Solidified graphite felt, also known as hard felt/ Rigid Graphite Felt
Description of Rigid Graphitfe felt :
is divided into long fiber hard felt and short fiber hard felt according to the different fiber lengths in the hard felt. Long fiber hard felt is a graphite felt formed by impregnating soft felt with resin, laminating and solidifying it, and graphitizing it to form a graphite felt with a certain shape and self-supporting properties. Short fiber hard felt is made by crushing carbon fibers, adding a binder, and then molding, curing, and graphitizing them. The density of hard felt is generally higher than that of soft felt, and various forms of surface treatment can be carried out, such as pasting graphite paper, pasting carbon cloth, pasting carbon/charcoal, and coating. Meanwhile, according to the different types of raw materials for carbon fiber, hard felt can be divided into asphalt based hard felt, polyacrylonitrile based hard felt( Pan-based Graphite felt), adhesive based hard felt(Viscose-based graphite felt), etc.
