1.7g/cm³
   It is so light that the weight is only 1/4 to 1/5 of iron (iron's density is 7.8g/cm³)
   
   
6. High Rigidity－Reinforced by carbon fiber
   It is 3 to 5 times stronger than ordinary carbon material because it uses carbon fiber as reinforcement.
