Abstract : The patent describes a high strength hot-press die composed of a conventional graphite inner die encased by a filament wound high strength graphite fiber. The high strength graphite fiber is filament wound on the conventional graphite inner die, and by the use of polymeric binders that will convert to carbon or graphite during bake out cycles, the fibers can be wrapped with sufficient tension to induce a compressional load into the inner die wall. This prestress condition will have to be overcome during actual pressing operations before tensional failure can occur in the die wall.
