Abstract
A sliding contact surface-forming material, and method of making the material are disclosed, the material having minimal swelling and excellent friction-proof and wear-proof characteristics when used in moist environments such as in water, and improved in the friction-proof and wear-proof characteristics under dry friction conditions such as in the open air, particularly under oscillation conditions for testing journal. The material includes a reinforcing base impregnated with a resol-type phenolic resin having polytetrafluoroethylene resin dispersed therein. The reinforcing base is composed of a woven fabric formed by using, as each of the warp and the weft, a ply yarn which is formed by paralleling at least two strands of a single twist yarn spun from fluorine-containing resin fiber and a single twist yarn spun from polyester fiber, and by twisting them in the direction opposite to the direction in which the single twist yarns were spun.
