The use of carbon phenolic and carbon-carbon materials in nozzle and exit cone designs has been historically plaqued by the lack of reliable, stistically significant material property data. Property data are needed by designers to analyze thermal response and stress levels and develop designs with safety factors that assume high reliability at minimum weight penalties. The program is sturcuted to provide the data necessary for thermal and stress modeling of tape-wrapped carbon phenolic and involute carbon-carbon components. The work is initially directed at determining critical properties for analysis followed by evaluation of existing data and the determination of data deficiencies. New data will be generated in stististically significant quantities. Alternate materials will be selected and characterized and a final data book will be prepared. Materials to be tested will be excised from Space Shuttle inlet, throat and exit cone billets and modified US and STAR 48 involute carbon-carbon exit cores; co-processed blocks, panels, and cylinders will also be tested. Motion Thiokol, Inc., is fabricating the Shuttle parts. Kaiser and Hitco are fabricating the IUS and STAR 48 components; and Southern Research will do the testing.
