Abstract: In this thesis, polypropylene film was used as adhesive to prepare wood-plastic boards by stacking with the log board. By changing the surface of the wood panel, the amount of polypropylene film and the direction of the wood grain, a multilayer wood-plastic composite panel was successfully prepared by the hot pressing molding process, the impact properties, hardness, water absorption, aging test and other related tests were carried out to study the mechanical properties of materials under different variables. The results show that the...
