There is provided an integral textile composite fabric of non-woven, needled textile fibers which comprises at least one organic textile fiber layer of laid and needled textile organic fibers, at least one glass fiber layer of laid and needled glass fibers, and a plurality of needled stitches composed essentially of the organic fibers from the organic fiber layer needled in and disposed substantially through the glass fiber layer. The layers are bound together at their inner surfaces, are substantially non-detachable from each other and form an integral textile composite fabric having substantially uniform and high physical properties. There are at least 700 stitches per square inch passing through the glass fiber layer, and the organic fiber layer is essentially free, at least on the outer surface thereof, of glass fibers displaced from the glass fiber layer.

An integral textile composite fabric of non-woven, needled textile fibers comprising: (a) at least one organic textile fiber layer of laid and needled textile organic fibers, said layer having an inner and an outer surface; (b) at least one glass fiber layer of laid and needled glass fibers, said layer having an inner and outer surface; (c) a plurality of first needled stitches composed essentially of said organic fibers from said one organic fiber layer needled in and disposed substantially through said one glass fiber layer while the fibers of the said glass fiber layer are substantially undisturbed, whereby the said stitches bind the said layers together at their inner surfaces, the said layers are substantially non-detachable from each other and form an integral textile composite fabric having substantially uniform and high physical properties, and wherein there are at least 700 stitches per square inch of said binding stitches passing through said one glass fiber layer and wherein said one organic fiber layer is essentially free, at least on the outer surface thereof, of glass fibers displaced from said one glass fiber layer.
