Abstract
A process is disclosed for producing a semicrystalline polymer composite form which exhibits high strength and low electrical resistivity. Polyether-etherketone PEEK) powder and 4 to 10 volume percent a hard metal powder are blended and then compacted at room temperature to a relative green density greater than 60%. The resulting preform has an electrically conductive segregated network of metal particles throughout a PEEK matrix.
