ADVANCED COMPOSITE CARBIDE NOZZLES.

Authors: R. P. Radtke; L. M. Swope; AEROJET-GENERAL CORP SACRAMENTO CA
Abstract:
The purpose of this program is to develop two thermal-shock-resistant composite carbide systems that can be reliably used with high-flame-temperature solid rocket propellants. These are: a microcomposite of monocarbide (tantalum, hafnium) and a tantalum-carbide-coated, tantalum carbide/graphite hypereutectic. During this second quarter, the processing variables required to develop the microcomposite structure were established utilizing a hot-press fabrication technique. Work was initiated to develop a tantalum carbide/graphite hypereutectic composite by a fusion and drop casting technique. (Author)
