Ablative thermo-protective properties of epoxy composites with high-melting metal nanooxides
The influence of the hardener (polyaminoamide) and nanofillers (mixture of TiO2 and Al2O3 nanooxides) on the thermal protective ablative properties of epoxy resin (Epidian 52) was investigated. The composites were exposed to exhaust gases at temperatures above 1900°C for 120 s. A statistical analysis of the results obtained was performed. The best thermo-protective ablative properties showed the composite based on resin cured with the hardener (mass ratio of epoxy/hardener = 1:1) and 5 vol% of nanoparticles mixture containing 80% Al2O3 and 20% TiO2.
