ABSTRACT:
A composite material having a coated fiber structure dispersed in a polyester matrix. The coating is a block copolymer having an elastomer block bonded to an ester block. The coating provides a flexible barrier between the fiber structure and the polyester matrix which results in a strong fiber reinforced composite having better crack resistance and improved toughness. The composite is particularly suited for use as a molding compound for use in the production of automotive body panels and structural components, aircraft components, sporting goods, housings for electrical and various other consumer goods, etc.
