摘要: 将短切玻璃纤维掺入木塑复合材料中,制备出具有增强效果的环保型木塑复合材料,探讨纤维的长度和含量对木塑复合材料的拉伸、弯曲以及冲击性能的影响。研究表明,随着玻璃纤维加入量的增加,木塑复合材料的拉伸、弯曲以及冲击性能明显提高;但材料的流动性能减弱,挤出胀大现象明显,发泡倍率降低。通过观察拉伸、弯曲和冲击断口SEM图片,表明玻璃纤维的拔出为木塑复合材料主要的破坏形式。

Abstract: Produce the enhancement of eco-friendly wood-plastic composites with chopped glass fibers mixed with wood-plastic composites. Researches show that with the increase of the content of glass fibers, the flow properties of the materials weak, the extrusion swell phenomenon is obvious and the foaming ratio decreases. Explore the degree of influence of tensile, flexural and impact properties with the addition of fiber length and content of the wood-plastic composites. The main failure mode of glass fiber reinforced wood-plastic composite materials is the glass fibers pull-out, the glass fibers breakage, the interfacial debonding, etc. By observing the interface of the tensile, bending and impact fracture, researches the main failure mode of glass fiber reinforced wood-plastic composite materials.

Key words: wood-plastic composites, foaming ratio, extrusion swelling, fiber length and content, fiber pull-out
