摘要
本文在浸渗法制备复合材料的基础上,研究了氧化铝短纤维增强铝合金复合材料的界面。研究结果表明,在复合材料中,纤维与基体之间存在明显的界面层,合金元素通过适当的化学反应可改善浸润状况,有利于纤维与基体的结合。试样断口分析还表明,复合材料的界面结合状况良好,可传递足够的载荷到纤维上,发挥其增强作用。
In this paper, the interface of short alumina fiber reinforced aluminium alloy composite manufactured by the infiltration method was studied. The results indicate that there are obvious interface layers between the fiber and the matrix in the composites, and the alloy elements may improve the interface wettability by suitable chemical reaction between the fiber and the matrix. The analysis of the specimen fracture also indicates that the bonding between fiber and matrix is strong enough to transmit loading from matrix to fiber so as to play a reinforcing role of the fibers.
