Thermal protection materials are required to preserve structural components of space vehicles during the re-entry stage, in missile launching systems, and in solid rocket motors. The overall proposed research is to develop a model for simulating the insulative behavior of a thermal protection material for solid rocket motors (SRMs). Next, the introduction of inorganic nanomaterials as additives into polymer systems has resulted in polymer nanostructured materials exhibiting multifunctional, high-performance polymer characteristics beyond traditional polymer composites possess. In this study, formulations with the addition of nanoparticles, namely montmorillonite nanoclay and carbon nanofibers, in a pure thermoplastic polyurethane elastomer (TPU) polymer resin matrix were compounded and characterized for their thermal and kinetic properties. Scanning electron microscopy (SEM) was also performed for microstructural studies. Selective results were then compared against the current state-of-the-art thermal protection material, Kevlar®-filled ethylene-propylene-diene rubber (EPDM) as well as the pure TPU for the investigation of properties improvements.
