Flexible microcrystalline zirconium carbide fabric
 Flexible metal carbide fabrics are produced by a process that involves the steps of: PA1 (a) impregnating a preformed organic polymeric fabric with a solution of a metal compound; PA1 (b) heating the impregnated fabric to evolve volatile decomposition products and to leave a carbonaceous relic containing the metal in finely dispersed form; and PA1 (c) further heating the relic to 1000.degree.-2400.degree. C. in a non-oxidizing atmosphere to form the metal carbide. Boron carbide and silicon carbide fabrics produced by this process are attractive for high temperature structural applications.
