聚丙烯纤维对木/塑纤维复合材料性能影响的初步研究

A Preliminary Study on the Influence of Polypropylene Fiber on Properties of Wood/Plastic Fiber CompositeResearch Group of Wood/Plastic Fiber Composite

对木／塑纤维复合材料组分中添加聚丙烯纤维和对聚丙烯纤维进行预处理引起材料物理力学性能和模压性能的变化进行了研究。试验结果表明，添加聚丙烯纤维有助于改善材料的模压性能，但导致材料物理力学性能下降。对聚丙烯纤维进行预处理有助于提高复合材料物理力学性能。

This paper studied physical mechanical properties and molding performance of polypropylene (PP) fiber/wood fiber composite. Property changes caused by mixing both virgin PP fiber and pretreated PP fiber with wood fiber was analyzed. The test results showed that adding virgin PP fiber could improve molding performance of the composite, but made the physical mechanical properties reduced. Pretreating PP fiber proved to be a good way of increasing the physical mechanical properties of the composite.
