The present invention is directed to fibers which are sized or coated on the surface with a polyamide-amic acid, an amide-imide polymer, an amide-imide copolymer or mixtures of these materials and to composites prepared from the sized fibers.

Polyamide-imide sized fibers

Polyamide-imide compositions, including amic acid precursors thereto, having in their molecules recurring units based on aromatic tri- and tetracarbonyl moieties joined by a bisphenoxyphenyl structure exhibit a desirable combination of chemical, mechanical and thermal properties and retention of these properties on exposure to elevated temperatures even after saturation with water.

A process for incorporating continuous graphite fiber reinforcement impregnated with polyamide-imide polymer onto injection molded polyamide-imide parts. These impregnated parts are useful as automotive parts such as push rods or rocker arms, and for aircraft parts such as fittings and secondary structural parts.

Continuous fiber inserts for injection molded parts

Novel fiber fabric laminates impregnated with polyamide-imide and polyamide-imide-phthalamide copolymers are disclosed. The laminates are useful as engineering materials for the replacement of metals.

Laminates

Flow properties of polyamide-imide polymers are improved by the addition of semi-crystalline nylons or amorphous polyamides. These polymers are useful as engineering resins, laminates, and molded objects.
