In July 2022, Jiangsu Junhua Special Engineering Plastics Products Co., Ltd. won the third prize in the 2022 Changzhou “Smart Manufacturing” Innovation and Entrepreneurship Competition. The winning project is “Research and Industrialization of High-Strength, High-Temperature Resistant Continuous Carbon Fiber Reinforced Polyetheretherketone (PEEK) Composite Materials for Aerospace”.     The R&D and industrialization project of high-strength and high-temperature resistant continuous carbon fiber reinforced polyetheretherketone (PEEK) composite materials for aerospace has solved the pain points of poor wettability, high porosity and weak interface of traditional composite materials, and is equipped with a complete set of domestic processing equipment, controllable process and stable supply of raw materials. The pilot products have been tried by COMAC and CSIC, and the product quality has been recognized by customers. The technical index requirements of the products have reached or even exceeded the advanced level of similar products, realizing import substitution.     This product is expected to have a market of 5-10 billion in the aerospace field, with profits of billions. In the application of fuselage frames, floor beams and reinforcement ribs in commercial aircraft, it is expected to have a market of 1 billion, with profits of hundreds of millions. At present, the domestic market share is relatively large, and sales volume/orders are increasing year by year.     Jiangsu Junhua Special Engineering Plastics Co., Ltd.’s leading products are PEEK polyetheretherketone resin, profiles and their products, which have good temperature resistance, toughness and fatigue resistance, as well as self-lubrication, flame retardancy, implantability and recyclability. They meet the requirements of the aerospace, medical and special machinery industries, and their application areas are gradually expanding. This leading product belongs to the advanced manufacturing high-end new materials cluster developed by Jiangsu Province and the industrial chain “advanced carbon materials” composite materials and “new chemical materials”. In terms of industrial orientation, it belongs to the “core key basic materials” of the manufacturing industry and has 16 years of R&D and production experience.         PEEK polyetheretherketone is an important part of the development of key areas of the aerospace industry to replace imports. It is a core key basic material for the national high-tech industrial chain and “strengthening and supplementing the chain” in key areas. It fundamentally solves the problem of my country’s aerospace PEEK material dependence on imports, the lack of basic raw material support for the development of related innovative products, breaks the foreign monopoly, and realizes import substitution.
