Detection of the Impact of Volatile Substances on Windshields of Automotive Non metallic Materials. Automotive interior decorative materials, such as engineering plastics, textiles, leather, non-woven fabrics, and various adhesives used to install these materials, under high temperatures, their easily volatile components will evaporate and form condensation on car windows or windshields, causing poor visibility for drivers and seriously affecting driving safety. Today, the Baijian Laboratory will share with you the testing projects of non-metallic materials in automotive components There are many non-metallic materials used in automobiles, and the same material has different performance requirements when used in different parts, which requires testing of various items. For example, tensile strength, tear strength, hardness, bending strength, color, friction coefficient, and so on. In addition, various adhesives are also extensively used in the use of automobiles, and the performance of the adhesives has a crucial impact on the overall quality of the vehicle. Therefore, it is necessary to conduct performance tests on this type of non-metallic material such as shear, tensile, and tear off
