Carbon fiber cured felt is a high-performance thermal insulation and reinforcement material designed for applications requiring superior heat resistance, optimized structural integrity, and enhanced mechanical durability. Manufactured through controlled carbonization and curing processes, this felt provides excellent stability, lightweight properties, and reliable compatibility with advanced composite systems. It is widely used in aerospace, industrial thermal insulation, high-temperature furnaces, energy storage applications, and structural reinforcement solutions, ensuring long-lasting efficiency in demanding environments.
Product Overview
Carbon fiber cured felt is made by layering carbon fiber soft felt or forming short fibers into a solid shape, followed by high-temperature graphitization treatment. As a rigid material, it has excellent self-supporting properties, is easy to install and remove, and has strong fiber bonding. Carbon fiber cured felt offers outstanding resistance to gas flow erosion, thermal insulation, low heat capacity, and uniform density, making it particularly suitable for high and ultra-high-temperature environments.
