Carbon fiber reinforced composites for aerospace and composites for fuselage use will rise
Aviation composite materials are composed of fibers and resin materials. According to the fiber strength classification, fiber-reinforced materials can be divided into carbon fiber reinforced composite materials (CFRP) and Glass Fiber Reinforced Polymer (GFRP). GFRP accounts for 25.8%. It is expected that by 2018, CFRP's share will increase to 67.2% and FRP will decrease to 17.3%.
According to different uses, aviation composite materials can be divided into fuselage composite materials, aviation engine composite materials, and aircraft interior composite materials. In 2013, the composite materials used in the fuselage accounted for 64.6% of the total, the aero-engine composite materials accounted for 6.9%, and the interior of the aircraft accounted for 28.5%; it is expected that by 2018, the proportion of the fuselage will increase to 77.4%, and the aero-engine will account for 4.8%. The interior of the aircraft accounted for 17.8%.
The overall scale of China's aviation composite materials continues to increase
At this stage, the proportion of composite materials in various fields is relatively high, and the overall scale of composite materials is constantly increasing. As the focus of product applications in recent years, the market size has been increasing.
According to the statistics of the "Analysis Report on the Forecast and Analysis of Production and Marketing Demand and Investment of the Chinese Aviation Materials Industry" released by the Foresight Institute of Industry, from 2010 to 2017, the market size of China's aerospace composite materials has been increasing year by year. In 2010, China's aerospace composite materials The market size has reached 2.595 billion yuan. By 2016, the size of the Chinese aerospace composites market has reached 5 billion yuan. As of 2017, the size of the Chinese aerospace composites market has increased to 5.35 billion yuan, an increase of 7.00% over the previous year. According to preliminary estimates, the size of China's aerospace composites market will reach about 5.934 billion yuan in 2018, a year-on-year increase of 10.92%.
Compared with the application of composite materials in the aerospace field, the proportion of composite materials in the aerospace interior decoration field is not high, but the overall development trend is also good. From 2011 to 2017, the average annual compound growth rate of the market size of composite materials in the field of aerospace interior decoration is about 9.5%; by 2017, the market size of aerospace interior composite materials has reached 1.66 billion yuan.
In terms of product breakdown, there are two main types of composite materials currently used in the aerospace field, namely carbon fiber composite materials and glass fiber composite materials. As a kind of high-performance fiber, carbon fiber composite materials have been widely used in equipment, aerospace and other fields. not tall. In 2017, the market size of carbon fiber composite materials in the aerospace industry was approximately 156 million yuan.
Compared with the application of carbon fiber composite materials in aerospace, the market scale of China's glass fiber composite materials in the aerospace field is significantly higher. This is because glass fiber composite materials have corrosion resistance, high temperature resistance, radiation resistance, flame resistance, and aging resistance. Applications in the aerospace field can effectively reduce aircraft quality, increase commercial load, save energy, and achieve light and beautiful results. . Because of this, glass fiber composite materials have become an indispensable material in the aerospace field. In 2017, the proportion of aviation composite materials in the market reached 14.2%, and this proportion continues to increase.
In terms of specific scale, from 2012 to 2017, the market size of China's glass fiber composite materials in the aerospace industry has steadily increased year by year. In 2017, the market size of glass fiber composite materials in the aerospace industry was approximately 1.525 billion yuan, an increase of 5.17% year-on-year. It is expected to be around 1.575 billion yuan in 2018.
Analysis of the development trend of China's aviation composite materials industry
Based on the current development status, the future aviation composite materials industry will present the following trends:
First, the demand for aerospace composite materials will continue to rise, and the demand for carbon fiber composite materials for new models represented by B-787 / A-380 / A-350XWB will increase significantly. China needs to add 6810 aircraft in the next 20 years. The increase in the number of aircraft will drive the demand for aerospace composite materials, and the aviation composite materials industry will enter a new period of development.
Second, technology will continue to advance. Since the founding of the People's Republic of China, China's aerospace industry has developed rapidly, and more new requirements have been placed on aerospace materials. In order to better meet the current requirements for the development of aerospace materials, various models and specifications of automatic molding equipment have been continuously developed, which greatly improves production efficiency and reduces costs. At the same time, the concept of low-cost-oriented innovation in related technologies will have a huge boost, including new materials technologies including fibers and substrates, efficient automated integrated component molding technology (AFP and ATL), and digital molding technology.
Third, in order to meet the development of high-performance aerospace vehicles, research and development of new performance and high-quality composite materials will be further accelerated. At the same time, new concept composite material technologies will continue to be developed, such as nanocomposite technology, high functionality and multifunction, structural / functional integration, intelligent structures, etc., and will become important research content of composite materials.
Finally, move towards intelligence. Intelligent composite materials and structures can not only bear the load, but also sense the changes in the internal and external environment, and can respond to changes in their physical properties or shapes, etc., to achieve self-diagnosis, adaptive, self-repair and other functions. The field of aerospace products has broad application prospects.
