Abstract
The present invention relates to a two-ply fibrous base material comprising a more porous primary layer having elastic and oil absorbent characteristics bonded to a less porous secondary layer having high temperature resistance and high strength characteristics. The two-ply fibrous base material, when impregnated with a suitable resin, provides a friction material exhibiting good friction and wear characteristics and is especially useful in high energy end use applications.
