Cured graphite felt is also called hard felt, which is divided into long fiber and short fiber according to the length of the fiber. Long-fiber hard felt has a certain shape and self-sustainability because it is laminated with soft felt impregnated with resin. While the short fiber hard felt is formed by breaking carbon fibers and adding binders. Hard felt is generally denser than soft felt, and it can be surface treated in various forms such as graphite paper, carbon cloth, carbon/charcoal, and other coatings. At the same time, according to the raw material of carbon fiber, hard felt can be divided into pitch-based, PAN-based, viscose-based, and so on.
