摘　　要：用乙烯-醋酸乙烯酯共聚物(EVA)对竹纤维(BF)/尼龙6(PA6)进行增韧改性,研究了EVA含量对BF增强PA6力学性能、热性能、形貌和加工性能的影响。研究表明,添加EVA可提高30%BF/PA6复合材料的韧性、熔体流动性和热稳定性。与BF相比较,EVA趋于提高PA6的结晶性能。添加8%EVA的30%BF/EVA/PA6复合材料可获得较高的冲击强度,其主要源于EVA产生的能量耗散以及BF、EVA和PA6之间存在较好的界面黏附和应力传递。Ethylene-vinyl acetate copolymer （EVA） was used to toughen the bamboo fiber （BF）/ nylon 6 （PA6） composites, and the effects of EVA content on the mechanical and thermal properties, morphology and processing ability of BF reinforced PA6 were studied. The results indicate that the addition of EVA results in the improvement of toughness, melt flow properties and thermal stability of the 30% BF/PA6 composite. Compared with BF, EVA tends to increase PA6 crystallization in the composites. The relative high impact strength can be obtained for the 30% BF/8% EVA/PA6 composites, which mainly results from the energy-absorption process caused by EVA, and better adhesion and stress transfer between BF, EVA and PA6.
