Abstract

The failure modes and mechanisms of the interior parts of automobiles by cosmetics were studied under accelerated failing conditions of an actual working environment. The covering films for the interior parts were doped with three types of sunblocks and their ingredients. The failure of the doped films was accelerated by increasing the test temperature. The typical failure modes observed in the study were the swelling and cracking of the film's surface by the decomposition and the micro-structural changes of the films. This study can help the automobile company to design a plastic interior covering film for better reliability.
