Graphite Hard Felt - Cylinder
Graphite hard felt (commonly known as carbon fiber composite hard felt, cured felt, carbon fiber-reinforced, etc.) is made by a special process that integrates graphite paper, polyacrylonitrile-based carbon felt, and polyacrylonitrile-based carbon cloth into one body, curing After molding, then primary and secondary high-temperature treatment.
Graphite hard felt has excellent ablation resistance, thermal shock resistance, airflow erosion resistance, and thermal insulation performance. It has the advantages of high rigidity, self-supporting, high strength, no short fiber drop, low thermal conductivity, and other advantages that traditional thermal insulation materials do not have.
