The aerospace composite materials market continues to grow, and local companies still have considerable room for development.

Composite materials refer to new materials formed by complex spatial combinations of two or more materials with different physical and chemical properties, with different structural scales and levels such as microscopic, mesoscopic or macroscopic. Aerospace composite materials are a high-performance new material system used in aerospace vehicles. They usually have the characteristics of light weight, high strength, radiation resistance, high and low temperature resistance, and fatigue resistance. The aerospace composite materials currently on the market mainly include resin matrix composite materials, ceramic matrix composite materials, metal matrix composite materials, carbon fiber composite materials, etc.

In the field of military aircraft, aerospace composite materials can improve the aircraft body structure and enhance the aircraft's stealth capabilities. Its application scope has gradually expanded from simple parts with low load such as drag plates and landing gear doors to the fuselage and wing box sections. , landing gear systems and other main load-bearing components; in the field of civil aircraft, aerospace composite materials can reduce the structural weight and improve the safety and economy of aircraft operation. Its application scope gradually changes from fairings, spoilers, etc. which are less stressed. The components are expanded to main stress-bearing components such as wings and fuselage.

According to the "China Aerospace Composite Materials Project Investment Feasibility Research Report 2023-2027" released by the Industrial Research Center, with the With the continuous advancement of production technology, the use of composite materials in military aircraft and civil aircraft will continue to increase, driving the expansion of the aerospace composite materials market. In 2017, my country's aerospace composite materials market size was approximately 30 billion yuan, and in 2022, the market size was approximately 58 billion yuan, with a compound annual growth rate of approximately 14% from 2017 to 2022.

Aerospace composite materials are a capital, talent, and technology-intensive industry, and the industry has high technical barriers. After a period of development, my country's aerospace composite materials industry has continued to advance in production technology and has achieved certain technological breakthroughs in some areas, gradually breaking foreign monopolies. However, due to the late start of the industry and weak foundation, the overall production technology is not comparable to the international advanced level. There is still a certain gap between the two countries, and local enterprises still have a lot of room for development.
