ABSTRACT:
A crystalline polyamide 6 in a compounding extrusion process to make wood flour-polyolefin composite. The wood plastic composite pellet and can be post-blended with reinforced polyolefin pellets in an injection molding step to produce hybrid fibrous composites. The resulting compatibilization in the hybrid fibrous composites gives molded parts having enhanced mechanical properties at greatly reduced temperatures. There is wide variety of molded parts that can be made by varying the blend ratio of the wood plastic compounded product with or without and glass fiber reinforced pellets in the injection molding step.
