Endless belts having driving surfaces comprising a high temperature flexible thermoplastic composite. More particularly, an endless toothed belt having a high temperature-, abrasion- and noise resistant cover element, and which comprises from about 60 percent to about 100 percent by weight of the composite of a high temperature flexible thermoplastic material and from about 0 percent to about 40 percent by weight of the composite of a frictional modifier system, and methods for constructing such belts. Such belts include elastomeric body portions which may preferably be formed from suitable polyurethane materials.

[ What is claimed is:] [1.]1. An endless belt having a driving surface portion, and characterized in that said driving surface portion comprises a high temperature flexible thermoplastic composite, said high temperature flexible thermoplastic composite having a melting point higher than about 150.degree. C., and comprising from about 60 percent to about 100 percent by weight based on the total weight of said composite of a high temperature flexible thermoplastic material, and from about 0 percent to about 40 percent by weight based on the total weight of the composite of a frictional modifier system.
