Metallic alloys and methods for the preparation of free-standing metallic materials in a layerwise manner. The resulting layerwise construction provides a metallic skeleton of selected porosity which may be infiltrated with a second metal to provide a free-standing material that has a volume loss of less than or equal to 130 mmas measured according to ASTM G65-04 (2010).

Infiltrated ferrous materials

The present disclosure is directed at alloys and method for layer-by-layer deposition of metallic alloys on a substrate to produce a metallic part. Applications for the metallic parts include pumps, pump parts, valves, molds, bearings, cutting tools, filters or screens.

Layered construction of in-situ metal matrix composites

The present disclosure is directed and formulations and methods to provide alloys having relative high strength and ductility. The alloys may be provided in seamless tubular form and characterized by their particular alloy chemistries and identifiable crystalline grain size morphology. The alloys are such that they include boride pinning phases. In what is termed a Class 1 Steel the alloys indicate tensile strengths of 700 MPa to 1400 MPa and elongations of 10-70%. Class 2 Steel indicates tensile strengths of 800 MPa to 1800 MPa and elongations of 5-65%. Class 3 Steel indicates tensile strengths of 1000 MPa to 2000 MPa and elongations of 0.5-15%.

Resin infusion medium and reinforcing composite lamina textile constituted by a warp knit open work structure produced in the form of polygons of which at least some of the edges are defined by knops such as to give prominence to the design to provide for fluidic channels, the knops being knitted to be sufficiently non-compressible in order to resist collapse of the fluid channels during compression of the composite preform under vacuum induced process pressure.

A three-dimensional spacer fabric resin interlaminar infusion medium and reinforcing composite lamina for use in the vacuum-induced manufacture of fiber reinforced polymer composites is described. This use of the three-dimensional spacer fabric as a composite interlaminar component improves both the vacuum-induced resin infusion flow rate and laminate quality control and aids in the achievement of enhanced resin uniformity distribution throughout the laminate.

The present invention is a capacitor of a triphenyl phosphine oxide film as a base dielectric. More specifically, the base dielectric film is selected from the group consisting of Bisphenol-A (Bis-A PEPO). 4&prime;,4&prime;-biphenol (BP-PEPO), and Hydroquinone (HQ-PEPO). TPPO based polymers have a very high breakdown strength, dielectric constant, low dissipation factor and high energy density. An ultra-thin coating can leverage the capabilities of this new dielectric, and potentially other commercial polymer films, to make possible energy storage in excess of 1 J/cc. The triphenyl phosphine oxide film can be fabricated containing a conducting PolyANiline (PAN) polymer layer located between the electrode and core polymer, or by being dip coated with PAN.

An electromagnetic shielding composite having nanotubes and a method of making the same are disclosed. According to one embodiment of the present invention, the composite for providing electromagnetic shielding includes a polymeric material and an effective amount of oriented nanotubes for EM shielding, the nanotubes being oriented when a shearing force is applied to the composite. According to another embodiment of the present invention, the method for making an electromagnetic shielding includes the steps of (1) providing a polymer with an amount of nanotubes, and (2) imparting a shearing force to the polymer and nanotubes to orient the nanotubes.
