RESIDUAL STRESS AND DEFORMATION OF COMPOSITE LAMINATES DURING CURING PROCESS

This paper deals with residual stresses and deformations of composite laminates during cooling down stage of curing process.The numerical results slyow that the nonlinearity of thermal physical and mechanical properties is important to predict residual stresses and deformations of composite laminates.The coupling effect between stress and change rate of mechanical properties with temperature must be taken into account in the residual stress and deformation analysis.
