Nowadays, CFRP (Carbon Fiber Reinforced Plastic), a composite material combining carbon fiber and resin, is utilized in various fields such as reinforcement of aircraft and fuel tanks for hydrogen vehicles due to its light weight and high specific strength. As shown in many reports, CFRP strength has been investigated under the uniaxial tension whereas there are few reports about the fracture behavior under multiaxial stress close to practical condition. So, we design a unidirectional CFRP specimen with a cruciform form to conduct a test under inplane bi-axial load. In this study, with regard to the strength in the vertical direction (90°), it is described how the presence of loading in the fiber direction (0°) affects the fracture behavior.
