The purpose of this study was to investigate the performance and quality of engine mounting member in repair parts of the accident vehicles by conducting mechanical and material properties experiments. The tests were conducted by the test equipments of chemical components analysis, radiographs and mechanical testing on the genuine parts and non-genuine parts of engine mounting member. Test results concluded; Tensile strength of genuine parts is about 270 N/㎟ but damaged non-genuine parts about 200 N/㎟. The chemical component of 12 components was similar genuine part to non-genuine parts but Ti, Ni component were appeared different. Non-genuine parts were 4 times in elongation, 2 times in hardness higher than genuine parts. We concluded that quality identification system of repair parts and circulation system establishment of repair parts market were needed.
