1、 I 木塑复合材料的研究及其发展前景 摘 要 木塑复合材料（WPC）是国内外近年蓬勃兴起的一类新型复合材料，它是以木 纤维或植物纤维为主要组分，经过预处理使之与热塑性树脂或其它材料复合而成 的一种新型材料。这种复合材料具有能够充分发挥材料中各组分的优势，克服单 一材料的缺点，不仅改进材料的物理力学性能和加工性能，降低成本、扩大应用 范围，还提高了材料的附加值，木塑复合材料内含塑料，因而具有较好的弹性模 量。此外，由于内含纤维并经与塑料充分混合，因而具有与硬木相当的抗压、 抗弯曲等物理机械性能，并且其耐用性明显优于普通木质材料。表面硬度高， 一般是木材的 25 倍。所以，木塑复合材料具有优异的综

2、合性能及广阔的应用 前景。本文就该材料的目前国内外研究状况介绍了木塑复合材料的种类、生产工 艺，该材料的适用范围及其力学性能，以及国内外木塑复合材料制品的发展现状 和市场前景。 关键词：木塑复合材料, 性能, 发展前景 II Wood-plastic composites and their development prospects ABSTRACT Wood-plastic composites (WPC) is at home and abroad have mushroomed in recent years a new class of composite materials, it

3、 is kind of the thermoplastic resin or other materials compounded by wood fiber or fibers as the main component, after pretreatmentnew material. This composite material has to be able to give full play to the advantage of the various components of the material, to overcome the shortcomings of a sing

4、le material, not only to improve the physical and mechanical properties and processing properties of the materials, reduce costs, expand the range of applications, but also the added value of the materials, wood composite materials containing plastic, so they have a good elastic modulus. In addition

5、, because the mixing of containing fibers with plastic, and thus has considerable compressive strength and the hardwood, resistance to bending and other physical and mechanical properties and its durability is superior to ordinary wood materials. High surface hardness, is generally 2-5 times that of

6、 wood. Therefore, the wood-plastic composite material has excellent overall performance and broad application prospects. This article in respect of materials of the present research status of the species of wood-plastic composite materials, production processes, the scope of application of the material and its mechanical properties, as well as domestic and international wood-plastic composite material development status and market outlook.
