A high tenacity fiber for reinforcing plastic composites, the fiber being selected from the group consisting of polyester, aliphatic polyamide, and combinations thereof. The fiber is treated with a composition comprising a vinyl chloride copolymer having a glass transition temperature of greater than about 60 DEG C., to enhance compatibility of the fiber and a resin matrix reinforced therewith. A process is provided to enhance fiber stiffness for cutting and comprises treating the fiber with the referenced composition, followed by heating the treated fiber to a temperature above the glass transition temperature to cause the copolymer to flow and form a film which substantially coats the fiber.
