Endless belts having driving surfaces comprising a high temperature flexible thermoplastic composite, which belts exhibit reduced noise, reduced frictional heat generation, improved dimensional stability and improved abrasion resistance compared to known belt constructions. 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. |
