Abstract

A DURABLE, LIGHTWEIGHT, REUSABLE MATERIAL IS REQUIRED FOR THERMAL PROTECTION OF ATMOSPHERIC SYSTEMS AND EXO-ATMOSPHERIC VEHICLES. THIS PROJECT IS DIRECTED TOWARDS 3-DIMENSIONALLY (CARTESIAN) WOVEN CONSTRUCTIONS OF NEXTEL 312 AND NICALON FIBERS IMPREGNATED WITH A POLYCARBOSILANE RESIN. FOLLOWING IMPREGNATION, THESE CONSTRUCTIONS WILL BE PYROLYZED TO YIELD A SIC MATRIX TO PROVIDE HIGH TEMPERATURE RESISTANCE AND OXIDATION RESISTANCE. EVALUATION OF THESE MATERIALS WILL BE CONDUCTED THROUGH THERMAL AND MECHANICAL TESTING AND SCANNING ELECTRON MICROSCOPY OF THE SIC MATRIX/FIBER INTERFACE.
