Characterization of MX Upper Stage Subscale Carbon-Carbons.

Abstract

The most significant characteristics of the carbon-carbon materials employed by Aerojet Solid Propulsion Company in the MX upper-stage subscale nozzle tests have been determined. These carbon-carbons included two dimensionally reinforced structures of both flat laminate and rosette construction as well as a three dimensionally reinforced composite. Results of these studies characterize the materials by their response to the original fabrication process and to the rocket test environment. The evaluation concentrated on microstructural and macrostructural examination, posttest surface roughness measurements, thermal expansion and thermal stability of the composite, and evaluation of the density/porosity/pore structural relationships. Conclusions regarding the materials' operating performance and processing conditions are given, and recommendations for future studies are presented. (Author)
