RESEARCH AND DEVELOPMENT ON ADVANCED GRAPHITE MATERIALS. VOLUME XII. DEVELOPMENT OF AN IMPROVED LARGE DIAMETER FINE GRAIN GRAPHITE FOR AEROSPACE APPLICATIONS.
Abstract
This report describes a method for producing graphite using a pressure curing process which was partially developed prior to initiation of this contract. The process is based on a thermosetting binder system and is employed to develop a reasonable uniform fine-grain graphite. Also presented are the contract supported investigations of the process variables associated with attempting to reach optimum properties and with scaling up to 30-inch diameter sizes. This graphite, designated Grade RVA, is nominally characterized by a bulk density of 1.85 g/cc, room temperature with and against grain flexural strengths of 3700 and 2900 psi respectively, with and against grain elastic moduli of 1.7 and 1.3 million psi respectively, and variations in these properties of only one-half to one-third of those normally associated with quality industrial graphites such as grade ATJ.
