Abstract
High strength thermoplastic resin/carbon fiber composites and methods of producing such composites are provided. The composites are comprised of carbon fibers, an amine-terminated poly(arylene sulfide) first resin component, and a second resin component selected from the group consisting of poly(arylene sulfides), polyolefins, polysulfones, polyether sulfones, polyetherimides, polyetherketones, polyethertherketones, polyetherketoneketones, liquid crystal polymers, and mixtures of such resins.
Claims35
A high strength thermoplastic resin/carbon fiber composite comprising:
- carbon fibers;
- an amine-terminated poly(arylene sulfide) first resin component;
- and
- a second resin component selected from the group consisting of poly(arylene sulfides), polyolefins, polysulfones, polyether sulfones, polyetherimides, polyetherketones, polyetheretherketones, polyetherketoneketones, liquid crystal polymers, and mixtures of such resins.
A method of producing a high strength thermoplastic resin/carbon fiber composite comprising the steps of:
- mixing carbon fibers with an amine-terminated poly(arylene sulfide) first resin component and a second resin component selected from the group consisting of poly(arylene sulfides), polyolefins, polysulfones, polyether sulfones, polyetherimides, polyetherketones, polyetheretherketones, polyetherketoneketones, liquid crystal polymers, and mixtures of such resins;
- and consolidating said mixture into a composite of carbon fibers in a resin matrix.
A method of producing a high strength thermoplastic resin/carbon fiber composite comprising the steps of:
- impregnating a continuous carbon fiber roving with a thermoplastic resin mixture comprised of an amine terminated poly(arylene sulfide) first resin component and a second resin component selected from the group consisting of poly(arylene sulfides), polyolefins, polysulfones, polyether sulfones, polyetherimides, polyetherketones, polyetheretherketones, polyetherketoneketones, liquid crystal polymers, and mixtures of such resins;
- and
- pulling said impregnated roving through a heated forming die whereby said impregnated roving is consolidated into a composite.
