Long Carbon Fiber Reinforced PEEK (Polyether Ether Ketone) is an ultra-high-performance thermoplastic composite designed for extreme engineering environments. Reinforced with 40% long carbon fiber, PEEK-LCF40 delivers outstanding mechanical strength, wear resistance, chemical stability, and continuous high-temperature performance. It is widely used in aerospace, automotive, energy, and high-end industrial applications where metal replacement and long-term reliability are required.
PEEK-LCF40 consists of a polyether ether ketone matrix reinforced with 40% long carbon fibers. The long fiber network significantly enhances load transfer efficiency, resulting in superior stiffness, fatigue resistance, creep resistance, and dimensional stability compared with short carbon fiber PEEK materials.
