Abstract
Carbon composites are made by mixing carbonizable binder, calcined coke grist and carbon fibre rods or needles of carbon fibre bundles in a hardened matrix, shaping the mixture into an artefact and carbonizing the binder, optionally with graphitizing. The composites may be used as carbon electrodes and have a low coefficient of thermal expanson.
