tape is made with aramid fabrics woven from DuPont Kevlar 49
yarn. It is approximately 5 oz/yd
, 17 x 17 construction using 1140 denier yarn, thickness approximately 9 mils, 50-yd rolls. It is the same construction as style 281 broad goods. This tape is used in the same way as fiberglass but it is lighter and has much greater toughness. They carry bias tape in glass, polyester, and aramid fibers. The bias materials are stronger for a given weight because all of the fibers cross the seam line. They also conform around curves better. The glass tapes are extra heavy weight so just one layer makes a tough seam. The widths and weights listed are not precise; because of its construction, the width of any bias tape can be adjusted somewhat as it is laid up. Less-than-roll quantities are sold by the yard.
