Al 2 O 3 /Steel-epoxy层状复合材料的制备和性能
Source abstract
Abstract
采用环氧树脂胶黏剂作为粘结剂, 通过一种简单的模压方法, 在5 MPa压力下常温固化, 制备了一系列Al 2 O 3 /steel-epoxy层状复合陶瓷材料。结果显示, Al 2 O 3 /epoxy界面和steel/epoxy界面结合紧密。相比于氧化铝薄片, Al 2 O 3 /steel-epoxy层状复合陶瓷材料强度差别不大, 但具有更高的断裂韧性、冲击韧性和断裂吸收能。裂纹扩展分析认为层状复合材料断裂韧性和能量吸收的提高主要得益于裂纹尖端钝化和捕获、裂纹桥连、层间脱粘和steel-epoxy层的塑性变形等机制。
