At the 335th Xiangshan Science Conference held on the theme of "the basic scientific issues of high performance polyacrylonitrile carbon fiber" recently, the executive chairman of the conference and academician Shi Changxu of the National Natural Science Foundation of China pointed out that compared with foreign technology, our country

carbon fibre

There is still a big gap in the field, which is mainly reflected in high performance.

Raw material

Lack of high performance reinforced materials, represented by carbon fibers, has long relied on imports.

Due to the lack of innovation and integration and the expansion of application fields, China's carbon fiber has been greatly restricted.

Zhu Shan, a researcher at Shenyang aircraft design and Research Institute, said that carbon fiber composite material is a new type of structural material which emerged in the middle of 1960s. It has many advantages, such as high strength, high stiffness, good layer design, good fatigue and fracture resistance, good corrosion resistance, good dimensional stability, and large area overall molding. It has been widely used in aerospace vehicles.

Carbon fiber composites are four advanced structural materials of aircraft body together with aluminum alloy, titanium alloy and alloy steel.

Experts attending the meeting believed that the high performance carbon fiber composite material industry has broad application prospects in China.

In view of the urgent demand for high-performance structural materials, such as energy, resources, environment, manufacturing, pportation and other national economic pillar industries, we have developed carbon fiber composite materials that meet the needs of aerospace, high-speed rail pit and large-scale wind power generation equipment. It will not only provide technical support for China's heavy construction and major equipment manufacturing, but also lay a solid foundation for China to pform from a material power country to a material power country.
