Domestic enterprises continue to make breakthroughs in key technologies, and the aviation composite materials industry has broad development prospects

Composite materials refer to new materials that use advanced material preparation technology to optimize the combination of material components with different properties, while aviation composite materials refer to composite materials used in the field of aircraft manufacturing. There are many types of aviation composite materials. According to the different body materials, they can be divided into three categories: organic material-based composite materials, inorganic non-metallic material-based composite materials and metal-based composite materials. According to the different shapes of the reinforcements, they can be divided into particle-reinforced composite materials. , fiber-reinforced composite materials and plate composite materials, and each sub-category also contains more different types of composite materials.

Aviation composite materials are used in aircraft tails, rear fuselages, radomes, ailerons, spoilers and other parts. The upgrading and development of composite materials is the material guarantee for innovative production of aviation equipment parts. Aerospace composite materials need to have characteristics such as high specific strength, high specific modulus, strong fatigue resistance, good electrical conductivity, and good heat resistance, so as to meet the working requirements of aviation equipment in special environments. At this stage, my country’s multi-category aviation composite materials have achieved technological breakthroughs. In the future, the localization rate of domestic aviation composite materials will continue to increase, and the industry has broad prospects for development.

According to different types, fiber-reinforced aviation composite materials can be divided into reinforced composite materials such as glass fiber, carbon fiber, aramid fiber, quartz fiber, potassium titanate fiber, and alumina fiber. Among them, from the perspective of carbon fiber composite materials, the Chinese Academy of Sciences has made breakthroughs in T1000 technology and achieved mass production, breaking the technology monopoly of American and Japanese companies; from the perspective of glass fiber composite materials, China Jushi has successfully localized the sizing agent raw materials and formula technology. Instead, China has realized the localization of the world’s leading glass fiber formula technology.

Against this background, the size of my country’s aviation composite materials market has shown continued growth. According to the“In-depth Market Research on the Aviation Composite Materials Industry 2022-2026″ released by the Industrial Research Center and Investment Strategy Suggestions Report” shows that the domestic aviation composite materials market size will be 47.59 billion yuan in 2021, and it is expected that by 2025, its market size will reach 102.95 billion yuan. At present, domestic aviation composite materials manufacturers include Guangwei Composite Materials, China Jushi, Zhongjian Technology, AVIC Hi-Tech, Zhongfu Shenying, Zhongzhi Co., Ltd., among which AVIC Hi-Tech is the leading company in the civil aviation composite materials industry, accounting for the largest market share ; followed by Guangwei Composite Materials and Zhongfu Shenying.

Aviation composite materials are important raw materials for aviation equipment manufacturing. Its industry development is closely related to the development of aviation technology. In recent years, the proportion of aviation composite materials to the total material consumption of aviation equipment production has been increasing. For example, the proportion of composite materials used on the ARJ21 passenger aircraft is 9 It accounts for about 13% of the C919’s body structure. Industrial Analysts personnel said that driven by demand, my country’s aviation composite materials companies have increased their research and development efforts. At present, some materials have achieved significant results. Technological breakthroughs, the localization rate continues to increase, and the industry development prospects are good. In the future, as domestic aviation equipment continues to develop in the direction of lightweighting, innovation will become the main driving force for the development of the industry.
