Description
Die Erfindung betrifft ein Verfahren zum Verbinden einer Grundplatte mit einem Stegteil, welcher in die Grundplatte eingesteckt oder eingeschoben beziehungsweise auf der Grundplatte aufgesetzt ist, wobei die Grundplatte mit dem Stegteil im Einsteck-, Einschub- beziehungsweise Aufsetzbereich stoffschlüssig verbunden wird.The invention relates to a method for connecting a base plate with a web portion which is inserted or inserted into the base plate or placed on the base plate, wherein the base plate is materially connected to the web portion in the insertion, insertion or Aufsetzbereich.
Darüber hinaus betrifft die Erfindung eine Verbindung einer Grundplatte mit einem Stegteil, wobei das Stegteil in seinem verbindungsseitigen Endbereich stoffschlüssig mit der Grundplatte verbunden ist.Moreover, the invention relates to a compound of a base plate with a web portion, wherein the web portion is connected in its connection-side end region cohesively with the base plate.
Als Verbindung im Sinne der Erfindung sollen dabei sowohl T-förmige als auch doppel-T-förmige Verbindungen verstanden werden. Bei T-förmiger Verbindung wird das Stegteil mit einer Grundplatte, bei doppel-T-förmiger Verbindung mit zwei Grundplatten verbunden.As a connection in the context of the invention are intended to be understood both T-shaped and double-T-shaped connections. In the case of a T-shaped connection, the web part is connected to a base plate, in the case of a double-T-shaped connection to two base plates.
Stand der TechnikState of the art
Derartige Verbindungen werden in vielfältiger Weise bei verschiedenen Anwendungen, beispielsweise bei der Herstellung von Laufrädern für Ventilatoren, insbesondere für Radialventilatoren, verwendet. Solche Laufräder sollen leicht, insbesondere stabil und verschwindungssteif sein.Such compounds are used in a variety of ways in various applications, for example in the manufacture of impellers for fans, in particular for centrifugal fans. Such wheels should be lightweight, especially stable and disappearing.
Zu diesem Zwecke sind Verbindungen bekannt geworden, bei denen der Stegteil mit einer Grundplatte stoffschlüssig verbunden wird. Dazu wird der Stegteil in eine entsprechende Ausnehmung der Grundplatte eingeführt und mit der Grundplatte verklebt, verschweißt oder durch eine ähnliche stoffschlüssige Verbindungsart mit der Grundplatte formstabil beziehungsweise verwindungssteif verbunden. Derartige Verbindungen können sich jedoch unter Beanspruchung, wie sie beispielsweise beim Betrieb von Radialventilatoren an den Lüfterschaufeln auftreten können, lösen da der Stegteil im Verbindungsbereich mit der Grundplatte die auftretenden Kräfte nicht kompensieren und ableiten kann. Die Formstabilität kann daher nicht gewährleistet werden. Sofern mit einem Ventilator chemisch aggressive Substanzen gefördert werden sollen, besteht auch die Möglichkeit, dass durch diese Substanzen die Kernschicht eines als Mehrschichtplatte ausgebildeten Stegteils beschädigt und somit die Verbindung zwischen Stegteil und Grundplatte, also zwischen Lüfterschaufel und Laufrad, und damit die Belastbarkeit des Ventilators weiter geschwächt wird.For this purpose, compounds have become known in which the web portion is integrally connected to a base plate. For this purpose, the web portion is inserted into a corresponding recess of the base plate and glued to the base plate, welded or connected by a similar cohesive connection to the base plate dimensionally stable or torsionally rigid. Such compounds can, however, under stress, as they can occur, for example, in the operation of centrifugal fans on the fan blades solve because the web portion in the connection area with the base plate can not compensate for the forces and derive. The dimensional stability can therefore not be guaranteed. If chemically aggressive substances are to be conveyed with a ventilator, it is also possible that the core layer of a web part designed as a multilayer plate is damaged by these substances and thus the connection between the web part and the base plate, ie between fan blade and impeller, and thus the load capacity of the fan is weakened.
