Abstract:
A process of producing a fiber reinforced composite comprising:immersing one or more continuous or short fibers selected from the group consisting of glass fiber, carbon fiber, silicon carbide fiber, aramid fiber, and metal fiber, in a uniform dispersion of polytetrafluoroethylene powder; wherein said dispersion comprises a dispersion medium;drying the fibers to remove the dispersion medium;compressing the dried fibers at a temperature of from about 327.degree. C. to about 350.degree. C. to produce a sintered shape; andplacing the sintered shape in an oxygen-free atmosphere and exposing the sintered shape to 200 kGy-20 MGy of an ionizing radiation while maintaining a temperature of from about 327.degree. C. to about 350.degree. C.
