Patent ID: 6926127

Claim:
A friction member of fiber-reinforced ceramic material, comprising: a core zone; at least one friction layer defining a plane; reinforcing fibers including short fibers and long fibers, said short fibers having a length of from 0.001 mm to 30 mm, said long fibers having a length of at least 50 mm, and said long fibers being present in a form selected from the group consisting of bundles, rods, laid fabrics, knitted fabrics and woven fabrics; at least 70% of said long fibers in said core zone being aligned parallel to said plane of said at least one friction layer, and said short fibers in said core zone having a substantially isotropic orientation; and said long fibers in said at least one friction layer having a proportion by weight of less than 10%, and said short fibers in said at least one friction layer having a proportion by weight of up to 35%.
