ABSTRACT OF THE DISCLOSURE This specification discloses reinforcing fibers coated on the surface with a sizing agent of polyamide amic acid, an amide-imide polymer, an amide-imide copolymer or mixtures of these materials (hereinafter collectively refered to as amide-imide polymers). The coated fibers are employed to prepare composites with amide-imide polymers as the matrix resin. The resulting composite has excellent toughness properties and enhanced thermal properties for extended use at tempera- tures in excess of 450°F. The sizing composition may be present on said fiber in an amount of 0.1 to 5% by weight based on the weight of the fiber. In certain embodiments the amide imide polymer comprises recurring units selected from the group consisting of (I) A units of: Image capable of undergoing imidization, wherein ? denotes isomerization, and (II) B units of: Image
