しつつ、耐摩耗性および耐クリープ性などの機械的特性
を改良しようとする試みがなされている。Sliding materials made of fluororesins such as polytetrafluoroethylene have excellent properties such as a low coefficient of surface friction, but they have low wear resistance and are susceptible to repeated contact with mating parts. As a result, the sliding material itself is prone to wear, roughness, and creep resistance is insufficient, so it is easy to deform when sliding for a long time while applying stress. It is difficult to form sliding materials. For this reason, Fi! l? ! Attempts have been made to improve mechanical properties such as abrasion resistance and creep resistance while maintaining the characteristics of fluororesins, such as a low coefficient and excellent chemical resistance and heat resistance.

Attempts have been made to improve the mechanical properties by blending relatively hard inorganic fibers such as 4 miscellaneous fibers. However, when fluororesin is blended with i-free fiber powder, it is obtained (
The abrasion resistance of snow moving materials improves, but when soft metals such as aluminum and brass are used as mating members for 1ffi moving materials, one snow moving material attacks the mating material during one movement, and this causes There was a problem in that the soft metal serving as the mating member was subject to significant wear. Furthermore, there is a problem in that when the opening portion between the active material and the mating member generates heat, the active material and the soft metal may seize.

００℃以上の温度で使用した場合摩耗しやすく、また熱
変形を生じやすいという問題点があった。In order to solve these problems, there have been two proposals for a 1-rich material composition in which a polyimide resin is added to a fluororesin. A rich material composition in which natural flaky graphite is added to a fluororesin is disclosed.A sliding material obtained from such a sliding material composition has a limit PV
However, polyimide resin is required (although oxybenzoyl polyester resin has insufficient chemical resistance, especially oxybenzoyl polyester resin). A problem with benzoyl polyester is that the ester bond within the molecule is easily hydrolyzed.If the oxybenzoyl polyester resin contained in the ribs is hydrolyzed, the oxybenzoyl polyester resin may be mixed into the active material. This results in loss of significance and increased swelling, deformation, and abrasion of active materials. On the other hand, polyarylether resin has excellent heat resistance and chemical resistance, and a sliding material composition in which a polyarylether resin is solely blended with a fluororesin is described in the US literature [Friction and Wear of PTFE and PEEK (WEAI)]. ?HA

This is not preferable because the wear resistance of the friction material at high temperatures decreases. On the other hand, if flaky graphite is used in a weight ratio of more than 40:60 with polyarylether resin, as a result, polyarylether Since the blending amount of the resin decreases, the wear resistance of the resulting sliding material decreases.
