摘要： A structured three-phase composite which include a metal phase, a ceramic phase, and a gas phase that are arranged to create a composite having low thermal conductivity, having controlled stiffness, and a CTE to reduce thermal stresses in the composite when exposed to cyclic thermal loads. The structured three-phase composite is useful for use in structures such as, but not limited to, heat shields, cryotanks, high speed engine ducts, exhaust-impinged structures, and high speed and reentry aeroshells.

摘要： Systems and methods for coldworking metal are described that reduce the axial flow of metal and increase the radial/tangential flow, thereby improving the fatigue life at an aperture. A tool is inserted through an aperture and its travel speed is reduced when in contact with the metal to reduce axial plastic flow. A sensor as part of the motive system moving the mandrel can sense when the tool contacts the metal and reduces the speed of the tool. The tool may move more quickly when not in contact with the metal to reduce working time than when the mandrel is working the metal. The coldworking tool engages the metal at the aperture at a speed of less than the speed which results in the time duration for the mandrel engaging the metal at the aperture for 35 second per inch of metal thickness at the aperture.
