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.

 

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.

 

Asphalt represented by Japan Kureha is the mainstream in the insulation industry. Insulation felts in Europe and the United States are basically based on viscose, while most of China uses polypropylene as the raw material. The process is to cut the polyacrylonitrile-based carbon felt or viscose-based carbon felt into the required size, roll it into a tube and put it into a container made of a graphite material, and place the graphite container in a high-temperature furnace (the high-temperature furnace is a graphite tube furnace, intermediate frequency, High-frequency induction furnace or other high-temperature furnaces with the heating method), with the protection of vacuum or high-purity inert gas, heating to 2200 ~ 2500 ℃ at a heating rate of 100 ~ 300 ℃ / h, then naturally cool to 100 ℃.
