N2 - Thermal protection materials are required to protect structural components of space vehicles during the re-entry stage, missile launching systems, and solid rocket motors. Novel materials based on nanotechnology creating nontraditional polymers are rapidly changing the technology base for thermal protection systems. In the present study, a nanophase was introduced into the thermoplastic polyurethane elastomer via twin screw extrusion. Thermoplastic polyurethane elastomer pellets were blended separately with chemically modified montmorillonite organoclays, carbon nanofibers, or multiwall carbon nanotubes to create a family of thermoplastic polyurethane elastomer nanocomposites. Flammability properties of each family of materials were studied using UL 94. The addition of different nanoadditive to the thermoplastic polyurethane elastomer drastically changes its flammability properties, charred strength, and failure mechanism.
