In this research, a composite material based on thermostable polymers, reinforced with nano and micro structures was developed and thermally characterized. The polymer used was the epoxy, the microstructures, Titanium dioxide TiO2 and the nanostructures, the multiwalled carbon nanotubes, those, were integrated into the matrix by the method of ultrasonication in two stages, a first in which they were dispersed in a time of 5 minutes, using a sonicator with energy of 750 Watts, frequency of 20 kHz, 1:1 pulser and 40% amplitude, using as solvent, styrene monomer for a posterior inclusion of the solution obtained in the matrix, corresponding to the second stage, where the previous specifications were followed, for a time of 1 minute. Configurational designs for the thermal protection system were established and characterized under international standard ASTM E 285-80, observing their effect on the form, mechanisms and speed of thermal degradation; and it was reported in terms of thermal gradient. A thermal efficiency of 24% was obtained in the nanocomposite, and an improvement of around 15% compared to non- nanoreinforced polymers.
