    摘要： A sandwich skin construction that is comprised of an internal structure comprising a plurality of cones disposed between two outer skins is disclosed. The interior contains a pressurized gas to give the resulting sandwich skin construction added strength over a similarly constructed non-pressurized structure of the same material with an equivalent mass. Various attributes of the cones can be adjusted, for example, size and angle, to optimize the performance of the sandwich skin construction to a variety of external stresses. Moreover, a method is provided for manufacturing the sandwich skin construction. The structure can be placed in a pressurized environment before attaching the outer skins.

    摘要： An end fitting closes at least one end of a passageway having an external periphery and an internal periphery to be cast-in-place within a part. A fitting body has at least one elongated, blind-ended aperture formed therein. The aperture is defined at least in part by a first surface having a complimentary shape with respect to the external periphery of the cast-in-place passageway for receiving an end of the passageway disposed extending at least partially therein to close the passageway during casting of the part. The fitting body is composed of material essentially identical to material being used during casting of the part. The fitting body is positionable within a casting mold for forming the part to be cast, such that machining the cast part after casting opens the blind-end of the fitting to allow fluid flow through the passageway cast-in-place within the part. The end fitting may include a shaped aperture, such as a hexagonal shape or oval shape, for receiving a complimentary shaped nut on the conduit or complimentary shaped passageway to provide orientation of the passageway with respect to the fitting when connected thereto.

    摘要： For producing connections made from composite material for structures having at least two hollow or non-hollow bars, interconnected by at least one hollow connecting joint, separate production takes place of blanks of said different parts with the definitive shapes, but in which the impregnation resin for the assembly of said blanks has not yet been introduced, after which they are assembled by thermosetting resin transfer molding, so as to produce the resin matrix of the connecting joint or the complete structure at the same time as the assembly. The blanks of the connecting joints are obtained by compressing a planar textile complex formed from hot preformable textile fibers between a cavity of a shaping mold and a countermold, by cutting and folding down onto the countermold the overlap parts and performing a thermal preforming cycle.

    摘要： This invention is directed to a thermal barrier layer particularly adapted for insulating a solid flowable particulate polymeric pressure transfer medium from elevated temperatures during high temperature molding. A method useful with the thermal barrier comprises transferring pressure from a pressure means via the thermal insulation layer to an article and exposing the article to temperatures of about 316.degree. C. to about 1371.degree. C. An exemplary thermal barrier comprises at least two flexible layers of beads having a thermal insulation of less than about 2 k.
