The modern automobile industry is developing towards energy saving and consumption reduction, which is mainly to reduce the weight of the body. At present, the amount of plastic used in the world has been regarded as one of the important indicators for measuring the level of a country's automobile industry. Lightweight and high-strength LFT materials have also expanded from the production of small batches and a small number of auto parts to the production of large quantities and a wide range of auto parts, gradually becoming the mainstream material for the production of auto parts, especially those with high mechanical strength. Fields such as front end frames, energy-absorbing bumper bumpers, seat frames, underbody panels, etc.
According to statistics, the LFT consumption of the automotive industry accounts for about 80% of the total consumption of the world's LFT industry. In the automotive industry, Europe and the United States consume about 95% of LFT consumption, of which 80% in Europe and 15% in the United States.
The research and development of LFT materials in China began in the 1980s and in the early 1990s. It should be said that the time is similar to that in Europe and America, but the industrialization process and application development are relatively lagging behind. At present, China has formed GMT, LFT-G and LFT-D products with independent intellectual property rights, and has formed a certain production capacity, but there is still a considerable distance from the world advanced level in product quality and variety categories. Among the known domestically produced vehicles, more than 90% of LFT parts and raw materials are imported from Europe, the United States, and South Korea, and their applications are mainly concentrated in models introduced from Europe, America, and South Korea.
