In the field of low power, liquid fueled, ablatively cooled rocket combustion chambers, silica/phenolic liners still represent the most promising way to reduce costs of such devices. At date, the role of nanofillers and of the potential benefits due to their use and synergy with traditional fillers, are not yet investigated. For low-cost state of art silica/phenolic liners, prices of ablators can be significantly reduced without a drastic loss of performances, when an amount micrometric silica powder is introduced in the recipe. The main goal of this research was to improve the comprehension of the role of nanotechnology when introduced in the field of ablative materials. More in details, the authors' research tried to understand if nanofillers like nanoclay and nanosilica can constitute a good replacement for micron sized silica particles.
