Study on the effect of ratio polypropylene, chemical coupling agent, wood flour on the tensile strength and flexural strength of wood plastic composite
Keywords:
tensile strength, flexural strength,, composition ratio, wood plastic compositAbstract
The quality of wood plastic composite material is shown through factors such as tensile strength, flexural strength,... These factors have intimate relationships with technological parameters of composition ratio. The study determines the optimization of composition ratio parameters in the production process allowing to reduced price of
production and improve the quality of the product. The results were shown that the value of tensile strength and flexural strength were depended on the rate of composition of polypropylen, chemical coupling agent and wood fiber. A quadratic equation was established and solved to determine the optimization of rate of compositions. Polypropylen is 50.4%; Chemical coupling agents is 4.04%; Wood flour is 45.56% with these compositions, the wood plastic composit will has the best results of the tensile strength and flexural strength
