Carbon fiber reinforced plastic (CFRP) laminates are used in various industrial fields because they have excellent properties such as a specific strength and a specific stiffness. The use of CFRP in the manufacture of automobiles can lead to a significant reduction in automobile weight, thereby improving the vehicle mileage as well as reducing CO2 emissions. On the other hand, the issue of passenger safety in case of collisions should also be clarified when employing CFRP in the fabrication of automotive structures. The objective of this study is to investigate the response behavior and energy absorption characteristics of CFRP/Steel hybrid plates which consisted of a steel and three types of CFRP laminates under low-velocity impact bending load. We performed drop weight impact tests under the boundary condition of three point bending; the tests involved dropping an impactor from a height of 1.5 m so that the impactor speed just before impact was approximately 20 km/h. With regard to the impact response behavior and absorbed impact energy, the UD-0 specimen showed better performance than the other specimens.
