金属纤维强化铝合金复合材料界面对其纵向拉伸性能的影响
The Effect of the Interface on Longitudinal Tensile Property of Aluminum Alloy Composite Strengthening with Metal Fibre
【摘要】 本文测定了复合材料界而层—纵向拉伸性能关系曲线.结果表明,当脆性层厚度大于10μm 时,开始起到强化效果;厚度为25μm 时强化达到峰值.用 SFM 考察了界面层的强化规律机理.
【Abstract】 The relationship curve of the interface-longitudinal tensile property is determined.It is shown that. The interfacial layer acts as a reinforcement when Fe2 Al5 layer is thicker than 10 μm.As Fe2 Al5 layer reaches a thickness of 25μm,the reinforcing effect of the interfacial layer will be strongest.The mechanism of the reinforcing effect has also been investigated.
