CALCARB is a rigid, high-temperature composite made from discontinuous lengths of carbon fibers, vacuum formed and bonded by a carbonized resin. It is a relatively strong, high-purity carbon material with low bulk density that is readily machinable. This datasheet provides information on composition, physical properties, and compressive strength. It also includes information on high temperature performance and corrosion resistance as well as machining and surface treatment. Filing Code: Cp-1. Producer or source: Calcarb Inc..
