COPPER-COOLED TUNGSTEN FIBER ROCKET NOZZLE MATERIALS
Abstract
Cu and Cu-Ni alloys were used as a matrix of W fibers for the purpose of obtaining W-W bonding of the fibers. From the experimental results, the following conclusions are made: Maximum strength properties in 25% density compositesin. diam W fibers were obtained by using a matrix of 95% Cu-5% Ni. Maximum strength properties in 75% density composites made with 0.002 in. diam tungsten fibers were obtained by using matrices of 90% Cu-10% Ni and 85% Cu-15% Ni. Another large increase was observed at 70% Cu-30% Ni, and this made with 0.006 in. diam tungsten fibers were obtained by using a matrix of 90% Cu-10% Ni. Maximum strength properties in 75% density composites made with 0.001 in. diam W fibers were obtained by using a matrix of 95% Cu-5% Ni. Maximum strength properties in 75% density composites made with 0.002 in. diam tungsten fibers were obtained by using matrices of 90% Cu-10% Ni and 85% Cu-15% Ni. Another large increase was observed at 70% Cu-30% Ni, and this requires additional investigating. The strengthening mechanism in all of these cases presumably arises from a Ni-W or Ni-W-Cu bond between the W fibers. (Author)
