ABSTRACT:
A method for preparing reticulate thermoset resin structures is described. Thermoset or thermosettable resin containing foams, prepared by a method wherein thin membranes dividing contiguous cells in a thin membraned, thick stranded thermoset or thermosettable resin foam with interconnected cells are produced, and are thermally reticulated. The foams are preferably thermally reticulated by providing a combustible gas mixture inside the cells of the foam and then igniting the mixture to destroy the foam membranes. The thermosettable or thermoset reticulate resin structures so produced are particularly useful for preparing carbon structures with the same geometry by heating at elevated temperatures under reducing, inert or vacuum conditions.
