Through the tensile, compression, bending, nail holding force, hardness, impact and water absorption of the wood-plastic composite material, the mechanical and physical properties of the material were measured, which provided the basis for the utilization and further research of the material. On the basis of the experimental analysis, it is believed that the wood-plastic composite material should further expand its use and replace other existing materials, such as wood, and also need to improve its flexural strength and fracture toughness and reduce its density. It starts with strengthening the bonding force between the substrate and the filler, increasing the fiber content of the filler or changing its shape to increase the slenderness ratio of the filler, reducing the aggregation of the filler, and using foaming technology.
WPC products can be maintenance-free. Wood generally needs maintenance or painting within a year. In the long run, the maintenance cost of plastic wood is far lower than that of wood products. In the same case of wood plastic, less can win more. Let me make an analogy. Generally, the plastic wood floor is used as an outdoor floor. When wood is used, wood with a thickness of about 45MM is required. For plastic wood, only 25MM thick material is needed, and its strength exceeds 45MM preservative wood. In other words, if the wood used is 1 cubic meter, then the plastic wood only needs about 0.5 cubic meters.
