The purpose of the present study was to clarify the effects of temperature and fiber orientation on the Mode I interlaminar fracture toughness, GI (GIC: GI at initiation, GIR: GI at propagation), of carbon/epoxy composite laminates. In our previous study, the conventional double cantilever beam (DCB) tests were performed to investigate the effects of temperature and fiber orientation in CFRP laminates. It was shown that GI was obviously affected by the temperature and fiber orientation. Especially, in case of the specimen with [45//-45] interface, GIR was considerably affected by both failure mechanisms of crack jumping and fiber bridging. Therefore, in the present study, to suppress the effects of crack jumping and fiber bridging occurred in multidirectional laminates, the side notched double cantilever beam (SN-DCB) specimen is used. DCB tests of [22.5//-22.5] and [45//-45] SN-DCB specimens are conducted at three temperatures, that is, -100°C, 25°C and 150°C. GIC was affected by temperature and fiber orientation, obviously and slightly, respectively. In contrast to GIC, GIR was considerably affected by both temperature and fiber orientation.
