Es wird eine Faserverbundwerkstoff enthaltend eine oder mehrere Lage(n) aus Verstärkungsfasern oder -filamenten vorgeschlagen, der eine oder mehrere damit in Verbindung gebrachte Lage(n) aus Bändchengarnen enthält sowie ein Verfahren zu dessen Herstellung.
摘要:
Systems and methods of providing a composite material that is bendable but substantially resists stretching under tension. One embodiment may take the form of a composite material formed by over-molding a woven glass fiber with silicone. The woven glass fiber may be rolled out with a silicon polymer melted into the woven fabric as the rolling process continues. The composite of the two materials may provide a material that bends easily but does not substantially stretch.

L'invention concerne une ébauche fibreuse (100) tissée en une seule pièce par tissage tridimensionnel pour la réalisation d'une plate-forme à caisson fermé pour soufflante de turbomachine en matériau composite. Dans chaque plan de l'ébauche fibreuse, un ensemble de fils de chaîne lie entre elles les couches de fils de trame de la première (102), de la deuxième (104) et de la troisième (106) partie de l'ébauche fibreuse tout en ménageant une déliaison fermée (108) séparant la première partie de la deuxième partie sur une portion de la dimension de l'ébauche fibreuse en direction chaîne entre une limite amont (108a) et une limite aval (108b) de déliaison, et au moins une déliaison ouverte (110) séparant la deuxième partie de la troisième partie sur une portion de la dimension de l'ébauche fibreuse en direction chaîne à partir d'une limite de déliaison (110a) jusqu'à un bord aval (100c) de l'ébauche fibreuse. L'invention concerne également un procédé de fabrication d'une préforme de plate-forme à caisson fermé pour soufflante de turbomachine en matériau composite à partir d'une telle ébauche fibreuse.
摘要:
An integrally woven three-dimensional preform ( 100 ) with stiffeners in two or more directions constructed from a woven fabric having a first, second and optional third woven fabric layer. A plurality of yarns are interwoven over a region between the first and second fabric layers such that the first fabric layer is foldable relative to the second fabric layer. An additional plurality of yarns are interwoven over a region between the second and third fabric layers such that the third fabric layer is foldable relative to the second fabric layer. Upon folding of the woven fabric layers, the integrally woven three-dimensional preform (100) with stiffeners in two or more directions is formed.

A seamless convoluted hose assembly. The assembly includes: a tubular inner liner having an outer surface, an inner surface, and an inner liner wall therebetween which defines a passageway. The assembly further includes a helical coil or a plurality of annular loops which produce convolutions in the outer surface of the tubular liner when the tubular inner liner is forced through the helical coil or plurality of loops under heat and pressure.
摘要:
A non-disassembling partition assembly (100) comprising a partition matrix (10a) made up of intersecting first and second slotted partitions (12a, 14a), each of the partitions (12a, 14a) having at least one slot (28, 30). The slots (28, 30) of the partitions (12a, 14a) are engaged with each other at a plurality of intersections. The partitions ( 12a, 14a) may be made by folding over a partition blank (66) and securing a foam portion (38) of the folded partition blank (66) to itself. The foam (38) may be heated before being cooled under pressure to secure opposed plies (32,34) of the partition together. The partition assembly (100) is held together by a floor (102) parent welded to the intersecting partitions (12a, 14a). The floor (102) has a lower outer skin (108) and a foam layer (106) to which the partitions (12a, 14a) are parent welded.
摘要:
A thin walled cross-linked polyethylene (PEX) pipe having a reinforcing material disposed around an exterior wall thereof is provided. As the PEX pipe passes through an extrusion die, a thread guide applies a plurality of reinforcing threads in a particular pattern to the exterior surface thereof to allow for uniform three-dimensional (axial and radial) tensile properties so as to achieve optimum reinforcement of the pipe wall while maintaining its flexibility and without significantly increasing the thickness of the wall or the weight of the PEX pipe.

摘要:
The invention relates to methods and devices for producing laminated products from thermoplastic materials and can be mainly used for assembling filtering and sorbtion-filtering materials by means of instant spot thermal welding for producing devices for personal protection of respiratory organs, in particular light respirators. The inventive method consists in carrying out thermal pressing of thermoplastic sheet layers, which are made of flexible material and the cross-section area of which is greater than 1.1-1.4 times the surface area of the working surface of the electrode, using thermoelectrodes and nonheating clamping ends which are arranged along the perimeter of the sheet layers and have a convex working surface. The inventive device comprises a frame, a drive which is provided with electric facilities and is mounted on the frame, the unit of a main rod, which interacts with the drive and is provided with a cantilever arm, and a forming head with a pressing plate and a rod and a forming cavity which comprises a heater provided with a welding circuit in the form of an entirety of thermoelectrodes, a bearing table with holes which are embodied in front of the thermoelectrodes, a flange having a ring, a bearing ring provided with key levers having clamping ends, disposed in the radial grooves of the bearing ring, and spring loaded stops located in front of the key levers, wherein the clamping ends have a convex surface, are made of flexible material and the cross-section thereof is greater than 1.1-1.4 times the surface area of the working surface of the electrode. The invention makes it possible to increase the quality of produced respirators, to simplify the structural design and performance characteristics of the device.
