Recently, in automotive industry, there has been increasing demand for environment friendly materials for light-weight of vehicles to improve their safety and fuel efficiency and reduce environmental contamination. On the other hand, the weights of these types of vehicles have increased because of additional electronic devices, such as motors or batteries. To resolve these issues, it is necessary to develop parts for vehicles with good specific strength and specific stiffness. In this study, a hybrid composite material was fabricated by stacking CFRP on CR340 plates to increase the specific strength and specific stiffness instead of thick boron steel plates or DP steels, which have been used as reinforcing materials to improve the fracture toughness of the center pillar among vehicle parts.
