National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

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)
