| Abstract: | Tensile pre-strain was applied to the Aluminium- Aramid Laminates to modify the interlaminar residual stresses, The relationship between residual stresses in aluminium and the pre-strain was analysed. The residual stresses in aluminium of several kinds of pre-strain laminates were measured by means of outer layer corrosion. The influences of prestrain on tensile and fatigue properties of the laminates were also studied. |

| Keywords: | aramid-aluminium laminate(ARALL) residual stress prestrain |
