Abstract (en)

[origin: WO9828120A1] An injection molded reinforced structure (20) is prepared by providing an injection mold (40) having an injection molding cavity (42), and preparing a freestanding injection-mold insert (60) conforming to at least a portion of the shape of the injection molding cavity (42). The insert (60) preferably is formed of reinforcing fibers embedded in an insert thermoplastic resin matrix. The insert (60) is placed into the injection molding cavity (42), and an injection thermoplastic resin is injected into the injection molding cavity (42) and thence around the insert (60), thereby forming the injection molded reinforced composite structure (20).
