Glass fiber and carbon fiber composites have huge development space in the future

    Composite materials have been widely used in aerospace vehicles, such as aircraft fuselage, wing, internals, rocket and missile engine shell, missile ammunition box, nozzle, launcher, radome and pressure vessel. Specifically, there are two main categories of subdivided products of composite materials in the aerospace field, one is carbon fiber composite materials, the other is glass fiber composite materials.


    The biggest advantage of carbon fiber composites is light weight and high strength. Aerospace high-end application is its main development direction. Compared with aluminum alloy, the weight reduction effect of aircraft structural parts made of carbon fiber composites can reach 20-40%, reflecting huge energy-saving benefits.

With the continuous improvement of China's technical level, the increase of the application proportion of carbon fiber composites in aerospace, the increase of the number of equipment and the needs of equipment upgrading, the demand for carbon fiber composites in aerospace in the later stage will increase year by year. In 2018, the demand for carbon fiber composites in China's aerospace field is expected to exceed 1100 tons.

    Glass fiber composite material has the properties of corrosion resistance, high temperature resistance, radiation resistance, flame retardancy and anti-aging. It can effectively reduce the quality of aircraft, increase the commercial load, save energy and achieve the quality of light and beautiful. Therefore, glass fiber composites have become an indispensable material in the field of aerospace.

    Compared with carbon fiber composites, glass fiber composites are widely used in China's aerospace field, accounting for a higher proportion of the aerospace composite market, accounting for about 14.2% in 2017. This proportion is expected to continue to grow. By 2023, the proportion of glass fiber composites in the aviation composites market will increase to 18.5%.

    China's aviation industry has experienced the development process from repair, introduction and imitation to improvement, modification and self-design and development. The materials used to manufacture aviation products have also experienced the development process of introduction, imitation, improvement, modification and self-development. Although China has made great progress in the production and R & D of composite materials, there is still a certain gap compared with the advanced level of foreign countries. The existing composite materials are inferior to similar foreign products in terms of technology, equipment and preparation methods. In particular, the amount of composite materials used in military fighters is far lower than the total amount of composite materials used in foreign advanced fighters. In the future, with the further development of domestic composites, the number of composites used in aviation is expected to increase, and the development space of aviation composites industry is still huge.

    With the development of science and technology and the attention paid to the development of aerospace industry in China's military and civil fields, in addition to the corresponding needs in the military field, the demand for aviation express and other related businesses is also increasing in the future. Therefore, the market demand for aviation materials is increasing. Under the influence of strong demand and the supply of raw materials and products, it can be expected that with the rapid development of downstream industries, China's aviation material demand will show a continuous growth trend, and the prospect of aviation composite industry will be more clear.
