FABRIC-REINFORCED, FLEXIBLE-WALLED CONTAINER AND METHOD OF MAKING SAID CONTAINER ABSTRACT OF THE DISCLOSURE A flexible, complex-shaped container is characterized by a composite (10) comprising a fabric reinforcement material (12) and at least one facing layer of a polymeric or elastomeric material (14 or 16), said fabric comprised of yarns capable of changing their effective lengths upon being shaped to a complex mold configuration and thereafter maintained in that shaped condition by curing of the composite material. The method of the invention comprises applying a differ- ential pressure to the fabric reinforced composite (10) in a concave mold (30,50) having the desired complex configuration to move the composite into the mold cavities as the effective length of the yarns change to conform to the mold (30, 50) and thereafter curing of the composite so as to set the composite (10a) to the mold shape.
