In the automobile weight reduction methods, the weighting effect can be introduced by maximizing the advantages of metal materials and composite materials and using a suitable material for the parts. In this study, to reduce the weight of the automotive parts, the hybrid control arm was formed by metal and plastic insert injection and its stiffness was evaluated. For this purpose, the front wheel control arm used in the crossover utility vehicle was selected for research. Next, structural analysis using the commercial s/w was performed on the hybrid control arm. Stress and strain were obtained through structural tests. In addition, the structural analysis and stiffness test results were compared and evaluated to verify the accuracy of the structural analysis. Based on these results, the safety of the hybrid control arm was verified.
