Wood-plastic composite material, as a kind of environmentally friendly composite material, mainly uses thermoplastic polymers such as polyethylene, polypropylene and polyvinyl chloride to replace the usual resin adhesives. And other waste plant fibers are mixed into new wood materials, which are then obtained by extrusion, molding, and injection molding. Compared with wood, wood-plastic composite material has a series of excellent properties, and it is also a green and environmentally friendly, renewable material, which is easy to prepare into various profiles. In recent years, it has developed rapidly internationally and is widely used in interior decoration, automobile interior decoration, outdoor garden landscape and other fields. Due to the inherent creep characteristics of thermoplastic polymer composites and the shortcomings of wood-plastic fragility under high wood fiber content, the application of existing wood-plastic composites is limited to indoor and outdoor decoration, garden landscape materials with anti-corrosion and waterproof functions, etc. Non-load-bearing decorative materials, not suitable for load-bearing structural materials that require high rigidity and toughness.