Weiterhin hat es sich bei dem bekannten Herstellungsverfahren solcher Verbindungen als problematisch erwiesen, wenn mit dem Stegteil zwei Grundplatten verbunden werden sollen, wie es beispielsweise bei einem Lüfterrad für einen Ventilator der Fall ist. Dann ist nämlich der Bereich, in welchem die Verbindung zwischen Stegteil und Grundplatten hergestellt werden soll, insbesondere bei kleinen Abmessungen, wo die beiden Grundplatten nahe beieinander liegen, nur schwer zugänglich, so dass die stoffschlüssige Verbindung nur sehr umständlich herzustellen ist, so dass die Verbindung in der Regel auch sehr uneben ist, was bei den Laufrädern von Ventilatoren auch zu einem ungünstigen Strömungsverhalten des zu fördernden Mediums führt.Furthermore, it has proven to be problematic in the known manufacturing method of such compounds when two base plates are to be connected to the web portion, as is the case for example with a fan for a fan. Then namely the area in which the connection between web portion and base plates to be made, especially in small dimensions, where the two base plates are close to each other, difficult to access, so that the cohesive connection is very cumbersome to produce, so that the connection usually also very uneven, which also leads to an unfavorable flow behavior of the medium to be conveyed in the wheels of fans.
Bekannt sind auch Verfahren zum Verbinden von Mehrschichtplatten, wie sie beispielsweise in der
Problem problem
Aufgabe der vorliegenden Erfindung ist es, das Verfahren bzw. die Verbindung der einleitend genannten Art so zu verbessern, dass eine verwindungssteife beziehungsweise formstabile stoffschlüssige Verbindung des Stegteils und der Grundplatte zustande kommt, die den auftretenden Belastungen bei verschiedensten Anwendungen standhält, wobei die Verbindung in einfacher Weise sauber und ohne großen Aufwand hergestellt werden kann.Object of the present invention is to improve the method and the compound of the aforementioned type so that a torsionally rigid or dimensionally stable cohesive connection of the web portion and the base plate is made, which withstands the loads occurring in a variety of applications, the connection in a simple Way can be made clean and without great effort.

Die Ansprüche 21 bis 23 betreffen Laufräder bzw. Ventilatoren mit Laufrädern, in denen erfindungsgemäße Verbindungen eingesetzt werden.The claims 21 to 23 relate to wheels or fans with wheels, in which compounds of the invention are used.
Dadurch, dass bei dem erfindungsgemäßen Verfahren das Stegteil unter Bildung eines Hohlraums zumindest teilweise ausgehöhlt und der Hohlraum mit einer Füllmasse gefüllt wird, so dass die Füllmasse verbindungsseitig aus dem Stegteil und der Grundplatte herausragt, und dass die im Hohlraum befindliche Füllmasse mit dem Stegteil und die verbindungsseitig aus dem Stegteil herausragende Füllmasse mit der Grundplatte stoffschlüssig und verbindungssteif verbunden wird, ist eine äußerst stabile Verbindung der Grundplatte mit dem Stegteil gewährleistet, die auch größeren Beanspruchungen dauerhaft standhält. Dabei ist die Füllmasse gegenüber aggressiven Substanzen chemisch inert, so dass auch eine druckempfindliche Kernschicht des gegebenenfalls als Mehrschichtplatte ausgebildeten Stegteils nicht mehr angegriffen werden kann, auch wenn sich im Verbindungsbereich zwischen dem Stegteil und der Grundplatte unter größter Beanspruchung die stoffschlüssige Verbindung lösen sollte. Die aggressiven chemischen Substanzen haben dann aufgrund der chemisch inerten Füllmasse im Hohlraum des Stegteils keine Möglichkeit in direkten Kontakt mit der Kernschicht zu gelangen und diese zu beschädigen.Due to the fact that, in the method according to the invention, the web part is at least partially hollowed out to form a cavity and the cavity is filled with a filling compound, so that the filling compound protrudes from the web part and the base plate on the connection side, and that the filling material located in the cavity with the web part and the On the connection side of the web part outstanding filling material is materially and rigidly connected to the base plate, an extremely stable connection of the base plate is ensured with the web part, which withstands even greater stresses permanently. The filling material is chemically inert to aggressive substances, so that even a pressure-sensitive core layer of optionally formed as a multi-layer plate web part can not be attacked, even if the cohesive connection should solve in the connection region between the web portion and the base plate under maximum stress. The aggressive chemical substances have then due to the chemically inert filling in the cavity of the web part no way to get into direct contact with the core layer and damage them.
