用不同直径的杨木纤维填充聚乙烯基木塑复合材料，研究了木纤维直径和长径比等对木塑复合材料力学性能的影响。结果表明：随着直径的增加，复合材料的拉伸强度、断裂伸长率、弯曲性能、弯曲模量及冲击强度均呈先增加后减少的趋势；拉伸强度、断裂伸长率在直径为0．29 mm时出现最大值，弯曲强度、弯曲模量及冲击强度在直径为0．21 mm时出现最大值。

Polyethylene ( PE)-based composites were manufactured from the poplar wood fibers with various geometries to inves-tigate the effects of fiber diameter and length to diameter ratio on the mechanical properties of wood-plasticcomposites .The tensile strength, elongationat break, bending properties and impact strength are enhanced with the increaseof fiber diame-ter and then decreased as the fiber diameter further is increased .The tensile strength and elongation at break reach their maximum values at a fiber diameter of 0.29 mm.The bending strength, bending modulus and the impact strength have the maximum values when the fiber diameter is 0.21 mm.
