以高密度聚乙烯（ HDPE）、马来酸酐接枝聚乙烯（ MAPE）、竹浆纤维、竹造纸剩余物竹屑、白泥为试验原料，制造竹塑复合材料。采用基本断裂功（EWF）方法对竹屑／HDPE、白泥／竹屑／HDPE和竹浆纤维／竹屑／HDPE 3种复合材料的冲击韧性进行了研究，比较了不同质量分数的竹屑、白泥、竹浆纤维对复合材料各性能参数的影响。结果表明：复合材料的比基本断裂功（ we ）随着竹屑和白泥的增加逐渐下降，随着竹浆纤维的增加显著提高；竹屑和竹浆纤维的质量分数对竹塑复合材料的比非基本断裂功（βwp ）影响较小。

Bamboo plastic composites were manufactured by high density polyethylene (HDPE), MAH-polyethylene (MAPE), bamboo pulp fiber, bamboo residue and white-mud from bamboo paper making industry.We studied impact toughness char-acterization of bamboo residue/HDPE, white-mud/bamboo residue/HDPE and bamboo pulp fiber/bamboo residue/HDPE composites by essential work of fracture ( EWF) methodology, and compared performance parameters of composites with different contents of bamboo residue, white-mud and bamboo pulp fiber.The specific essential work of fracture ( we ) of composite was decreased with the increasing of white-mud and bamboo residue, but significantly increased with the increas-ing of bamboo pulp fiber.The contents of bamboo residue and bamboo pulp fiber had little effect on the specific nonessen-tial work of fracture (βwp ) .
