ABSTRACT. THE OBJECTIVE OF THIS WORK WAS TO FORMULATE THE RELATIONS BETWEEN STRESSES AND STRAINS IN CARBON/EPOXY LAMINATES. FROM THESE RELATIONS, A MATRIX EQUATION RELATING THE VECTOR OF LOADS (STRESS AND MOMENTS RESULTANTS) WITH THE VECTOR OF STRAINS AND CURVATURES OF THE MIDDLE SURFACE OF LAMINATES WAS OBTAINED. THE FORMULATION INCLUDES RESIDUAL STRESSES AND THERMAL EFFECTS. A COMPUTER CODE, BASED ON THE FORMULATION PRESENTED IN THIS WORK, WAS WRITTEN, AND SOME SIMULATIONS CONCERNED WITH PRACTICAL SITUATIONS WERE CARRIED OUT. RESIDUAL THERMAL STRESSES OF ABOUT 10% OF THE STRENGTH OF THE MATERIAL WERE OBTAINED, INDICATING THAT THE THERMAL ANALYSIS IS IMPORTANT IN THE DESIGN OF FIBER REINFORCED PLASTIC STRUCTURAL COMPONENTS.
KEY WORDS: COMPOSITE MATERIALS, RESIDUAL THERMAL STRESSES.
