摘要 短碳纤维增强铝基复合材料可以经塑性变形加工成各种形状的零件,但塑性变形过程对材料的组织与性能有着重要影响。本工作用挤压浸渗法获得的Csf/Al复合材料为毛坯,通过挤压的方法,研究了变形温度、变形量等对材料组织与性能的影响。结果表明,一定量的塑性变形可以弥合浸渗不完全留下的微小空隙,并使纤维成方向性排列,复合材料的性能得到提高。但大变形会使纤维断裂,影响增强效果。变形温度越高,对复合材料性能越有利。

Abstract:Short fibre reinforcement Al-base composite can be manufactured various pieces by plastic working, but process of plastic deformation plays import role on micro-structure and properties of materials. In this paper, greens of Csf/Al composite were prepared by extrusion infiltration, and it was studied the effect of deformation temperature and deformation extent on micro-structure and properties of materials by extrusion. The results show that definite deformation could stitch micro-core resulting from imperfection infiltration and make short fibre array at a direction, so improve properties of the composite; however large deformation made short fibre break and deteriorated properties of the composite; properties of the composite became better and better with the rise of deformation temperature.
