At the modern industry, the composite material has been widely used. Particularly, the material of
carbon fiber reinforced plastic hardened with resin on the basis of fiber is excellent. As the specific
strength and rigidity are also superior, it receives attention as the light material. Among these materials, the
carbon fiber reinforced plastic using carbon fiber has the superior mechanical property different from
another fiber. So, it is utilized in vehicle and airplane at which high strength and light weight are needed at the same time. In this paper, the tensile property due to the fiber design is investigated through the
analysis study with CT specimen composed of carbon plastic reinforced plastic. At the stress analysis of
CFRP composite material with hole, the fracture trend at the tensile environment is examined. Also, it is
shown that the lowest stress value happens and the deformation energy of the pre-crack becomes lowest at
the analysis model composed of the stacking angle of 60° through the result due to the stacking angle.
On the basis of this study result, it is thought to apply the foundation data to anticipate the fracture
configuration at the structure applied with the practical experiment
