摘要：

Wood-plastic composite (WPC) is made of plastic matrix, wood fiber or particles, compatibilizers and other modifiers. WPC has the appearance and strength of wood but offers toughness similar to plastics making it a suitable material for practical applications. In this paper, the influence of temperature on the compressive properties of two kinds of WPC specimens with equal size was studied, and the relationship between load displacement and stress strain of WPC composites at four kinds of temperatures was analyzed. It was found that with the increase of temperature, the mechanical properties of WPC decreased and the ultimate displacement increased. The relationship between the ultimate stress, the ultimate strain, the ultimate displacement and the temperature is analyzed, and the performance of the specimens with two sizes is compared. The reduction factor for strength in the Eurocode 5 and other references are compared with this paper, so as to provide a reference for the research in related fields.
