The fracture process of composite laminates subjected to static or fatigue in-plane loading involves a sequential accumulation of intra- and interlaminar damage, in the form of matrix cracking and crack-induced delamination, before catastrophic failure. Matrix cracking parallel to the fibers in the off-axis plies is the first damage mode observed. It triggers development of other harmful resin-dominated modes such as delaminations. The present article reviews experimental and theoretical studies into the damage mechanisms in cross-ply composite laminates within the framework of damage micromechanics and discusses the effect of intra- and interlaminar damage on the behavior and mechanical properties of laminates, including the work of the authors on modeling matrix cracking and crack-induced delaminations.
