About this technology
Overview
This innovation focuses on an improved low density ablator with improved structural performance and high temperature capability. A new polymer system consisting of cyanate ester and phthalonitrile resins were used to create this carbon reinforced ablator. Cyanate ester resin is a thermoset resin which has high char stability, high decomposition temperature, low oxygen content, low moisture absorption and high glass transition temperature (400 degrees Celsius). Phthalonitrile resin is another type of thermoset resin which has very high char stability, and high decomposition temperature (480 degrees Celsius).
