Evaluation of Tensile Fracture Behaviour of CFRP under Varied Strain Rate with High-Speed Imaging and DIC

Tensile fracture behaviour of CFRP laminate under varied strain rate is examined in this paper. In order to evaluate the fracture behaviour and surface strain distribution change, high-speed imaging technique and DIC (digital image correlation) is applied in combination. CFRP specimen having stacking sequence of [+45º/−45º]S and[90º]6T shows strain rate dependence though [0º]2T specimen does not show clear influence on tensile strength and...
