摘　　要：采用硅烷偶联剂KH550对氧化铝基体与金属丝网进行硅烷化处理,以环氧树脂为粘结剂制备了Al2O3/树脂/金属丝网层状复合材料,研究了偶联剂对层状复合材料层间粘结强度以及抗冲击性能的影响。实验结果表明:偶联剂的引入增强了树脂与氧化铝基体和金属丝网的界面结合,提高了层状复合材料的层间粘结强度;落锤冲击性能测试表明,通过硅烷化处理增强环氧树脂的粘结强度可以较大幅度提高陶瓷/树脂/金属丝网的抗冲击性能。Al2O3 slice and steel mesh treated by silane coupling agent KH550 were used as matrix and interlayer,and epoxy was used as binder,the Al2O3/ epoxy / steel mesh laminated composites were fabricated. The effects of KH550 on the bond strength and impact resistance of the laminated composites were investigated. The results indicate that the bond strength of the Al2O3/ epoxy and epoxy / steel interfaces is improved due to the application of KH550. The impact test shows that the impact resistance of the samples treated by KH550 is increased considerably.
