Thermo-Oxidative Behavior of Four-Directional Carbon-Carbon Composites as Throat Inserts for Solid Propulsion Systems

CODEN: MPCACD

Abstract

Carbon-carbon (C-C) composites are considered as one of the ideal materials of construction for high-temperature applications in rockets and dimensionally stable structures for satellites. Thermo-oxidative behavior of four-directional (4D) C-C composites makes it a candidate material for throat inserts of nozzles in solid propulsion systems. For the realization of throat inserts, although 4D C-C composites can be manufactured by different process methodologies, its selection is crucial, as the methodology dictates the material behavior to meet the functional requirements. In this study, high-density 4D C-C composites are manufactured through a unique combination of processes, which can meet the functional requirements. Thermostructural behavior of 4D C-C composites in an oxidative environment is studied, and critical insights on the performance of the material are established. The material behavior of 4D C-C composites is examined with respect to the operating environment. The phenomenon of ablation for 4D C-C composites is investigated through plasma arc jet testing. The ablation mechanism of the material and its constitutive behavior is proposed.
