A process of bonding a plurality of thermally stable, high strength graphite fiber reinforced glass matrix composite materials is described. The process comprises applying to the surface of at least one of the composite materials to be bonded, a mixture of low softening point glaze such as high lead oxide containing glaze, a high melting point low coefficient of thermal expansion material such as beta-spodumene and colloidal silica followed by hot pressing the composite materials to be bonded together. The resultant bonded articles and the glass compositions particularly adapted for this bonding process are also described.
