Core Viewpoint - The article discusses the growing significance of Polyether Ether Ketone (PEEK) in various high-performance applications, particularly in the aerospace, military, and low-altitude economy sectors, highlighting its market growth and advancements in composite materials [1][2]. Market Overview - The global PEEK market is projected to reach approximately $900 million in 2024, with a year-on-year growth of 5% [1]. - China's PEEK market is expected to be around 1.92 billion yuan, accounting for 41.8% of the global market share, indicating stable growth [1]. Material Advancements - Carbon fiber reinforced PEEK composites exhibit superior performance compared to pure PEEK, with a tensile strength increase of at least 100% at room temperature and up to 300% at 150°C when 30% short carbon fibers are added [1]. - The enhancement of carbon fibers helps resist thermal softening of PEEK and significantly reduces wear rates [1]. Applications in Low Altitude Economy - Carbon fiber reinforced PEEK is utilized in manufacturing drone frames, propellers, engine components, and lightweight structural parts for flying cars, such as seats and window frames [1]. - It is also used for the casings of sensors and control systems [1]. Key Players and Innovations - Watteco has developed a high-temperature and high-pressure synthesis process for PEEK, achieving a temperature resistance of over 260°C, suitable for critical components in drones and 5G base stations, with an annual production capacity of 1,000 tons [2]. - Nanjing Julong and its subsidiary have a complete production system for civilian drones, offering automated solutions from prepreg to component formation, with a capacity of 900 tons per year [2]. - Jilin Zhongyan collaborates with Siasun Robot to develop collaborative robot joint modules, achieving a weight reduction of 25% and a repeat positioning accuracy of ±0.02 mm, with a PEEK production capacity of 1,000 tons per year [2]. Research and Development - Professor Wang Guibin's research group at Jilin University has made significant advancements in PEEK resin and composite materials, enhancing interfacial shear strength (IFSS) from 43 MPa to 83 MPa through molecular design and chemical modification [3]. - The group has achieved an IFSS of 107 MPa by grafting PEEK polymers onto carbon fiber surfaces, significantly improving the interaction between the PEEK matrix and carbon fibers [3]. Upcoming Events - The 2025 Polymer Industry Annual Conference will be held in Hefei from September 10-12, focusing on the application prospects of PEEK and its composites in the low-altitude economy [3].
