Abstract: Automotive interior odor is a topic of high concern for consumers, and the addition of fragrant systems is an important method for various automakers. However, the impact of fragrances on interior materials in a closed automotive environment is currently a blank area. In this paper, we analyze the main ingredient of fragrances and their effects on interior materials, and design two kinds of experiment to verify the effects. The test results show that even with the addition of fragrances under conventional aging test conditions, the materials themselves would not undergo significant changes. However, in the fragrance molecule deposition area, such as fragrance outlet, we preform liquid fragrance directly contact testing, the test results show that most materials will be corroded, especially PC/ABS parts. Based on this situation, we do one more round test with painting samples and evaluate the corrosion degree after test, and it is found that the painting samples had good corrosion resistance. It's recommended that in the subsequent vehicle design process, the high risk area should be designed as a painting part.
