Graphite hard felt (commonly known as carbon fiber composite hard felt, cured felt, carbon fiber-reinforced, etc.) is made by 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 Sheet is also widely used in defense, metallurgy, chemical industry, and other industries.
Especially with the rapid development of polycrystalline silicon and monocrystalline silicon industries,
as an ideal material for thermal insulation of high-temperature furnaces, the demand for high-quality hard carbon fiber felt has reached an unprecedented height.
