Catalytic Incineration of Graphite Fibers in a Graphite/Epoxy Composite Fire.
Abstract
As the use of graphite-reinforced composites grows, so does the risk of electrical interference caused by free graphite fibers which might be liberated from composite fires. Graphite oxidation catalysts or combustion promoters were evaluated to determine the extent to which they would cause graphite fibers to incinerate during a composite fire. Lead catalysts (PbO and Pb3O4) proved effective in reducing graphite/epoxy composite specimen weights by more than 90% when ignited. However, these results depend heavily on good draft, small conductive and convective heat losses, thin specimens and good catalysts distribution. Additional work is underway to find alternatives to the toxic lead oxides. (Author)
