ABSTRACT:
A structure, preferably a radome (1) which comprises a honeycomb (11) of ceramic cloth in the form of fused woven fibers bonded with a matrix to provide a ceramic fiber composite. The fibers are quartz and the matrix is a silica matrix. A cloth (13) is impregated with polysiloxane so that the cloth is 65% by weight quartz and 35% by weight polysiloxane. One or more layers of the quartz cloth (13) are disposed over both open ends of the honeycomb, the total thickness of the layers on each side of the honeycomb being 0.06 inches. A layer of a paint (15) of polysiloxane containing titanium dioxide is optionally placed over the outermost layer of the resin impregnated quartz cloth. The radome is fabricated by initially providing the honeycomb, placing the resin-impregnated cloth thereover and then heating so that some of the resin penetrates into the honeycomb and some of the resin also pyrolyzes to form holes in the resin-impregnated cloth layers. A polysilazane is then disposed in the holes that are formed to provide a sandwich wherein the outer layers or skin contain unpyrolyzed and possibly partially pyrolyzed inorganic resin.
