Stern EWS produces fabrics of interconnected tubes for use in inflatables, such as side-impact airbags, de-icer boots on aircraft leading edges, and escape slides. Conventional inflatable designs glue or sew 2 layers of broadwoven coated fabric together, with at most 10 stitches per inch. The bonds are not optimal.
By using Stern EWS's woven interconnected tube technology, as many as 100 “stitchers” can be effectively woven into a woven seam line, thereby increasing the seam strength by an order of magnitude. The seam is stronger than the fabric itself. For instance, in A5921 the (warp x fill) count is 100x100, allowing for 100 interstitial stitchers to be woven into every inch of the seam. The woven tubular fabric is then rubber coated on both sides and used in the leading edge of aircraft for de-icer boots.
Stern EWS's woven interconnected tube technology eliminates failures in use from seam delamination or seam-related stress concentrations common to conventional tubular designs.
