“…For the consolidation method, fibers were either electroplated [5][6][7][8] , electroless plated [9] , or coated with metallic film by vapour deposition. For the infiltration method, fibers were also specially treated [11][12][13] in order to achieve proper wetting by a liquid metal. Neither method has been used to obtain a metal reinforced component of a large size.…”

Investment casting technique was applied to produce tensile test specimens of graphite fiber reinforced Sn-Pb alloy. To assure good wetting characteristics of the fibers by the liquid metal, they were electroplated with copper. Depending on the pouring conditions (controls of temperatures and centrifuging force) several types of bonding between the fibers and the matrix were observed: a) No bond between copper-plated fibers and the matrix, b) Mechanical contact between the copper coating and the matrix, c) Formation of the intermetallic phases between copper and Sn-Pb alloy, and d) Dissolution of copper coating and direct contact between the fibers and the matrix.Tensile testing of specimens revealed direct dependence of the efficiency of the reinforcement on the type of the interface formed between the fibers and the matrix. Optimum conditions existed when the electroplated copper had reacted with the Sn-Pb alloy, forming intermetallic phases.
