摘要： A high temperature multi-layer thermal insulation is constructed especially for insulating spacecraft. For this purpose the insulation is formed of a plurality of porous material layers, such as ceramic fiber layers, separated from each other by highly reflective gas permeable foils. The insulation has an outer hot side and an inner cold side. The ceramic fibers are so arranged that the layer density increases from the outer side toward the inner side while the fiber diameter decreases from the outer side to the inner side. Compared to conventional heat shield type insulations of spacecraft, the present insulation is relatively lightweight and is able to better discharge again at lower flight altitudes any heat stored in the insulation at higher transient re-entry altitudes.

摘要： A novel isotropically reinforced microcomposite is described. An entirely fluid-phase method has been devised for producing the net-shape filamentary structures. The process depends for its success on the ability to generate in situ, within a shaped mold, a three-dimensional random weave of carbon filaments by catalytic decomposition of a hydrocarbon feed. Almost any desired filament filler matrix combination can be produced by utilizing chemical vapor deposition to modify the surface and bulk properties of the filamentary structure. Infiltration of filler matrix materials can be achieved by adaptation of existing materials technologies.

摘要： An improved method for encasing objects in metal is disclosed as are the novel encased objects so prepared. An object is wrapped with a sheet comprising sinterable particulate or powdered metal and an organic binder, and is the fired to volatilize the binder and to sinter the particulate metal into a unitary metal structure. In the preferred embodiment of this invention, the object to be encased is a green sinterable particulate object which undergoes sintering simultaneously with the particulate metal casing during the firing step.

摘要： A metal matrix composite is produced by plastically deforming a metal powder, either or after blending the powder with ceramic fibers, and compacting the mixture at elevated temperatures to achieve substantially full density. Imparting strain energy to the metal allows reduction of the compaction temperature to eliminate reaction between the fibers and the metal or degradation of the fibers. Silicon nitride fibers are thermodynamically superior for use in aluminum or titanium metal matrix composites, since silicon nitride fibers are more stable at the temperatures required for full compaction. Secondary phase reactions are avoided.

摘要： A process for preparing a porous metal plate is disclosed which is adapted to use short metal fiber to prepare the plate. The process is capable of providing a porous metal plate which has increased bending strength and porosity, of which the porosity and thickness are controlled as desired and which has a wide and lengthy shape. The so-formed porous metal plate is capable of being extensively utilized, for example, not only as a filter and a sound absorption material but for a fuel cell, a catalyst and the like. It is formed by applying adhesive onto a surface of a substrate, and embedding short metal fibers in the adhesive. The composite thus formed is then pressed, to push over the short metal fibers, and the composite is then sintered. The substrate is a material which is capable of being burned out, or is a metal net, or is a release paper, so that the final plate will be porous throughout.

They comprise a porous metal support and metal particulate material with the individual particles sinter bonded to each other and to the support. Preferably, the porous articles are formed from austenitic stainless steel containing less than 0.03 parts by weight carbon, have F2 pore ratings at beta=100 of from about 0.1 to about 50 micrometers and are capable of being formed about a bending radius of five or less times the thickness of the article while maintaining their integrity.
