Abstract
Experimental evaluations on interlaminar and intralaminar fracture of multilayered and sandwich epoxy and polyester fabrics show an interesting behaviour at delamination initiation and crack propagation. Mode I and Mode Il tests were done on layered specimens with same type of ani ficial delamination to investigate the material influence on interlaminar fracture toughness and crack propagation. In sandwich specimens with a rigid foam core, the intralaminar damage failure and propagation are monitored.
