| Abstract: | Residual stresses of the ordinarily cured and pre-stressed unidirectionallaminate are analyzed quantitatively. In order to examine the analyzing formulations,strain gages were embedded in the uni-directional aramid aluminium laminates (ordi-narily cured and pre-stressed) to determine the residual stresses in the aluminiumlayers. The calculated residual stresses are in good agreement with the experimental val-ues in the longitudinal direction. Therefore, the work in this paper can be used to calcu-late, determine and design the longitudinal residual stresses according to the manufac-ture and application demands. |
