摘　　要：在1060系铝基体表面镀镍碳纤维作为增强体,进行真空热压扩散制备出碳纤维/铝复层材料。研究了制备工艺参数(加热温度、保温时间、压力大小)和碳纤维体积分数对碳纤维/铝复层材料的微观组织、界面结合、性能强度和断口形貌的影响。结果表明:碳纤维与铝基体界面结合良好,镀镍层与铝基体在碳纤维附近反应生成的AlNi阻止了铝基体与碳纤维之间生成脆性相AlC。随着碳纤维体积分数的提高,材料的抗弯强度先提高后降低。Carbon fibre-reinforced aluminium laminates was prepared by vacuum hot pressing diffusion with 1060 series aluminum as matrix and nickel plated carbon fiber as reinforcement in this paper.The effects of preparation parameters(heating temperature, holding time, pressure) and carbon fiber volume fraction on the microstructure, interfacial bonding, mechanical strength and fracture morphology of Carbon fibre-reinforced aluminium laminates were investigated. The results show that the interface between carbon fiber and aluminum matrix is well bonded, and the nickel coating and aluminum matrix react near the carbon fiber to form AlNi, which effectively prevents the formation of brittle phase AlC between aluminum matrix and carbon fiber. With the increase of carbon fiber volume fraction, the bending strength first increases and then decreases.
