添加丙纶纤维及其改性处理对木塑复合材料性能的影响

就木塑纤维复合材料组分中添加丙纶纤维和对丙纶纤维进行改性预处理，改性剂的种类及改性剂的添加方式等引起材料物理力学性能和成网性能、模压性能的变化进行了研究。试验表明：添加丙纶纤维有助于改善材料的成网性能，使之成为具有良好模压性能的材料；对丙纶纤维进行改性的预处理可提高复合材料的物理力学性能；改性剂添加到木纤维中的工艺过程比对丙纶纤维进行预处理的工艺过程简单，并可以达到对丙纶纤维进行预处理的相同效果。

Effects of Adding Polypropylene Fiber and Modifying Polypropylene Fibers on Properties of Wood/Plastic Composite

The changes of physical-mechanical properties and molding performance of wood/plastic composite by adding polypropylene fiber, pre- treating polypropylene fiber with modifier, using different modifiers and different methods of adding modifier were studied in this paper. The experi- ment results showed that the molding performance of the composite was improved by adding polypropylene fiber; the physical-mechanical properties of the composite was enhanced by preformance polypropylene fiber; the technological process of adding modifier to wood fibers was more simple than that of pretreating polypropylene fiber, while achieving the same modifing effect.
