The fracture process in composites proceeds by the formation and propagation of a damage zone. The microfracture mechanisms within the damage zone are primarily responsible for energy absorption and dissipation in the macroscopic fracture and, consequently, influence fracture toughness of composites. With this in mind, crack-induced dynamic damage growth has been studied in transparent glass-polyester composites with chopped strand mat and woven fabric as reinforcements. Damage growth has been recorded by photographing the specimens in quick succession using a Cranz-Schardin-type multiple spark camera. The dynamic damage zone has been observed to propagate, similar to static growth, generally perpendicular to the loading direction; but sometimes the damage zone splits analogous to crack branching in homogenous materials. Higher fibre volume fraction reduces linear damage propagation and increases damage spread in other directions. Damage propagation velocity in the composite appears to be slightly lower than the crack propagation velocity in a polyester resin. |
