As one of the seven strategic emerging industries in China and one of the ten key areas of "made in China 2025" and the key areas in the 13th five-year National Science and Technology Innovation Plan, the new material industry is the industrial foundation for the transformation and upgrading of the whole manufacturing industry.

The core manufacturing technology of alumina fiber needling blanket has been tightly blocked by developed countries due to its outstanding product advantages, while China has long relied on imports for this product. A very large application market of alumina fiber needled blanket is the sealing gasket of ternary catalytic converter in exhaust gas treatment equipment of high-end automobile industry. At present, the sealing gasket of automobile industry is monopolized by Mitsubishi of Japan, IBIDEN of Japan, 3M of the United States and other companies. In addition, alumina continuous fiber can be processed into alumina yarn and alumina fiber cloth, which is a material in high temperature refractory fields such as aerospace, national defense and military industry. The successful development of alumina fiber needled blanket has solved the key equipment problems restricting the industrialization of alumina fiber, realized the industrialization and localization of alumina fiber, broke the technical blockade of European and American countries, and laid a solid foundation for supporting key materials for the military industry. Promote the major development of aerospace and military industries; upgrade the manufacturing technology of high-tech inorganic fibers in China, and drive major breakthroughs in high-tech fiber industries such as zirconia and silicon carbide; reduce the procurement cost of alumina products for domestic enterprises and save a lot of foreign exchange funds for the country.
