The fabric is a three-layered double biased fabric, the first layer being comprised of parallel structural fibers biased from the longitudinal center line of the fabric, the middle layer being comprised of parallel structural fibers of twice the weight of the fibers of the first layer and aligned at an angle of 90° to those of the first layer and a third layer of parallel structural fibers of the same weight as those of the first layer and aligned at 90° to those of the second layer. The fibers and layers may be held in place and affixed by use of secondary knitted or sewn yarns or threads, and the entire fabric may be saturated with a curable resin.Field of SearchIncluding grain, strips, or filamentary elements in respective layers or components in angular relationStrand or strand-portions Nonlinear strands or strand-portions With additional layer(s) On each side of strands or strand-portions Oblique to direction of web Fibers Including grain, strips, or filamentary elements in different layers or components parallel SELF-SUSTAINING CARBON MASS OR LAYER WITH IMPREGNANT OR OTHER LAYER Of quartz or glass Including stitching and discrete fastener(s), coating or bond | |
