In this research, the slitting method was employed to determine the through-thickness residual stress profile of a carbon/epoxy laminate. The method involves measuring strains at the back surface of the stressed specimen, while a narrow slit is cut by a CNC milling machine progressively from the top surface of the specimen. The pulse method was selected as the computational approach for the determination of the residual stresses from the measured strains. Results show that thermal residual stresses resulting from the curing process of laminated composites have high values and may play a significant role in the failure of these components.
