Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung eines porösen, plattenförmigen Metallverbundes. Um ein Verfahren bereitzustellen, mit welchem bei gleichzeitiger Reduzierung der Herstellkosten ein plattenförmiger Metallverbund aus sinterbaren Fasern in beliebiger Grösse zumindest in Bezug auf eine Dimension hergestellt werden kann, wird mit der Erfindung ein Verfahren vorgeschlagen, bei dem Metallfasern in einem Arbeitsschritt gepresst und miteinander verschweisst werden.
Abstract:
An absorbent structure can include a matrix of fibers, wherein the matrix is reinforced with a reinforcing member, such as scrim. The scrim is secured to the fibrous matrix by entanglement of fibers with the scrim and entanglement of fibers in the matrix from opposite sides of the scrim with each other. The scrim layer can be restricted to a longitudinally extending, medial region of the absorbent. In a particular arrangement, the scrim has a cross-directional width dimension which is less than a narrowest width dimension of the fibrous matrix. The scrim can be located between two, opposed, major surfaces of the fibrous matrix. The scrim has a reduced stiffness in the cross direction which promotes fit and comfort of the absorbent structure as incorporated into a disposable absorbent garment.
Abstract:
A puncture resistant footwear sole composite is disclosed with a plurality of layers of woven aramid yarn fabric combined with a matrix resin in an amount adequate to adhere adjacent fabric layers together but not so much that the composite is saturated by matrix resin.
Abstract:
Disclosed is a method of reducing damage resulting from environmental electromagnetic effects on a non-metallic surface. The method includes disposing a polymeric sheet material over the non-metallic surface and disposing a metal layer between the non-metallic surface and the polymeric sheet material. Objects which includes a substrate having a non-metallic surface, a halopolymer sheet material disposed over the substrate's non-metallic surface, and a metal layer disposed between the halopolymer sheet material and the substrate's non-metallic surface are also described. Laminates are also disclosed. One such lamiante includes a metal layer having a first surface and a second surface, a halopolymer sheet material bonded or adhered to the first surface of the metal layer, and an adhesive disposed on the second surface of the metal layer. Another such laminate includes a halopolymer fabric having a first surface and a second surface, a metal layer bonded or adhered to the first surface of the halopolymer fabric, and an adhesive disposed on the second surface of the halopolymer fabric.
Abstract:
The invention provides a thermal insulation blanket suitable for removable mounting on a structure such as the exterior of a reusable launch vehicle. In one embodiment, the invention includes a batting layer with a rigid screen embedded within it. A cover layer is secured over the batting, and a plurality of fasteners are held by the screen in a position where they extend out from the blanket to be mounted on the exterior of the space craft. The blanket can include two layers of batting with the screen disposed therebetween. The structure would have corresponding mating fasteners on its exterior to which those extending out from the blanket cover would be joined for a secure mount. The blanket can be formed of a first and a second batting layer with the screen positioned therebetween. In a preferred embodiment, a cover would be positioned over the batting layers, and the blanket would be quilted to hold the layers and cover in close proximity. In an embodiment suitable for launch vehicle use, the materials used for the batting, cover and quilting thread would be suitable ceramic fiber materials capable of withstanding reentry heating. The screen can be fabricated of titanium, stainless steel, or other material capable of withstanding reentry temperatures. The fasteners could be any of a variety of commercially available fasteners.