Für den Fall, dass das Stegteil als Verbindungsteil zweier Grundplatten verwendet wird, wie dies beispielsweise bei einem Laufrad eines Ventilators der Fall ist, lassen sich diese Verbindungen in einfacher Weise herstellen, ohne dass für die stoffschlüssige Verbindung Arbeitsschritte im schwer zugänglichen Bereich zwischen den beiden Grundplatten notwendig sind.In the event that the web portion is used as a connecting part of two base plates, as is the case for example with a fan of a fan, these compounds can be produced in a simple manner, without for the material connection work steps in the difficult to reach area between the two base plates necessary.
Nach einer ersten vorteilhaften Ausgestaltung des erfindungsgemäßen Verfahrens wird als Füllmasse eine Platte verwendet, welche in den Hohlraum innerhalb des Stegteils platziert wird, so dass an der Platte angeordnete Faserstränge mit ihren Enden aus dem Stegteil und der Grundplatte herausragen, und die Platte mit den Fasersträngen, die Faserstränge mit dem Stegteil und die Enden der Faserstränge mit der Grundplatte stoffschlüssig und formstabil beziehungsweise verwindungssteif verbunden werden. Dadurch ist verfahrenstechnisch erreicht, dass die Platte in einfacher Weise in den Hohlraum zwischen den Abdeckplatten eingeschoben werden kann. Da die Platte formstabil ausgebildet ist, kann sie bis zum Ende des Hohlraums durchgeschoben werden, sodass keine die Stabilität des Stegteils negativ beeinflussenden Hohlräume zwischen den beiden Abdeckplatten zurückbleiben.According to a first advantageous embodiment of the method according to the invention is used as a filler filling a plate which is placed in the cavity within the web portion, so that arranged on the plate fiber strands with their ends protrude from the web portion and the base plate, and the plate with the fiber strands, the fiber strands with the web portion and the ends of the fiber strands are bonded to the base plate cohesively and dimensionally stable or torsionally stiff. As a result, procedurally achieved that the plate can be inserted in a simple manner in the cavity between the cover plates. Since the plate is dimensionally stable, it can be pushed through to the end of the cavity, so that no stability of the web part negatively influencing cavities remain between the two cover plates.
Als vorteilhaft hat sich weiterhin erwiesen, dass die Grundplatte und/oder das Stegteil im Einsteck-, Einschub-, beziehungsweise Aufsetzbereich miteinander korrespondierend abgerundet werden. Die Enden der Faserstränge, welche aus dem Stegteil herausragen, erfahren dabei eine besonders schonende Behandlung, da keine Ecken und Kanten vorhanden sind, durch welche die Faserstränge beschädigt werden könnten. Solche Beschädigungen würden die Formstabilität einer nach dem erfindungsgemäßen Verfahren hergestellten Verbindung negativ beeinflussen.It has also proven to be advantageous that the base plate and / or the web part are correspondingly rounded off in the insertion, insertion, or placement area. The ends of the fiber strands, which protrude from the web part, thereby undergo a particularly gentle treatment, since there are no corners and edges, by which the fiber strands could be damaged. Such damage would adversely affect the dimensional stability of a compound prepared by the process according to the invention.
Nachdem die aus dem Stegteil herausragenden Enden der Faserstränge um diese Rundungen herumgeführt worden sind, wird die Grundplatte mit einer Abdeckung versehen, welche stoffschlüssig mit der Grundplatte und der verbindungsseitig aus dem Stegteil herausragenden Füllmasse bzw. den Enden der Faserstränge verbunden. Durch diese Maßnahme ist erreicht, dass die gesamte Füllmasse bzw. die Faserstränge und die Platte effektiv gegen äußere Einflüsse geschützt werden. Die Abdeckung verschließt sozusagen den gesamten Verbindungsbereich auf der dem Stegteil gegenüberliegenden Seite der Grundplatte.After the protruding from the web ends of the fiber strands have been led around these curves, the base plate is provided with a cover which integrally connected to the base plate and the connection side of the web portion outstanding filling material or the ends of the fiber strands. By this measure it is achieved that the entire filling material or the fiber strands and the plate are effectively protected against external influences. The cover closes, so to speak, the entire connection area on the side opposite the web part of the base plate.
