Abstract
A method of bonding a graphite fiber reinforced glass matrix composite to a metal structure comprising depositing a layer of eutectic alloy metal component to the bond surfaces of the metal and composite followed by placing the thus treated bond surfaces of the metal and composite together with a layer of eutectic alloy containing such metal therebetween. The metal-bond-composite is then heated to melt the alloy and bond the composite to the metal. Articles formed by such a process are also described. The method has particular utility in bonding cooling channel containing metal bases to graphite-glass composite laser mirrors.
Claims6
A bonded metal-composite material comprising a metal substrate bonded to a thermally stable high strength graphite fiber reinforced glass matrix composite by a bond comprising a eutectic alloy layer sandwiched between two layers of eutectic alloy metal components.
