A pipe coupling for triple wall corrugated plastic pipe includes a triple wall corrugated bellmouth connector that is of a unitary construction with one end of the corrugated plastic pipe. This bellmouth connector is of higher strength and in cooperation with the two wall corrugated spigot provides a high strength coupling. This coupling includes the bellmouth connector and spigot that are made inline with the corrugated pipe. A method for the manufacture of the pipe includes controlling of an air pressure on the outside of a formed two wall corrugated pipe as an exterior third wall is secured thereto.

A flow diversion device for treating branch point aneurysms that includes a wire stent frame comprising a plurality of wire elements, the wire stent comprising a proximal limb and two distal limbs, wherein the proximal limb and the two distal limbs converge at a crotch of the wire stent frame. The plurality of wire elements may be braided together. The flow diversion device may have a substantially Y-shape or T-shape. The flow diversion device may be manufactured by using two tubular flow diversion devices to make a Y-shaped flow diversion device.

An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.

A composite drill pipe including an inner pipe having a first diameter, an outer pipe having a second diameter greater than the first diameter, and a plurality of flow channels formed between the inner pipe and the outer pipe. The plurality of flow channels are formed by a plurality of walls extending radially between an outer diameter of the inner pipe and an inner diameter of the outer pipe. A method of forming a composite drill pipe includes pultruding a drill pipe comprising an inner pipe having a first diameter, an outer pipe having a second diameter greater than the first diameter, and a plurality of flow channels formed between the inner pipe and the outer pipe. The method also includes providing a multi-directional reinforcement over an outer diameter of the outer pipe.

A method for fabricating aircraft engine external target parts including complex geometries utilizes reusable reconfigurable shape memory polymer and conformable woven braided carbon fiber sleeves. The method includes providing a tubular three-dimensional reusable shape memory polymer mandrel assembly designed for a target part, and heating the shape memory polymer mandrel.

A method of forming a joint between a composite component and a metallic component is disclosed. The method includes forming a first groove in an outer surface of the metallic component on a first end of the metallic component. The first groove extends circumferentially on the outer surface relative to a center axis of the metallic component, and the first groove extends radially inward from the outer surface relative the center axis. The method further includes inserting the first end of the metallic component into a first end of the composite component. A second groove on the composite component over the first groove of the metallic component such that the composite component extends radially inward into the first groove of the metallic component. A composite hoop reinforcement is then applied in the second groove in a circumferential direction and the composite component, and the composite hoop reinforcement are solidified.