Als besonders vorteilhaft hat es sich erwiesen, dass für die Grundplatte, den Stegteil, die Faserstränge und die Platte bzw. die Füllmasse gleiches Material verwendet wird. Die stoffschlüssige und formstabile beziehungsweise verwindungssteife Verbindung der einzelnen Teile kann somit jeweils nach dem gleichen Verbindungsverfahren gegebenenfalls in einem einzigen Arbeits- beziehungsweise Verfahrensschritt hergestellt werden.To be particularly advantageous, it has been found that the same material is used for the base plate, the web portion, the fiber strands and the plate or the filling material. The cohesive and dimensionally stable or rigid connection of the individual parts can thus each according to the same connection method optionally produced in a single work or process step.
Besonders vorteilhaft hat sich dabei erwiesen, dass für die Grundplatte, die Abdeckplatten, die Bänder und die Platte bzw. die Füllmasse Kunststoffe, vorzugsweise Duroplaste oder Thermoplaste, Schichtwerkstoffe beziehungsweise Faserverbundwerkstoffe, insbesondere faserverstärkte, bevorzugt glasfaserverstärkte, kohlenfaserverstärkte beziehungsweise aramidfaserverstärkte Kunststoffe verwendet werden. Diese Materialien zeichnen sich durch eine erhöhte Zug-, Biege- und Druckfestigkeit, Schlagzähigkeit, Formbeständigkeit und Stabilität gegenüber dem Einfluss von Wärme, Säuren, Salzen, Gasen oder Lösungsmitteln bei relativ niedrigem spezifischem Gewicht aus.It has proved to be particularly advantageous that for the base plate, the cover plates, the bands and the plate or the filling material plastics, preferably thermosets or thermoplastics, coating materials or fiber composites, in particular fiber-reinforced, preferably glass fiber reinforced, carbon fiber reinforced or aramid fiber reinforced plastics are used. These materials are characterized by increased tensile, flexural and compressive strength, impact strength, dimensional stability and stability to the influence of heat, acids, salts, gases or solvents at relatively low specific gravity.
Nach einem weiteren Gedanken der Erfindung wird der Stoffschluss zwischen den zu verbindenden Teilen durch Verschweißen, Verkleben und/oder durch Härtung, insbesondere unter Unterdruck beziehungsweise Überdruck und/oder Hitzezufuhr hergestellt. Insbesondere die Verwendung von faserverstärkten Kunststoffen, deren Stoffschluss durch Härtung erzielt wird, hat sich als vorteilhaft erwiesen, da sich die faserverstärkten Kunststoffe im ausgehärteten Zustand leicht bearbeiten lassen, beispielsweise durch Sägen, Drehen, Fräsen, Schleifen, Stanzen oder Bohren.According to a further aspect of the invention, the material connection between the parts to be joined is produced by welding, gluing and / or by hardening, in particular under reduced pressure or overpressure and / or heat input. In particular, the use of fiber-reinforced plastics, the material bond is achieved by curing, has proved to be advantageous because the fiber-reinforced plastics can be easily processed in the cured state, for example by sawing, turning, milling, grinding, punching or drilling.
Bei einer Verbindung mit den Merkmalen des Oberbegriffs des Anspruchs 8 ist das Stegteil in seinem verbindungsseitigen Endbereich zumindest teilweise mit einer formstabilen Füllmasse versehen, welche aus dem Stegteil und der Grundplatte herausragt, wobei die Füllmasse stoffschlüssig mit dem Stegteil und die verbindungsseitig aus dem Stegteil und der Grundplatte herausragende Füllmasse mit der Grundplatte stoffschlüssig und formstabil beziehungsweise verbindungssteif verbunden ist. Dadurch kann die Verbindung auch großen Belastungen standhalten, da in dem Verbindungsbereich die Formstabilität des Stegteils gewährleistet ist. Dort auftretende Belastungen werden durch die formstabile Füllmasse abgeleitet, ohne dass eine gegebenenfalls druckempfindliche Kernschicht des Stegteils beschädigt wird. Die Verbindung zwischen Grundplatte und Stegteil zeichnet sich erfindungsgemäß dadurch aus, dass bei geringem Gewicht eine Formstabilität auch unter großen Belastungen gewahrleistet ist.In a compound having the features of the preamble of
Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist die Füllmasse aus wenigstens einer Platte und Fasersträngen gebildet, wobei die Platte stoffschlüssig und formstabil beziehungsweise verwindungssteif mit den Faserstrangen und die Faserstränge stoffschlüssig und formstabil beziehungsweise verwindungssteif mit dem Stegteil verbunden sind. Solche Verbindungen lassen sich in einfacher Weise herstellen, da die wenigstens eine Platte zusammen mit den Fasersträngen beim Herstellen in einen Hohlraum des Stegteils eingeschoben werden können, ohne dass Hohlräume in dem Stegteil zurückbleiben.According to a particularly advantageous embodiment of the invention, the filling material is formed from at least one plate and fiber strands, wherein the plate are materially and dimensionally stable or torsionally rigid with the fiber strands and the fiber strands cohesively and dimensionally stable or torsionally rigid connected to the web portion. Such compounds can be produced in a simple manner, since the at least one plate together with the fiber strands can be inserted into a cavity of the web part during manufacture without voids remaining in the web part.
