Abstract: A composite structure comprising a fabric layer encapsulated in a silicone polymer or silicone rubber matrix. The fabric layer preferably comprises a woven fabric that includes apertures through which silicone polymer may penetrate during fabrication to provide complete or virtually complete encapsulation thereof in the silicone matrix Because of the method of fabrication, the fabric layer resides closer to one surface of the composite structure so that its esthetic design can be seen from at least one surface of the composite structure. Relatively heat resistant fabrics such as cotton and Nomex® are specifically preferred as the fabric portion, however, Teflon® coated fibers of other woven materials may also provide preferred structures. The incorporation of a thermally insulating ceramic into the silicone matrix further enhances the thermal insulating properties of the composite.
