Resumen:
In this work, mesoporous silica nanoparticles were synthesized and added to phenolic resin/carbon fiber composites in order to obtain ablative resistance materials. Mesoporous nanoparticles were obtained by sol-gel and the mesoporosity was confirmed by transmission electron microscopy. Unreinforced phenolic resin/nanoparticles composites were first prepared and tested in order to evaluate the effect of the particles on the matrix thermal resistance. Oxyacetylene torch test results obtained for the phenolic resin/silica materials were compared with the standard materials used in the aerospace industry (phenolic resin + carbon black). It was found that the isolation effect of mesoporous structure and the high thermal resistance of the silica nanoparticles produced an increase in the ablative resistance of the phenolic matrix composites.
