Zusammenfassung:The light-aging test method commonly used in the automotive industry is utilized to carry out light-aging research on automotive instrument panel (IP) materials and bumper materials. On one hand,the impacts of common light-aging test methods on aging degree of automotive component materials are reviewed;on the other hand,the light-aging resistances of different component materials are compared. The results show that, for light-aging behavior of IP materials,the aging degree of the third test method is not severer than that of the second method,but it is severer than that of the first method. The light-aging resistance of IP material A is al-most the same as that of IP material B. With reference to light-aging behavior of bumper materials,the aging de-gree of three common test methods indicates that the aging degree of the sixth test method is not severer than that of the fourth method,but it is severer than that of the fifth method. The light-aging resistance of bumper material D is superior to that of bumper material C.
