Abstract: A method for assembling a composite pressure vessel includes disposing a sealant into each of a plurality of annular slots defined in an exterior surface of a body portion of an end cap. The end cap is aligned with an end portion of a tubular member such that the exterior surface of the body portion of the end cap abuts an interior surface of the tubular member. A force is applied to the tubular member having the end cap aligned with the end portion of the tubular member. The force is applied while rotating the tubular member. The force deforms the tubular member such that the end portion conforms to the plurality of annular slots defined in the body portion of the end cap.

Abstract: A process, for joining workpieces using hybrid mechanical connector-resistance welding. The process in some embodiments includes introducing a conductive fluid to an interface between the workpieces. The process also includes inserting at least one mechanical conductive connector into at least one of the workpieces so that the connector reaches the interface having the conductive fluid therein. The process in some embodiments includes further applying energy for welding to the at least one mechanical conductive connector so that the energy passes, through the connector, to the conductive fluid and heat is generated in the workpieces at the interface, thereby melting the workpieces and forming a weld joint connecting the workpieces.

Abstract: A method of repairing a polymeric composite workpiece. The method comprises identifying a localized area of the polymeric composite workpiece having a defect. A plurality of three dimensional interface structures are aligned adjacent at least a portion of the localized area. The method includes applying a polymeric composite patch to the localized area such that the interface structures are disposed between the polymeric composite workpiece and the polymeric composite patch. An alternating electromagnetic field may be introduced to selectively induce localized heating of the interface structures. The localized heating softens regions of the polymeric composite workpiece and the polymeric composite patch adjacent the interface structures, causing the interface structures to penetrate a distance into the respective polymeric composite workpiece and the polymeric composite patch.
