Abstract: A method for deep roll peening a workpiece includes deep roll peening a workpiece by moving the workpiece along a feed path through multiple groups of opposed rollers that are arranged in series. Each group of opposed rollers includes a rim that defines a workpiece engagement surface that exerts a deep roll peening force on the workpiece. A deep roll peening system includes multiple groups of opposed rollers. Each of the opposed rollers is rotatably mounted and has a rim that defines a workpiece engagement surface. The workpiece engagement surfaces are spaced apart from each other by a gap. The groups are arranged in series such that the gaps define a feed path for receiving a workpiece into serial contact with the workpiece engagement surfaces.

Abstract: A composite pressure vessel assembly includes a first vessel having a first inner layer and a second vessel having a second inner layer. An outer layer of the assembly is in contact with and substantially envelopes the first and second inner layers. A junction of the assembly has outer boundaries defined by segments of the first inner layer, the second inner layer and the outer layer. A cross-layered component of the assembly is disposed in the junction, the first and second inner layers and the outer layer for adding strength to the junction and restricting delamination.

Abstract: An illustrative example container includes a plurality of internal support members having a surface contour that at least approximates a minimum surface. The plurality of internal support members collectively provide structural support for carrying loads on the container. The plurality of internal support members collectively establish a plurality of cavities for at least temporarily containing fluid. An outer shell is connected with at least some of the internal support members. The outer shell includes a plurality of curved surfaces. The outer shell encloses the cavities.

Abstract: A carrier gas recovery system for use in cold spray manufacturing recovers carrier gas utilized during the cold spray process and recycles the carrier gas for immediate use or stores the carrier gas for future use. The carrier gas recovery system includes an enclosure subsystem, a filtration subsystem, a reclamation subsystem, and a compensation subsystem. An article is placed in the enclosure and particulate matter is carried to the article on a carrier gas stream. Carrier gas in the enclosure is filtered through the filtration subsystem to remove particulate from the carrier gas, and the filtered carrier gas is fed to the reclamation subsystem. The carrier gas either flows to a gas separator, to increase the concentration of carrier gas, or to the compensation subsystem if the carrier gas concentration is sufficiently high. The carrier gas can be stored in the compensation subsystem or used in further cold spray manufacturing.
