Carbon fiber reinforced plastics (CFRP) are expected to be used in many applications, because they have outstanding mechanical properties. However, the fracture behavior of CFRP has a special feature such as an interlaminar shear one. In this paper, the effects of heat treatment and sizing on interlaminar shear strength (ILSS) was investigated. ILSS was improved by 30% under such an optimum condition as heat treating carbon fibers at 150°C-250°C for 10min-15min.
