A wood-plastic composite member has made major advances in material performance, environment friendly and its production has become currently an important address of research concerned with engineering application of structures. Since the material and production equipment of the wood-plastic composite member are manly depend on the wood contents rate, a combination of compound, production order and so on, an investigation of production order, equipment and basic material characteristics of the unit member in order to used in structures and building is important. In this paper, these characteristics of highly filled extrusion wood-plastic composite member are deal with.
