摘　　要：重点比较了正硅酸乙酯(TEOS)、聚乙烯醇缩丁醛(PVB)和丁腈橡胶(NBR)三种增韧剂对酚醛树脂基复合材料拉伸性能、冲击韧性、弯曲性能等力学性能的影响,并基于疏散平台制品实际需求,考察了增韧剂对复合材料热值的影响,最后对各增韧剂的增韧机理进行分析。研究结果表明:三种增韧剂对酚醛树脂基复合材料均有显著的增韧效果,其增韧效果与添加量相关且增韧机理各不相同。This paper focuses on the comparison of the effects of three kinds of tougheners,namely,silicic acid(TEOS),polyvinyl butyral(PVB)and nitrile rubber(NBR),on the tensile properties,impact toughness,bending properties and other mechanical properties of phenolic resin matrix composites.Based on the actual needs of evacuation platform products,the effects of tougheners on the thermal value of composites are investigated.Finally,the possible toughening mechanisms of each toughener are analyzed.The results show that the three kinds of toughening agents have significant toughening effects on phenolic resin matrix composites,and their toughening effects are related to the amount of addition and their toughening mechanisms are different.
