摘要：This process and apparatus use at least two chopper units (24). The fiberchoppers may be laser beam choppers or existing standard chopper units. The processand apparatus for producing a fiber-reinforced molded composite comprises providing amoldable composition, a first fiber chopper providing chopped fibers (26) to theapparatus from a first direction, a second fiber chopper providing chopped fibers to theapparatus from a second direction, wherein the first direction is different from thesecond direction and molding the moldable composition and fibers in the apparatusunder heat and pressure to form the molded composite. One industrial application forthese choppers is compression molding of interior trim panels for automobile doors. Thechoppers spray chopped glass fiber strands (26) into a resin mixture(18). The glass and apolyol, isocyanate (-NCO) urethane resin mixture at the proper glass loading, distributionand pattern is fed to the mold (10).
