The life expectancy of composite structure requires a clear understanding of the material’s response to the growth of interlaminar delamination under Mode I, Mode II, Mode III and Mixed Modes. Fracture testing of fiber reinforced polymer-matrix composites is an active area of research. Even though substantial progress in the area of fracture testing has been achieved, there are still several problems awaiting solution. The new aspects in the experimental studies of interlaminar and intralaminar fracture toughness of polymer matrix composites were emphasized in this review paper. The different modes to e
