With the requirements of light weight and environmental protection in automobiles, the foreign automobile industry is more and more inclined to use GMT
materials to meet the needs of structural parts, mainly because stitched chopped strand mat
materials have good toughness, short molding cycle, and production efficiency. It is regarded as one of the materials in the 21st century with a series of advantages such as high cost, low processing cost and no pollution to the environment, and is mainly used in the production of multifunctional brackets for passenger cars, instrument panel brackets, seat frames, engine guards, battery brackets Etc., the Audi A6 and A4 cars currently produced by FAW-Volkswagen have adopted stitch mat fiberglass
materials, but they have not achieved localized production.
In order to improve the quality of the whole vehicle to catch up with the international advanced level and achieve the purpose of weight reduction, shock absorption and noise reduction, relevant domestic units have carried out research on the production of GMT materials and product molding processes during the 8th and 9th five-year period, and have mass production. The capacity of GMT material, the production line with an annual output of 3000 tons roving mat
material has been built in Jiangyin, Jiangsu, and domestic automobile manufacturers have also adopted GMT material in the design of some models, and have started batch trial production.
