Abstract:
Die Erfindung betrifft ein Verfahren zum Herstellen eines selbsttragenden Karosserieaußenteils (10), insbesondere für einen Kraftwagen, bei welchem ein aus einem expandierten Polypropylen-Partikelschaumstoff hergestelltes Verstärkungsteil (14) mit einem Außenverkleidungsteil (12) des Karosserieaußenteils (10) gefügt wird, wobei das Verstärkungsteil (14) und das Außenverkleidungsteil (12) zuerst in separaten Fertigungsschritten hergestellt werden und erst danach das Verstärkungsteil (14) mit dem Außenverkleidungsteil (12) gefügt wird.
Abstract:
The present invention regards an aircraft structure comprising an aerodynamic composite shell (7), the interior face (9) of which in whole or in part is bonded with at least one two- or three-dimensional structural composite part (11) by means of a bonding material (15). It also regards a method of manufacture of the aircraft structure. The bonding material (15) comprises a non-structural fiber reinforced resin system, wherein at least one portion of the bonding material, which portion spatially corresponds with an interior face filling volume (21), is thicker than other portions of the bonding material (15), due to settlement of resin of the non-structural fiber reinforced resin system in said interior face filling volume (21) during the viscous phase of the curing of the non-structural fiber reinforced resin system.
Abstract:
A straight joint and method for connecting two adjacent construction elements, such as sandwich panels, so as to reduce or minimize thermal bridging across the elements. The sandwich panels each have a core, an outer layer, a cavity defined by a portion of the core, and a pathway through the outer layer to the cavity. The panels are erected such that the panel cores are in contact with one another. Bonding material is injected into the cavity through the pathway to seal the joint and maintain the panels in fixed relation to one another.
Abstract:
A composite laminate is made by providing at least a first composite ply and a second composite ply, each having longitudinally oriented fibers in a thermoplastic matrix. The second composite ply is disposed on, and in transverse relation to, the first composite ply. Preferably, the second ply is disposed at 90° relative to the first ply. An article can be manufactured by providing a core material and applying a reinforcing material to a portion of the core material. The reinforcing material is a reinforcing composite ply or a composite laminate as described herein. Optionally, the core material is a prepreg that may be a composite laminate.
Abstract:
The present invention relates to a method of joining at least two parts by adhesion, said method comprising arrangement of a porous layer in the adhesive joint for taking up excess adhesive from the adhesive joint as such. The invention further relates to an element - including in particular a blade for a wind turbine - which is combined by adhesion of several parts, and wherein a porous layer is at least partially comprised in the adhesive joint between the parts and take up excess adhesive outside the adhesive joint. The porous layer may be of a mesh-like structure or may have the structure of a sponge and may furthermore be entirely or partially pre-impregnated with adhesive.
Abstract:
The surface of a moulding tool (9), for receiving a first aircraft component, for example a spar (3), is shaped to correspond to the surface of a second aircraft component, for example a wing skin (5). A gap is defined between the tool (9) and the first component. Resin is drawn into the gap by a suction pump. The resin fills the gap and cures to form a shim (6). The first and second components, which are in the form of composite material structures, are then joined together without any significant voids being formed therebetween.
Abstract:
An area (30) of a composite laminate structure (44) is reworked by scarfing the area, generating a 3-D map of the scarfed area, and installing a rework patch (32) that is built based on the 3-D map.
Abstract:
Verfahren und Presswerkzeug (100) zur Herstellung von Hybridbauteilen (200), die aus einem räumlich geformten Blechmaterial und einem faserverstärkten Kunststoffmaterial gebildet sind. Das Verfahren fasst die folgenden Schritte um: • Bereitstellen eines räumlich geformten Blechmaterials (210); • Bereitstellen eines Fasermaterial (221) enthaltenden Vorformlings (220); • Aufbringen eines Klebstoffs (230) auf das Blechmaterial (210) und/ oder auf den Vorformling (220) und Fügen der Materialien zu einem Verbund, wobei der Klebstoff (230) bezüglich der Außenkontur des Vorformlings (220) einen überstehenden Klebstoffrand (231) bildet; und • Verpressen des Verbunds in einem Presswerkzeug (100), wobei im Bereich des überstehenden Klebstoffrands (231) eine Verunreinigung des Blechmaterials (210) mit Harzmaterial verhindert wird.
Abstract:
The invention relates to a method for joining a first composite structure (la, lb) to at least a second structure (1a, 1b) comprising the steps of: providing a hole in the first composite structure (S100, S200), providing a hole in the at least one second structure (S100, S200), arranging a resin comprising fiber-like electrically conducting and mechanically reinforcing nano elements in the space between a hole surface of the first composite structure and the fastening element (S120, S210) and/or on the fastening element, arranging a fastening element in the hole of the first composite structure and into the hole of the at least one second structure so that the fastening element extends in the first composite structure and into the at least one second structure (S110, S220), the step of arranging the resin proceeds the step of arranging the fastening element in the holes or vice versa, curing of the resin (s130, S230). The invention also relates to a joint comprising a first composite structure (1a, 1b), at least a second structure (1a, 1b) and a fastening element (4) extending in a hole in the first composite structure and into a hole of the at least second structure wherein a plastic material comprising fiber-like nano elements (3) is arranged in a space between the fastening element (4) and a hole surface of at least the first composite structure.
