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 gcc and flexural strengths of 4700 lbssq. in with the grain and 310 lbssq. 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
