| الوصف: | Among polymeric Thermal Protection System (TPS) materials, Phenolic Impregnated Carbon Ablators (PICAs) offer substantial specific weight reduction. A traditional NASA developed PICA is made starting from a preform or using Milled Carbon Fibers (MCFs) to produce a porous skeleton impregnated with a liquid phenolic matrix; the production methods, allow to obtain a low density porous material showing high ablation resistance. The aim of this research was to produce a nanostructured PICA (n-PICA) based on the use of MCFs, a liquid phenolic matrix, and selected nanofillers. Two different nanofillers were used: Multi-Walled Carbon Nanotubes (MWNTs) and nanoclays. The synergistic effect of the two nanofillers was evaluated in terms of thermal and dimensional stability, mechanical properties and ablation resistance via oxy-acetylene torch. Scanning electron microscopy was used to investigate the exposed and in depth surface morphologies of the oxy-acetylene torch tested specimens in order to highlight the differences in the thermal erosion mechanisms. |
