摘要
通过比较ＳｉＣＰ／１１００Ａｌ和ＳｉＣＰ／７０７５Ａｌ两种复合材料的界面状况和弹性变形特点发现：两种复合材料界面结合状况的不同导致材料弹性模量相差较大，界面把载荷从基体传递到增强体是复合材料弹性变形阶段的重要强化机制，而且强化机制的作用发挥取决于基体与增强体之间的界面结合力。
The interfacial bonding and the elastic deformation of SiCP/1100Al and SiCP/7075Al composites were compared. The results indicate that the elastic moduli of the two kinds of composites are highly different due to the difference of those interfacial bonding, load transfer that occurs through interface between the matrix and the reinforcement is the important strengthening mechanism during the elastic deformation of the composites, and the strengthening effect of the mechanism depends on the interfacial bonding between the matrix and the reinforcement.
