Abstract: The distribution of residual stresses of ARALL with different prestresses is calculated by finite element theory. A new method for regulating the residual stress, that is, introducing interim layer between aramid and Al layers, is given out. Applying prestress to the laminate has strong effects on the distribution of normal stress along the fiber direction. The interim layer in fiber direction presents a state with gradient distribution.
