Breakthrough in the research of ten ton high-strength medium modulus carbon fiber in China

high strength medium modulus carbon fiber occupies the core position of the high-performance carbon fiber product system, is the key foundation for the high-performance of carbon fiber, is widely used in advanced strategic missiles, spacecraft, military aviation, civil aviation and other fields, and is an important support to promote the upgrading of advanced composite materials. During the "12th Five Year Plan" period, the Ministry of science and technology initiated and implemented the national science and technology support plan project of "Research on engineering preparation and application process of ten ton high-strength medium modulus carbon fiber". Based on the application needs of high-strength medium modulus carbon fiber and its composites in national defense construction and national economy, the project carried out engineering scale polyacrylonitrile precursor preparation Research on technology integration of pre oxidation and carbonization process gb/t21238 (2) 008 glass fiber reinforced plastic sand pipe, meanwhile, research on application process performance evaluation technology of domestic high-strength medium modulus carbon fiber has been carried out, further improving the engineering manufacturing level of domestic carbon fiber

the project has developed a complete engineering preparation technology for high-strength medium modulus carbon fiber and precursor, which provides a demonstration role for the engineering preparation of high-strength medium modulus carbon fiber in China, improves the technical level of China's high-performance carbon fiber field, promotes the construction and improvement of China's high-performance carbon fiber industry, and lays an engineering technical foundation for meeting the demand for high-strength medium modulus carbon fiber in aerospace, national defense construction and other fields

in order to implement the outline of the national innovation driven development strategy, the outline of the national medium and long term scientific and technological development plan (year), the national scientific and technological innovation plan for the 13th five year plan and made in China 2025, and promote the scientific and technological innovation and industrialization development in the field of materials in China, The Ministry of science and technology has formulated the plan for domestic engineering material suppliers of the special project for scientific and technological innovation in the field of materials during the 13th Five Year Plan period to ensure the cost and delivery time, and defined the thinking objectives, task layout and key directions of scientific and technological innovation in the field of materials during the 13th Five Year Plan period. Key materials and technologies such as high-performance fiber and composite materials, high-temperature alloys, special alloys for high-end equipment, key structural materials for offshore engineering, light and high-strength materials, high-performance polymer structural materials, material surface engineering technology, 3D printing materials and powder metallurgy technology, processing effectiveness and performance advantages of metal and ceramic composite Paek thermoplastic materials are mainly studied, Realize the leapfrog development of research and application of high-performance structural materials in China

comments

carbon fiber is one of the key raw materials in the high-end equipment of the national defense industry and the national economy, major basic engineering, transportation, new energy and other fields. High strength medium modulus carbon fiber is an important structural material supporting the development of aerospace technology. The export growth of China's extruder products will show a stable and progressive situation
