16 a material having a cross section like that of fig2 is produced threads 16 of ceramic fabric 12 could of course be metallized at spaced locations to provide finished spaced bonding points as desired fig4 and 5 illustrate an alternate ceramic fabric 26 and a material sheet 28 incorporating ceramic fabric 26 in accordance with another aspect of the invention fabric 26 differs from fabric 12 in that fabric 26 incorporates metal wire 30 which is interwoven or stitched with its ceramic threads 29 individual strands 32 of wire 30 in fig4 are illustrated as being larger than ceramic threads 29 for clarity wire 30 is however preferably from 5 to 10 mils 125 microns to 250 microns in diameter as compared to a typical ceramic fabric thread diameter of 250 microns wire 30 is woven within the ceramic fabric threads 29 to provide spaced wire strands 32 which form a repetitive checkerboard pattern as illustrated adjacent wire strands in the pattern are preferably spaced from one another about at least one eighth inch apart to produce a finished material having bonding along intermittent lines wire strands 32 could also of course be woven closer together with ceramic threads 29 to achieve more continuous bonding if desired this would typically provide a corresponding increase in weight wire 30 can be either interwoven with threads 29 as the fabric is formed or alternately woven after fabric.
