Abstract
A plastic bearing and wear surface is disclosed which has low friction fibers protruding from its surface. The bearing is made by filling a plastic matrix with low friction fibers whose mechanical properties relate to those of the matrix in such a manner that when the matrix is machined, the matrix material will selectively be removed leaving some of the fibers imbedded in the matrix with their free ends protruding from and distributed over the machined surface.
