Wood-plastic composite (WPC) is a kind of composite material that is made of plastic and wood fiber or wood powder. Because it is mothproof, is resistant to corrosion, and has plasticity, among other advantages, it has been researched and used increasingly in building materials. The flexural property of WPC is an important subject in evaluating its mechanical properties. In this paper, wood-plastic raw materials and processing technology are introduced; the internal and external factors of WPC which affect the flexural properties are analyzed; the different ways of enhancing the bending capacity, including the surface pretreatment, addition of different modifiers (compatibility agent and coupling agent) etc. are summarized; and the methods of operation and strengthening effect are analyzed. This work provides a reference for further research in related fields.
木塑复合材料(WPC)是一种由塑料与木纤维或木粉制成的复合材料。因其具有防虫、耐腐蚀以及可塑性等诸多优点,在建筑材料领域的研究与应用日益广泛。木塑复合材料的弯曲性能是评估其力学性能的一个重要课题。本文介绍了木塑原材料及加工工艺,分析了影响木塑复合材料弯曲性能的内外部因素,总结了增强弯曲性能的不同方法,包括表面预处理、添加不同改性剂(相容剂和偶联剂)等,并分析了操作方法及增强效果。这项工作为相关领域的进一步研究提供了参考。
