복합재 접합부의 파손해석

In tllis paper, failure analysis by the FEM(Finite Element Method) for searching for the optimal condition in joining aluminum space frame and composite body of electric vehicle is considered. When joining FRP plate and AI space frame by mechanical joining like bolting or riveting, pin loaded hole arises essentially. In this case, neighborhood of the hole is the most important part in respect to the strength of joining. So failure analysis with respect to the design parameters was conducted for FRP plate, FRP plate with reinforcement, and FRP plate with insert. Comparison of above thress models was also conducted. By the result, we can get the conclusion that FRP plate with insert most resists failure.
