Industry Insights

As an important part for the development of science and technology and national economic construction, advanced material is one of the three key technologies in twenty-first century which relate to national security and promote technological progress and economic development. As a creative and pioneering branch in the field of materials science, aeronautical material with its preparation technology is one of the three key technologies of aviation industry as well as the material basis of aviation modernization and high-tech development. As the forerunner of aviation technology and the core key of advanced aircrafts and aero engines, aeronautical materials is the basic factor of aviation product technical performance, survivability, prolong life and economic affordability. The development and application of aeronautical materials also reflect a country’s comprehensive strength and level of technological development.

In the process of aviation manufacturing development, the replacement of materials shows a fast change speed; what’s more, materials and aircraft have been continuously developing with mutual promotion. "A generation of materials, generation of aircraft" is a true portrayal of the world aviation history.

In the past 20 years, aeronautical materials have made significant development. Active aircraft airframe dominates by aluminum alloy materials. Compared with decreased steel, the amount of titanium alloy has been significantly increased, besides, resin matrix composites has been fully applied on the bearing parts. In the aspect of interior materials, in order to improve the aircraft fuel efficiency, reduce operating costs and enhance cabin comfortable experience, composite interior materials demand in the proportion of each delivery of the passenger plane will greatly improve. Composite materials has a bright future in the manufacture of aircraft interior due to a combination of low flammability, light weight, high strength, durability and appearance characteristics. By 2022, the civil aircraft cabin interior materials by use of carbon fiber composite materials will have reached parity with glass fiber composite materials.

The Basic Requirements of Modern Aeronautical Materials

High performance
High function & multiple functions
Near net shape process
Low cost Environmental compatibility

The development goal and trend of modern aircraft structure materials is

To develop the specific strength, specific stiffness, high toughness and high damage tolerance, corrosion resistance, resistance to environmental advanced structural materials and the overall structure of erosion, realize the structure weight loss.
To develop the structure of bearing and functional integration materials.
To strengthen the research on the fatigue life of the new material, the durability and damage tolerance, improve airframe service life and reliability.
Pay attention to the research of new material and preparation technology, continue to reduce the cost of manufacture and maintenance.

For the half century, with the development of the aviation industry, a technical team focusing on R&D, production and application of aeronautical materials in China has been established. But there still remain some problems in the fields of turbine blades, turbine blisk, titanium alloy, aluminum alloy, ultra high-strength steel, composites construction and its preparation process. With the announcement of "The 13th of Five-Year-Plan" and "Made in China 2025" strategies, Chinese aviation manufacturing and aeronautical materials industry will welcome a tremendous development. Under this background, CAMPS 2015 will be held on November in Beijing.
