摘要:
The invention relates to a method for producing a support structure in the form of a hybrid component with a base structure and with at least one reinforcement structure, having the following steps: producing the at least one reinforcement structure for each base structure, wherein the at least one reinforcement structure, in particular all of the reinforcement structures, is/are made of a composite material comprising fibers and a matrix using a pultrusion and/or extrusion process, and a pultrusion unit and/or an extrusion unit in the form of a PE machine (42) is moved in space in order to produce the reinforcement structure such that the at least one reinforcement structure, in particular all of the reinforcement structures, is/are pultruded and/or extruded onto the base structure at the respective required connection position after the pultrusion and/or extrusion process in order to provide the base structure using a G machine (41); and connecting the at least one reinforcement structure to the base structure such that the at least one reinforcement structure is connected to the base structure in a connection position, and the base structure together with the at least one reinforcement structure forms the support structure. The support structure is to be producible with little technical and financial expenditure. This is achieved in that the method is carried out using a machine system (40); in the machine system (40), the number of the at least one G machine (41) and the number of the at least one PE machine (42) are different; and the base structure (4) provided by the at least one G machine (41) is transported to the at least one PE machine (42) using a conveyor system (43).

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Kraftfahrzeughybridbauteils (1) sowie ein erfindungsgemäß hergestelltes Kraftfahrzeughybridbauteil (1), welches sich dadurch auszeichnet, dass ein Grundkörper aus metallischem Werkstoff hergestellt ist und mit einem Verstärkungspatch (8) aus Faserverbundwerkstoff verstärkt wird. Zusätzlich weist der Verstärkungspatch (8) eine metallische Lage (10) auf, die die Bauteilfestigkeit erhöht, bei annähernd gleichbleibendem spezifischem Eigengewicht.

In order to allow the in-situ manufacture of a protective liner for an elongated finished structural part (14), it is proposed to mechanically attach a sealant mold portion (20) to the elongated finished structural part (14), specifically the surface (18) to be protected. The sealant mold portion (20) in cooperation with the elongated finished structural part (14) forms a mold cavity (22) which gets injected with a wet sealant (28). The wet sealant (28) cures into a cured sealant member (30) which is bonded to the surface (18) and acts as a protective liner.

The invention relates to a method for the further processing of a product (30) prefabricated preferably in large quantities, wherein the product has a surface (31) for an additive multi-dimensional material application. Information for the additive multi-dimensional material application are entered into a device, in which the additive multidimensional material application is digitized from said information and broken down into elements that are suitable for the additive application of the material application on the surface (31). The prefabricated product (30) is introduced into a device (I) for additively applying the material application, in such a way that the elements for the additive multi-dimensional material application on the surface (31) are joined according to the information by means of an additive production method. Because the surface is an individualization surface (31) of the prefabricated product and the additive material application is a multi-dimensional individualization that is intended and suitable for individualizing the product, and because at least one of the prefabricated products is identified and individually provided with the multi-dimensional individualization (32) by means of the information, a method by means of which products prefabricated in larger quantities can be further processed, individualized, or personalized according to individual wishes is provided. The prefabricated product (30) is equipped with an associated information carrier for holding the information regarding the individualization in order to support the method process.
摘要:
Packaging containers (e.g., cups) or protective wraps may be made with two layers of sheet material and an expanded thermal insulation between the layers. The thermal insulation may be made from microencapsulated, heat-expandable particles that are expanded with a microwave heater at some point during processing substrate, building, conveying or packaging the containers. The particles may be applied to blanks formed from die cutting, expanded by heating, and then tampered. The blanks may be outer wraps to a double wall cup, formed by placing and adhering an inner cup to the outer wrap. Alternatively, an adhesive containing the particles are applied to inner cups, which may be adhered to outer wraps to complete formation of the double wall cups. The cups may then be heated with a microwave heater at a subsequent workstation as the cups are conveyed, stacked, placed in bags, the bags in cartons and the cartons stacked and palletized.
