ABSTRACT:
A structural fabric (20, 28, 40, 48) and a method for making the same is disclosed. Structural fabric (20) is comprised of a plurality of substantially parallel, uniaxial structural yarn (22) and a secondary yarn (24) for holding the structural yarns (22) in place. The structural yarns (22) are oriented at an angle skewed from both the fabric centerline (26) and a line perpendicular to the fabric centerline (26).
A double biased fabric (28) is made by sewing two fabrics (20) together with secondary yarn (39). An alternate double bias fabric (40) is made by sewing together with secondary yarn (46) the two layers of a flattened helix made from structural yarn (42, 44) running spirally substantially the length of the fabric (40).
A triaxial fabric (48) is made by sewing together with a secondary yarn (56) two single biased fabrics (50, 52) and a layer of longitudinally-extending structural yarn pieces (54).
