摘　　要：研究了褐腐真菌——洁丽香菇对不同纤维含量及添加不同抗菌防腐剂的HDPE基木粉及竹粉填充的复合材料的腐朽情况,观察了腐朽对材料质量及吸水性能的影响。结果表明,在洁丽香菇处理12周后,HDPE/木粉及HDPE/竹粉复合材料均出现了质量损失,且损失随材料中纤维含量的增加而增加,但抗菌防腐剂的加入,可明显提高木塑复合材料对腐朽真菌的抗性,减少其质量损失;同时,腐朽显著增加了材料的吸水性能,使其吸水率增加;木塑材料的吸水率还受纤维含量及吸水温度的影响。To reveal the effects of brown-rot fungi I_entinus lepideus on wood-plastic composites （ WPC ） based on HDPE, weight loss and water absorption of HDPE/wood and HDPE/bamboo composites with different fiber content and different fungicide were investigated. The results showed that, L. lepideus caused weight loss for both wood/HDPE and bamboo/HDPE composites after 12 weeks decay, and the weight loss increased with increasing wood or bamboo content. However, fungicide can obviously improve the decay resistance and then decreased the weight loss of WPC. Brown-rot fungi decay remarkably increased the water absorption of WPC. Besides, the water absorption of WPC was also affected by fiber content and water temperature.
