The objective of this project is to develop a new corrosion resistant coating based on silses-quioxane materials for aircraft applications. Aluminum alloys for aircraft bodies must be epoxy resin-coated to minimize environmental corrosion. Coating systems currently used in the aviation industry use chromium (VI) compounds as the active chemical to prevent corrosion. These chro-mium compounds are know to be tetrogenic therefore industry seeks to replace them with non-toxic materials. Because silsesquioxane systems can be assembled at nanometer length scales providing the opportunity to tailor global properties and nanometer length scales it is possible to create novel materials that could replace current systems in use for both primer and surface coating applications for aircraft fuselage and structural materials that are primarily aluminum but in the near future will be epoxy-resin/carbon fiber composites. This represents to technology and the approach of this project.
