Abstract
A self-supporting, dimensionally stable carbon composite member or laminar carbon member, having a plurality of carbon felt layers adhesively joined to a thin, uniformly thick polygranular carbon members. The carbon members are formed by applying a shearing force, through a roller, to a plastically deformable carbon composition having a filler and a coke binder. The amount of binder varies, from 50 to 150% by weight relative to the filler material, depending on whether the filler is composed of granular, or pulverulant, and/or fibrous carbon particles. To form the carbon composite member, two different method may be used. In the first method, the rolled carbon member is subjected to a thermal treatment to harden the binder. A binder is then applied between the carbon member and the carbon felt layer. All three components are then subjected to a thermal treatment that consolidates or hardens the binder. Alternatively, the carbon composite member can be formed by taking the carbon member after it has been rolled, placing carbon felt layer on the carbon member, and the subjecting of the components to a thermal treatment. In this process, the binder will harden so as to adhere the carbon members and carbon felt layers together.
