  • Production of metal matrix composites reinforced with polymer fibers
    Patent number: 5085945
    Abstract: A method of manufacturing a metal matrix composite material containing high thermal stability polymer fibers, comprising the steps of: (1) providing high thermal stability polymer fibers; (2) providing a liquid-phase metal; (3) mixing the liquid-phase metal and the high thermal stability fibers; and (4) allowing the liquid-phase metal to solidify and form a metal matrix composite.
    Type: Grant

  • Production of metal matrix composites reinforced with polymer fibers
    Patent number: 5008158
    Abstract: Disclosed is a metal matrix composite comprising randomly oriented polymer fibers and a metal alloy surrounding the polymer fiber. The composite is formed by the method of manufacturing comprising the steps of: (1) providing polymer fibers; (2) providing a liquid-phase metal; (3) mixing the liquid-phase metal and the polymer fibers; and (4) allowing the liquid-phase metal to solidify and form a metal matrix composite. In a preferred embodiment, the polymer fibers are liquid crystal polymer fibers.
