Abstract
A friction member for a frictional engagement device is provided in which weight is reduced, impact resistance is enhanced and sliding resistance is improved; and also provided is a method for producing the same. As a friction member () for a frictional engagement device, a friction member made of a carbon fiber/carbonaceous composite material is provided which is obtained by implementing a heat treatment on a precursor, the precursor comprising a matrix composed of a carbon binder and an additive and carbon fiber dispersed in the matrix, wherein a porosity of the friction member is 20-60%.