Dabei hat sich als vorteilhaft erwiesen, dass die Faserstränge Enden aufweisen, welche stoffschlüssig mit der Grundplatte verbunden sind. Durch diese Maßnahme wird die Verbindung zwischen Grundplatte und Stegteil weiter stabilisiert und gefestigt, da nicht nur der Stegteil stoffschlüssig mit der Grundplatte verbunden sind, sondern auch die Enden der Bänder.It has proved to be advantageous that the fiber strands have ends which are materially connected to the base plate. By this measure, the connection between the base plate and web part is further stabilized and strengthened, since not only the web part are materially connected to the base plate, but also the ends of the bands.
Als besonders vorteilhaft hat sich dabei erwiesen, dass die Grundplatte, der Stegteil, die Faserstränge und die Platte bzw. die Füllmasse aus dem gleichen Material bestehen. Dadurch ist es möglich, die stoffschlüssige und formstabile Verbindung zwischen diesen einzelnen Teilen in gleicher Qualität in gegebenenfalls einem einzigen Arbeits- oder Verfahrensschritt herzustellen.It has proved to be particularly advantageous that the base plate, the web portion, the fiber strands and the plate or the filling material consist of the same material. This makes it possible to produce the cohesive and dimensionally stable connection between these individual parts in the same quality in optionally a single work or process step.
Dabei hat es sich als besonders vorteilhaft erwiesen, wenn die Grundplatte, der Stegteil, die Faserstränge und die Platte bzw. die Füllmasse aus Schichtwerkstoffen oder Kunststoffen, vorzugsweise Duroplasten beziehungsweise Faserverbundwerkstoffen, insbesondere aus glasfaserverstärkten, kohlefaserverstärkten beziehungsweise aramidfaserverstärkten Kunststoffen, bestehen. Dadurch kann die Geometrie der Verbindung zwischen Grundplatte und Stegteil in der gewünschten Weise eingestellt werden und die stoffschlüssige und formstabile beziehungsweise verwindungssteife Verbindung nachfolgend, beispielsweise durch ein Aushärten gegebenenfalls unter Überdruck und/oder Hitzezufuhr, hergestellt werden.It has proved to be particularly advantageous if the base plate, the web portion, the fiber strands and the plate or the filling of layered materials or plastics, preferably thermosets or fiber composites, in particular glass fiber reinforced, carbon fiber reinforced or aramid fiber reinforced plastics exist. Thereby, the geometry of the connection between the base plate and web portion can be adjusted in the desired manner and the cohesive and dimensionally stable or torsionally rigid connection below, for example by curing optionally under pressure and / or heat.
Besonders vorteilhaft ist dabei, dass die Faserstränge als ein, innerhalb des Stegteils die Platte umlaufendes Band ausgebildet sind, dessen Enden stoffschlüssig mit der Grundplatte verbunden sind. Durch diese Maßnahme kann beim Herstellen der Verbindung das Band um die Platte geführt werden und nachfolgend die Platte mit umlaufendem Band in den Hohlraum des Stegteils eingefügt werden. Somit ist die Gefahr, dass Hohlräume in dem Stegteil zurückbleiben, minimiert, da die Platte mit umlaufendem Band vollständig den Hohlraum des Stegteils ausfüllend eingeschoben werden kann.It is particularly advantageous that the fiber strands are formed as a, within the web portion of the plate circumferential band whose ends are materially connected to the base plate. By this measure, when making the connection, the band can be guided around the plate and subsequently the plate with circulating band are inserted into the cavity of the web part. Thus, the risk that cavities remain in the web portion minimized, since the plate with circulating belt can be inserted completely filling the cavity of the web portion.
