Abstract
The present invention provides a wet friction member exhibiting excellent dynamic friction performance and a carbon fiber composite material for manufacturing the wet friction member. A carbon fiber composite materialof the present invention contains carbon fibersand a matrixjoining the carbon fiberswith each other, and the matrix has fine pores having diameters of 3.5 nm to 100 nm. Since the fine pores having diameters of a nanometer (nm) order is formed in the matrixof the carbon fiber composite material, the specific surface area of the carbon fiber composite materialis increased. As a result, a wet friction member made of the carbon fiber composite materialhas an improved dynamic friction performance.
