Effect of Surface Mechanical Attrition Treatment (SMAT) on the Tensile Performance of Fibre Reinforced Aluminium Laminates
-
摘要: 表面机械研磨(SMAT)技术是在短时间内通过振动发生器驱动大量硬度较大的小球以随机方向撞击金属材料,使得材料晶粒尤其是表面晶粒细化,从而达到增加材料强度的效果.通过对铝合金板进行SMAT处理,材料的极限强度和极限应变虽然有较小的降低,但是其屈服应力有较大幅度的增加.以SMAT处理后的铝合金板和玻璃纤维环氧树脂预浸料为原料,通过热压工艺制备成新型GLARE层合板.通过拉伸实验研究和理论计算分析了该GLARE材料的拉伸性能,发现SMAT处理的铝合金板制成的GLARE的屈服强度提升明显.Abstract: The surface mechanical attrition treatment (SMAT), as a technology that the metal sample surface is hit in random directions by a large amount of tiny hard balls in high frequency vibration within a short period of time, was applied to aluminium laminates. Then, the metal’s grain sizes, especially those near the surface, got smaller; and therefor the metal’s yield strength got enhanced. After the SMAT process, the aluminium laminates’ultimate stress and ultimate strain decreased a little, while the yield stress increased obviously. The glass fibre reinforced aluminium laminates were fabricated through heat pressing process with SMATed aluminium and glass fibre epoxy prepreg. From the tensile tests and theoretical calculation, the results show that the SMATed aluminium effectively improves the yield strength of the aluminiumbased composite.