Um die Verbindung zwischen Grundplatte und Stegteil gegen äußere Einflüsse zu schützen, ist es nach der Erfindung vorgesehen, dass die Enden der Bänder stoffschlüssig mit einer Abdeckung verbunden sind. Einem Eindringen von chemisch aggressiven Substanzen in den Verbindungsbereich ist dadurch vorgebeugt.In order to protect the connection between the base plate and web portion against external influences, it is provided according to the invention that the ends of the bands are integrally connected to a cover. Penetration of chemically aggressive substances in the connection area is prevented.
Auch dabei hat es sich als vorteilhaft erwiesen, wenn die Abdeckung aus dem gleichen Material besteht wie die Bänder, um die Verbindung in gleicher Qualität wie die Verbindung zwischen den restlichen zu verbindenden Teilen zu gewährleisten. Diese Verbindung kann gegebenenfalls in dem gleichen Arbeits- oder Verfahrensschritt hergestellt werden, wie die oben aufgeführten Verbindungen der anderen Einzelteile. Die Abdeckung kann nachfolgend in einfacher Weise bearbeitet werden, so dass optisch eine hochwertige Verbindung entsteht. Again, it has proved to be advantageous if the cover consists of the same material as the bands to ensure the connection in the same quality as the connection between the remaining parts to be joined. If desired, this compound can be prepared in the same working or process step as the compounds of the other components listed above. The cover can be subsequently processed in a simple manner, so that optically creates a high-quality connection.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Grundplatte und der Stegteil im Bereich der stoffschlüssigen Verbindung abgerundet. Dadurch werden Verletzungen der Faserstränge beim stoffschlüssigen Verbinden mit der Grundplatte und dem Stegteil vermieden, da keine Kanten oder Ecken mehr vorhanden sind.According to a further advantageous embodiment of the invention, the base plate and the web portion are rounded in the region of the cohesive connection. As a result, injuries to the fiber strands are avoided in the integral connection with the base plate and the web part, since no edges or corners are no longer present.
Als vorteilhaft hat sich weiterhin erwiesen, dass das Stegteil als eine Mehrschichtplatte, insbesondere als eine Sandwichplatte mit einer Kernschicht und die Kernschicht einschließenden Abdeckplatten, ausgebildet ist. Die Abdeckplatten sind dabei widerstandsfähiger gegen äußere Einflüsse ausgebildet als die Kernschicht und bieten der Kernschicht einen gewissen Schutz.It has furthermore proved to be advantageous that the web part is designed as a multilayer plate, in particular as a sandwich plate with a core layer and cover plates enclosing the core layer. The cover plates are designed to be more resistant to external influences than the core layer and provide the core layer some protection.
Damit die Verbindung in ihrer Gesamtheit ein relativ geringes Gesamtgewicht aufweist, ist es vorgesehen, dass die Kernschicht aus einem Schaumstoff besteht.So that the compound in its entirety has a relatively low total weight, it is provided that the core layer consists of a foam.
Vorteilhafterweise ist dieser Schaumstoff als Hartschaumstoff ausgebildet, welcher druckwiderstandsfähiger ist als normaler Schaumstoff. Somit ist die Stabilität der Verbindung nochmals erhöht, da auch Belastungen auf die Mehrschichtplatte durch den Hartschaumstoff besser abgefangen werden.Advantageously, this foam is designed as rigid foam, which is more pressure-resistant than normal foam. Thus, the stability of the compound is increased again, as well as stress on the multilayer board are better absorbed by the rigid foam.
Dabei hat es sich als vorteilhaft erwiesen, dass die Abdeckplatten aus einem druckwiderstandsfähigen Material bestehen. Dadurch ist insbesondere eine druckempfindliche Kernschicht vor äußeren Einflüssen wirkungsvoll geschützt.It has proven to be advantageous that the cover plates made of a pressure-resistant material. As a result, in particular a pressure-sensitive core layer is effectively protected against external influences.
Weiterhin betrifft die Erfindung auch ein Laufrad für Ventilatoren, insbesondere Radialventilatoren, mit einer Mehrzahl von aus Mehrschichtplatten bestehenden Lüfterschaufeln, wobei die Lüfterschaufeln durch ein erfindungsgemäßes Verfahren der Grundplatte des Laufrades verbunden sind.Furthermore, the invention also relates to an impeller for fans, in particular centrifugal fans, with a plurality of fan blades consisting of multilayer plates, wherein the fan blades are connected by an inventive method of the base plate of the impeller.
