Wires 0.5 mm dia were used for reinforcing. The matrix was a high nickel alloy EI 435, and the volume content of wire was 24%. Results of tensile strength testing show that the tensile strength of a composite material EI 435 + 30% Mo 1 W wire at a temperature of 1100 deg C in the initial state and after annealing 500 h was 11 to 14 kg/mm/sup 2/. Another composite material of E I 435 plus 24% tungsten wire showed an experimental tensile strength of 19 kg/mm/sup 2/ at 1100 deg C. Other composite materials gave tensile strengths of 22.2, 18.4, and 17 kg/mm/sup 2/ at 1100 deg C. If the strength of the matrix material at 1100 deg C is neglected, the strength is attributed mainly to the strength of the fiber. High-strength Mo wire showed the most promise as a reinforcing agent. (SJR)
