The mode II interlaminar fracture of unidirectional graphite/epoxy (AS4/2220-3) and graphite/PEEK (APC-2) composite laminates subjected to impact loading is investigated using the center-notch flexural (CNF) test specimen. Experimentally, instrumented impact testing of the CNF specimen enables the impact force history and the absorbed energy during delamination propagation to be estimated. SEM examination is conducted to assess the influence of impact loading on fracture morphology in the crack initiation and propagation regions of the fracture surface. The initiation toughness under impact loading was approximately 20 and 28 percent lower than the static values for AS4/2220-3 and APC-2, respectively. A 24 and 44 percent reduction in fracture toughness is measured for the AS4/2220-3 and APC-2 composite materials, respectively.
