摘要

This research focuses on the development of a family of new ablative nanocomposite materialsrnthrough a collaboration between The University of Texas at Austin, Techneglas, and Dyna-Tek.rnThe DT-1116 resin system, based on polysiloxane chemistry was evaluated for potential for use inrnthe next generation of thermal protection system (TPS) materials. TGA and microscale combustionrncalorimetry (MCC) were used to examine the thermal stability and flammability properties ofrnpolysiloxane resin system. These thermal properties were compared with two state-of-the-artrn(SOTA) resins: SC-1008 phenolic and PT-15 cyanate ester resins. The DT-1116 polysiloxane resinrnshowed the highest char yield at 87%. The resin also showed the lowest heat release capacityrn(HRC) with 36 J/g-K. These data suggest that the polysiloxane resin has excellent properties forrnpotential use in ablative materials.
