RESEARCH AND DEVELOPMENT ON ADVANCED GRAPHITE MATERIALS. VOLUME XXXVIII. DEVELOPMENT OF AN IMPROVED LARGE-DIAMETER ULTRAFINE-GRAIN GRAPHITE.

Abstract

The report describes the development, fabrication processes and physical properties of grade RVD graphite (formerly RT-0008), 18-inch diameter by 15-inch length, and an attempted scale-up of this grade to 33-inch diameter. Grade RVD graphite, an extra-fine-grain material formed by pressure curing, is nominally characterized by a density of 1.87 to 1.89 g/cc and flexural strengths of 4700 lbs/sq. in with the grain and 310 lbs/sq. in across the grain. Nozzles made from RVD graphite, tested in a subscale rocket motor, exhibit a low erosion rate and high thermal shock resistance. (Author)
