COMPOSITES USEFUL AS FENCE AND DECKING COMPONENTS AND METHODS FOR PRODUCING SAME

摘要

Composite fence and decking components (10), for example, rails, posts and planks, are provided which generally include a weatherable outer layer (12), a core layer (14) made of a thermal plastic polymeric composition and a wood component in an amount effective as a filler, and an inner layer (16) made of a thermal plastic material. The layers are configured so as to form a generally central hollow space (20). The components are light weight and inexpensive to manufacture. The components can be manufactured by using a single coextrusion process to produce a cylindrical form. The cylindrical form is passed through a reshaping die to (62) form a composite having a desired cross sectional form (64), for example, a composite with a substantially square or rectangular cross section.
