Abstract
A refractory composite structure is formed which comprises a ductile refractory metallic layer with a roughened surface which is tightly bonded to a refractory composite structural shell. The roughened surface is preferably dendritic in form and produced by chemical vapor deposition techniques. The refractory composite structural shell is preferably a carbon-carbon composite formed by applying a carbon filament preform to the roughened surface, infiltrating the preform with a carbon matrix precursor, and carbonizing the precursor.
