摘要:
The plastic molded part and the construction structure have a carrying structure (3) encompassed partially or fully by a polymer material (8) defining the molded part. The carrying structure (3) comprises multiple interconnected, high-strength structural elements (5) reinforced with filaments. This allows the production of embodiments having varying shapes such as containers, tanks, vehicle cells, etc., at reduced complexity and cost.
摘要:
The present invention relates to a method for connecting a surface-structured workpiece (1) and a plastic workpiece (7) using a joining tool including a sonotrode (9), said surface-structured workpiece (1) comprising a structured contact surface section (3), said structured contact surface section (3) comprising pin-like elements (5) extending away from the structured contact surface section (3), said method comprising the following steps: Positioning the surface-structured workpiece (1) and the plastic workpiece (7) on an anvil (11) such that the structured contact surface section (3) faces a contact surface (13) of the plastic workpiece (7), Positioning the joining tool on the metal workpiece (1) so as to bring the sonotrode (9) into contact with an outer surface (15) of the metal workpiece (1), the outer surface (15) being opposite to the structured contact surface section (3), Applying a pressure (17) to the sonotrode (9) and/or the anvil (11) perpendicular to the contact surface (3, 13) to hold the workpieces (1, 7) fixed between the anvil (11) and the sonotrode (9) and applying ultrasonic vibrations (19) to the workpieces (1, 7) by the sonotrode (9) for a predetermined period of time, so that softening of the plastic workpiece (7) is induced and the pin-like elements (5) penetrate into the plastic workpiece (7).
摘要:
Es wird ein Knotenelement (1a..1f) aus faserverstärktem Kunststoff (2) mit wenigstens drei rohrförmigen und/oder profilförmigen Anschlussbereichen (A..F) angegeben, das zumindest ein V-förmiges oder U-förmiges, starres Wandelement (3a, 3b) aufweist, welches zwischen zwei Anschlussbereichen (A..B, C..D) angeordnet und mit dem faserverstärkten Kunststoff (2) verbunden ist. Weiterhin wird ein Herstellungsverfahren für ein solches Knotenelement (1a..1f) angegeben, bei dem ein V-förmiges oder U-förmiges Wandelement (3a, 3b) auf einem Positivkern (5a..5c) angeordnet wird, die entstandenen Anordnung mit Fasern umwickelt wird und das Knotenelement (1a..1f) nach Einbringen beziehungsweise Aufbringen eines vernetzenden Kunststoffs schließlich ausgehärtet wird. Zudem wird eine Verwendung eines Knotenelement (1a..1f) im Rahmenbau oder Leitungsbau angegeben.
摘要:
Structural panels for use in manufacturing fuselage bodies and other aircraft structures are disclosed herein In one embodiment, a monolithic integrated structural panel is configured to include a skin, an array of stiffeners and an array of frames which are preferably arranged in a mutually orthogonal layout, without the need of cut-outs in any of the crossing elements, the frame and stringer members having continuous flanges and spliced webs.

Structural panels for use in manufacturing fuselage bodies and other aircraft structures are disclosed herein. In one embodiment, a monolithic integrated structural panel is configured to include a skin, an array of stiffeners and an array of frames which are preferably arranged in a mutually orthogonal layout, without the need of cut-outs in any of the crossing elements. One advantage of the disclosed embodiments is that the frame and stringer members have continuous flanges and spliced webs. The disclosed embodiments herein are compatible with composite materials technology, offering another advantage, namely the possibility of manufacturing integrated products in a single cure (“one-shot”) cycle. A structure of composite materials, e.g. carbon fiber reinforced plastics, typically comprises a skin panel, reinforced by frame and stringer members. A monolithic integrated structure constructed in accordance with the disclosed embodiments is well-suited for use as a portion of an aircraft structure, for example an aircraft fuselage, wing or empennage.
