Abstract:
The present invention relates to a moulded plastic article provided with a vibration damping member, said member being formed from a vibration damping laminate comprised of a constrained viscoelastic layer (50) sandwiched between two rigid constraining metallic layers (40), which member is moulded into the article when moulding the article. The invention also relates to a method of preparing such plastic article by means of moulding.
Abstract:
A fibre reinforced polymer (FRP) composite structure incorporates a woven preform containing tows of carbon or other advanced fibres (1, 3) and wires (2, 4) of shape memory alloy (SMA). The SMA wires are capable of absorbing much larger amounts of strain energy than the conventional components of FRP composites and hence enhance the impact resistance of the structure. The woven form incorporates the SMA into the structure in an optimum manner in terms of handling and performance.
Abstract:
The invention relates to a noise-insulating composite part and to a method for the production thereof. Said composite part (38) is specifically designed for motor vehicles and comprises a solid layer (6) and a noise attenuating layer (17) which is connected thereto and which is made of porous and/or textile material. The solid layer is embodied as a moulded part by extruding a plasticified synthetic material, which is selected from the group of thermoplastic elastomers, provided in a continuous casting method. Said solid layer has areas which have various thicknesses and/or densities and is only partially welded to the noise attenuating layer (17). The noise attenuating layer comprises a profiled structure formed by thermal reshaping and the periphery of the noise attenuation layer (17) overlaps with the periphery of the solid layer (6) at least in sections.
Abstract:
Die Erfindung betrifft einen Schallabsorber, insbesondere für Kraftfahrzeuge, sowie ein Verfahren zu dessen Herstellung. Der Erfindung liegt die Aufgabe zugrunde, ein akustisch wirksames Bauteil für Kraftfahrzeuge zu schaffen, das neben einer hohen schallabsorbierende Wirkung auch eine hohe Temperaturbeständigkeit sowie ein hohes Rückstellvermögen bei Druckbeaufschlagung aufweist. Zur Lösung dieser Aufgabe wird ein Schallabsorber vorgeschlagen, der aus einem offenporigen, aus Korkpartikeln und wärmereaktivem Bindemittel hergestellten Formteil (7) gebildet ist, wobei der Anteil des Bindemittels am Formteil (7) maximal 1 bis 20 Gew.-% beträgt. Die Herstellung des Schallabsorbers erfolgt erfindungsgemäss in der Weise, dass die Korkpartikel mit dem wärmereaktivem Bindemittel in einen Hohlraum (4) eines nach Art eines Spritzgiesswerkzeuges gestalteten Formwerkzeuges eingebracht werden. Die Abbindung des Bindemittels wird vorzugsweise dadurch ausgelöst, dass das Bindemittel im Hohlraum (4) des Formwerkzeuges (1) mit Wasserdampf (20) beaufschlagt wird.
Abstract:
The invention relates to a sound absorber (A), especially for motor vehicles, comprising a layer (4) of absorption material, such as open-pored or optionally closed-pored foamed material or a wood fibre composite, and a top layer (5). The aim of the invention is to produce an absorber in such a way that said absorber is easy to produce and assemble and functions well. According to the invention, the top layer (5) for leading through a loom of cables (8) or the like is provided with a tubular recess (40) for leading through a loom of cables. Said recess (40) is provided with groove-like undercuts (42) on the outside.
Abstract:
Fiber-reinforced resin pipe (10) fittings have a structural pipe wall (12) formed from helically wound reinforcing fiber that is bonded together with a polymer resin. An intermediate layer (16) is disposed around the structural pipe wall, and a fiber-reinforced resin layer (18) is disposed around the intermediate layer. The intermediate layer is formed from material selected from the group consisting of impact attenuating and impact absorbing materials. The fiber-reinforced resin layer comprises layers of helically wound reinforcing fiber bonded together with a polymer resin. The materials selected to form the fiber-reinforced resin layer can be the same or different from that used to form the structural pipe wall. The pipe may comprise a single intermediate and fiber-reinforced layer disposed around the structural pipe wall, or may comprise an impact resistant jacket disposed around the structural pipe wall, wherein the jacket is made up of alternating intermediate and fiber-reinforced resin layers. Fiber-reinforced resin pipes, constructed according to the principles of this invention, have improved impact resistance when compared to conventionally constructed fiber-reinforced resin pipes.
