LONG-TERM OUTDOOR EXPOSURE RESISTANT OVERMOLDED POLYESTER COMPOSITE STRUCTURES AND PROCESSES FOR THEIR PREPARATION.

摘要

The present invention relates to the field of ultraviolet light stabilized overmolded composite structures comprising polyester compositions, and processes for their preparation. The disclosed overmolded composite structures comprise i) a first component having a least a portion of its surface made of a surface resin composition and comprising a fibrous material being impregnated with a matrix resin composition, and ii) a second component comprising an overmolding resin composition, wherein the second component is adhered to the first component over at least a portion of the surface of the first component, and wherein the surface resin composition is selected from polyester compositions comprising a) one or more polyester resins, and b) at least three UV stabilizers.
