Nano fillers are used as flame retardant fillers in epoxy resin and their. Four kinds of nanofillers are usually used: nanoclays, polyhedral oligomeric silsesquioxane (POSS), carbon nanotubes and carbon nanofibers. Formation of a carbonaceous char layer is the most dominant mechanism for fire retardancy in nanocomposites. For nanoclays a carbonous-silicate structure char layer, for POSS a ceramic-structure char layer and for carbon nanotubes and carbon nanofiber a carbonous char layer are formed during combustion. This char layer insulates the underlying material and limits the passage of degradation products from the matrix.
