20090008825 | Method and Device For Placing Thin Material Layers Onto a Relief Mould - The present invention relates to a method and a device for placing at least one material layer onto a relief mould for producing a composite material. Thereby, an elastically-reversibly deformable body with a surface relief that is designed to correspond to the relief mould is pressed against the material layer, as a result of which the surface of said body is deformed, and the material layer can be picked up. As a result of its elastically-reversible characteristics the body subsequently deforms back to its initial state so that the material layer can easily be placed onto the relief mould. | 01-08-2009 |
20090250921 | Docking and Undocking of Liquid Carrying Lines to and From a Docking Body - A docking system for docking a liquid stream carrying line to a docking body, a line end for docking a liquid stream carrying line to a docking interface of a docking body, as well as to a method for preventing liquid from continuing to flow when undocking a line end of a liquid stream carrying line from a docking interface of a docking body. The docking system includes a line end having a first form that is conically tapered in the direction of flow and a docking interface which is situated on the docking body and has a second form that is conically tapered in the direction of flow. The first conically tapered form and the second conically tapered form are adapted to one another in such a way that, in the docked state, they are mutually set apart in one coupling region by an interspace defined by a sealing ring, concentrically opposing one another. Thereby, the first conically tapered form is equipped on its periphery with at least one cleaning element, which extends from the first conically tapered form toward the second conically tapered form in order to capture liquid that may accumulate in the interspace. | 10-08-2009 |
20100244313 | Method for Handling a Liquid - A method for handling a liquid, in particular for the metered transfer of a liquid that is viscous at room temperature from a reservoir to a receiving container for the purpose of further processing the viscous liquid. In the method the receiving container is filled with the liquid. In this arrangement the liquid is present in a plurality of individual portions. Furthermore, the liquid is cooled such that the individual portions are present in a predominantly solid state of aggregation. Preferably, the individual portions are sufficiently small so that the transferred liquid is a frozen granulate. | 09-30-2010 |

20120018918 | TOOL, ARRANGEMENT, AND METHOD FOR MANUFACTURING A COMPONENT, COMPONENT - This application describes a tool, an arrangement, and a method of manufacturing a component. The manufacturing of the component is achieved by a resin transfer from a storage chamber via a transfer line into a working chamber. Before the resin transfer, taking place, for example by a compressed air charging of the storage chamber, the storage chamber is filled with an amount of resin adjusted to the size of the component. Furthermore, a semi-finished product, consisting of cut-to-size reinforcement fibers, is inserted into the working chamber that is adjusted to the form of the component to be produced. Storage chamber, transfer line, and working chamber are configured in a one-piece mould casing of the tool. The application further describes a component manufactured by the above-mentioned tool or by the above-mentioned method respectively. | 01-26-2012 |

20090050259 | Method for producing single- or multi-layer fiber preforms by the tfp process as well as a backing layer - Disclosed is a method for producing single- or multi-layered fiber preforms by the TFP process with fiber strands, which are aligned substantially such that they are oriented with the flux of force, are laid on a backing layer and are attached by fixing threads, in order to form a fiber preform with virtually any desired material thickness and without a troublesome backing layer. A release layer is applied at least in certain regions to the backing layer and, after completion of the TFP process, the fiber preform is introduced into a fixing device, in which at least some of the fixing threads are melted by heat being supplied, and subsequently the backing layer, separated from the fiber preform by the release layer, is detached from the fiber preform. The fiber preforms formed by this method have a virtually optimum fiber structure without flaws along with virtually any desired material thickness and are predestined for the production of composite components for load-bearing components that have to withstand high mechanical loads. A backing layer for the production of a fiber preform as well as a fiber preform that is formed in accordance with this method are also disclosed. | 02-26-2009 |
20090096119 | Method for Producing Single- or Multi-Layered Fiber Preforms by the TFP Process as Well as a Fixing Thread and Backing Layer - Disclosed is a method for producing single- or multi-layered fiber performs by the TFP process with fiber strands which are aligned substantially such that they are oriented with the flux of force, are laid on at least one backing layer and are attached by at least one fixing thread. After completion of the TFT process, at least one fiber preform is introduced into a fixing device to secure the position of the fiber strands and the fixing threads and/or the backing layers are at least partially removed. As a result of the preferably complete removal of the fixing threads and/or the backing layer from the fiber preform, the latter has virtually ideal mechanical, quasi isotropic properties. In a preferred variant, the fixing threads and/or the backing layers are formed by a water-soluble material, so that they can be completely dissolved by water as the solvent and flushed out. | 04-16-2009 |
20100019405 | Tool for a Resin Transfer Moulding Method - A tool for a resin transfer moulding method comprises a cavity, a resin trap and a transition region, wherein the cavity is designed such that a component can be accommodated in it. Furthermore, the resin trap is integrated in the tool, and the transition region is designed such that with it a connection between the cavity and the resin trap can be established. | 01-28-2010 |

20080210824 | Connecting structure for an aircraft or spacecraft and method for producing the same - The present invention relates to a connecting structure for an aircraft or spacecraft, with a structural component and a stringer. The stringer is connected to the structural component by means of connecting regions. In order to reduce stress peaks that result for example from impact in the structural component, a high impact material is introduced into at least one of the connecting regions to provide a local increase in the energy absorbing capacity of the at least one connecting region. | 09-04-2008 |
20090229761 | Device for producing a fiber preform with virtually any desired surface geometry by the tfp process - Disclosed is a device for producing a fiber preform with virtually any desired surface geometry by the TFP process, wherein a fiber strand can be laid by a guiding device in virtually any desired path curve on a backing layer and the fiber strand can be attached on the backing layer by at least one fixing thread by means of a sewing head. The backing layer can be positioned in an xy direction in relation to the guiding device and the sewing head, wherein the sewing head and/or the guiding device can be positioned in a z direction. As a result of the separation of the positioning capabilities of the backing layer (xy direction) and the guiding device, the sewing head and the lower thread guide (z direction), a relatively simple construction of the device is obtained. By means of the device according to the invention, it is possible, for example, to produce fiber preforms for dome-shaped composite components that are used inter alia as pressure bulkheads for cabins in aircraft with virtually optimum properties. | 09-17-2009 |
