度の低下し生じる。For this reason, in order to use it as a sliding material, attempts have been made to lower the coefficient of friction by including a resin having a low coefficient of friction, such as polytetrafluoroethylene resin (PTFE). However, on the other hand, as the coefficient of friction decreases, wear resistance and mechanical strength decrease.

Carbon fiber (abbreviated as AN type) is made of polytetrafluoroethylene resin (PT
Attempts have also been made to incorporate it together with a resin having a low coefficient of friction such as FB), and high mechanical strength has been obtained. However, due to the high mechanical strength, damage to the mating material and reduction in wear resistance occur. Another drawback was that the molding shrinkage rate was highly anisotropic and the dimensional stability of the molded product was poor.
