摘　　要：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/HDPE3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 characterization 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 increasing of bamboo pulp fiber. The contents of bamboo residue and bamboo pulp fiber had little effect on the specific nonessential work of fracture（ βwp）.
