Abstract: The present disclosure encompasses three-dimensional articles comprising flexible composite materials and methods of manufacturing said three-dimensional articles. More particularly, the present system relates to methods for manufacturing seamless three dimensional-shaped articles usable for such finished products as airbags/inflatable structures, bags, shoes, and similar three-dimensional products. A preferred manufacturing process combines composite molding methods with specific precursor materials to form flexible fiber-reinforced continuous shaped articles.

Abstract: An improved reinforced laminate for use in sails or other flexible sheet or membrane applications utilizes a pull-truded thin lightweight reinforcing sheet of unidirectional extruded monofilaments in which the reinforcing sheet or sheets form one or more uni-tapes laminated to a polymer film such as Mylar, or other extended sheet of material. The monofilaments are uniformly embedded in the uni-tape via an elastomeric polymer matrix, with the reinforcing sheet, when incorporated into sails via lamination resulting in sails with reinforcing monofilaments having diameters 5 times less than conventional strands or threads. The use of small diameter monofilaments greatly increases the monofilament-over-monofilament crossover density, resulting in a dramatic increase in shear strength, and Youngs' Modulus, with an accompanying dramatic decrease in weight. In one embodiment the improvement in specific modulus over conventional sail laminates is about six-fold.
