Crack-fiber interaction in brittle matrix composite has been studied using a layer PMMA/glass composite. Fracture experiment was carried out using SEN specimen and crack tip stress intensity factor was directly measured by a laser caustics technique. The result showed that the critical value of the crack tip stress intensity was constant just before the arrival of a crack at the interface, however, the critical applied stress intensity increased with approaching the crack tip to the interface. Interfacial debonding occurred prior to the arrival of the crack at the interface and the crack growth rate was accelerated after the onset of the interface debonding.
