Abstract
The invention relates to an alternative joining method and to the use of the shaped part produced by means of the alternative joining method in drive technology and connection technology.
Description
Alternatives Fügeverfahren Die Erfindung betrifft einen alternatives Fügeverfahren und der Verwendung des mit dem alternativen Fügeverfahren hergestellten Formteils in der Antriebs- und Verbindungstechnik. Alternative Joining Method The invention relates to an alternative joining method and to the use of the molded part produced in the alternative joining method in drive and connection technology.
Es ist bekannt Formteile, wie Reibbeläge und Trägermaterial mit einem Klebstoff, bei- spielsweise ein Reaktivharz, zu versehen und anschließend durch Druck und Temperatur miteinander zu verbinden, wobei durch die Vernetzungsreaktion die Formteile miteinander verbunden werden (DE10201 1018286A1 ). It is known to provide molded parts, such as friction linings and carrier material, with an adhesive, for example a reactive resin, and then to join them together by pressure and temperature, the shaped parts being connected to one another by the crosslinking reaction (DE102011018286A1).
Nachteilig dabei ist, dass zum einen durch den Klebstoff die Handhabung erschwert und der Prozess durch die Härtungsreaktion bei erhöhter Temperatur (>150°C) zeitauf- wendig ist. Zudem bringen Klebstoffe auch Sicherheitsrisiken mit sich. The disadvantage here is that, on the one hand, the handling of the adhesive makes handling more difficult and the process is time-consuming due to the curing reaction at elevated temperature (> 150 ° C.). In addition, adhesives also bring with it safety risks.
Die Aufgabe der vorliegenden Erfindung ist daher, ein alternatives Fügeverfahren bereitzustellen. Die Aufgabe wird durch ein Verfahren zum Fügen von Formteilen, wobei mindestens ein erstes Formteil ein Thermoplast ist und mindestens ein zweites Formteil ein Duroplast oder eine Keramik ist und das zweite Formteil eine strukturierte Oberfläche aufweist, durch folgende Schritte gekennzeichnet: The object of the present invention is therefore to provide an alternative joining method. The object is achieved by a method for joining molded parts, wherein at least one first molded part is a thermoplastic and at least one second molded part is a duroplastic or a ceramic and the second molded part has a structured surface, characterized by the following steps:
a) erstes und zweites Formteil in abwechselnder Reihenfolge gestapelt bereitstellen b) aufbringen einer Flächenpressung und Sonotrode in Ultraschallschwingung versetzen oder Sonotrode in Ultraschallschwingungen versetzen und aufbringen einer Flächenpressung, gelöst. a) provide first and second molded parts stacked in an alternating sequence b) apply a surface pressure and ultrasonically vibrate the sonotrode or ultrasonically vibrate the sonotrode and apply a surface pressure, dissolved.
Durch das Verfahren werden die Formteile miteinander verbunden, ohne dass ein Kleb- stoff benötigt wird. Unter einem Klebstoff wird im Rahmen dieser Erfindung ein Werkstoff verstanden, der Fügeteile durch Fügehaftung und innere Festigkeit verbinden kann (DIN EN 923). Unter der strukturierten Oberfläche wird im Rahmen dieser Erfindung eine Oberfläche verstanden, die eine geeignete Oberflächenstruktur (z.B. Rauigkeit
oder makroskopische Strukturen wie beispielsweise Pyramiden (siehe Figur 1 ) aufweist. Die Rauigkeit wird nach der VDI 3400 12-45 angegeben. Das zweite Formteil weist bedingt durch die Strukturierung als auch die Werkstoffauswahl Reibeigenschaften auf. Mit Hilfe einer Sonotrode, welche durch eine Flächenpressung auf beide Fügepartner (erstes und zweites Formteil) drückt, kommt es in Folge der Schwingung zur Erwärmung der Grenzflächen zwischen den Fügepartnern. The process connects the molded parts without the need for an adhesive. In the context of this invention, an adhesive is understood as meaning a material which can bond joining parts by means of joining adhesion and internal strength (DIN EN 923). In the context of this invention, the structured surface is understood as meaning a surface which has a suitable surface structure (eg roughness or macroscopic structures such as pyramids (see Figure 1). The roughness is given according to VDI 3400 12-45. Due to the structuring as well as the material selection, the second shaped part has frictional properties. With the help of a sonotrode, which presses on both joining partners (first and second shaped part) by a surface pressure, the boundary surfaces between the joining partners heat up as a result of the oscillation.
Durch die strukturierte Oberfläche des zweiten Formteils wird die Energie gebündelt, was zu einer gezielten Erwärmung im ersten Formteil führt. Bedingt durch die Erwär- mung steigt der Dämpfungskoeffizient im ersten Formteil (dem Thermoplast), was zu einer erhöhten inneren Reibung führt und damit mit einem beschleunigten Temperaturanstieg verbunden ist. Beim Überschreiten der Schmelztemperatur des ersten Formteils (Thermoplasts) kommt es zu einem Schmelzefluß in die strukturierte Oberfläche des zweiten Formteils, was zu einem Inneinanderkrallen beider Fügeteile führt. Nach dem Abkühlen und Erstarren der Schmelze sind beide Teile miteinander formschlüssig verschweißt. Durch eine geeignete Wahl der Prozessparameter kommt es zu keiner Beeinträchtigung der Reibeigenschaften der Funktionsfläche. Due to the structured surface of the second molded part, the energy is concentrated, which leads to a targeted heating in the first molded part. As a result of the heating, the damping coefficient increases in the first molded part (the thermoplastic), which leads to increased internal friction and is therefore associated with an accelerated temperature rise. When the melting temperature of the first molded part (thermoplastic) is exceeded, a melt flow occurs in the structured surface of the second molded part, which leads to an inner clawing of the two joining parts. After cooling and solidification of the melt, both parts are welded together form fit. By a suitable choice of the process parameters, there is no impairment of the friction properties of the functional surface.
Vorteilhafterweise wird das Duroplast aus der Gruppe Phenoplasten, duroplastischen Polyurethanen, Epoxiden, duroplastischen Polyestern, Vinylestern und beliebigen Mischungen aus zwei oder mehr der vorgenannten Duroplasten besteht, bevorzugt Phenoplasten oder Epoxide, besonders bevorzugt Phenoplasten ausgewählt. Advantageously, the thermoset is selected from the group consisting of phenolic resins, thermosetting polyurethanes, epoxies, thermosetting polyesters, vinyl esters and any mixtures of two or more of the aforementioned thermosets, preferably phenoplasts or epoxides, more preferably phenoplasts selected.
Vorteilhafterweise wird die Keramik aus der Gruppe der Siliciumcarbide oder der Koh- lenstoffe gewählt. Advantageously, the ceramic is selected from the group of silicon carbides or carbon.
Vorzugsweise weist die strukturierte Oberfläche des zweiten Formteils eine Rauigkeit von Ra: 1 - 100 μπτι, Rk: 4 - 150 μηη, Rpk: 1 - 50 μηη und Rz: 20-300 μηη auf. Ra ist der arithmetische Mittelwert, Rk die Kernrautiefe, Rpk die reduzierte Spitzenhöhe, was einer gemittelten Höhe der aus dem Rauheitskernprofil herausragenden Spitzen bedeutet und Rz die gemittelte Rautiefe. Gemessen wird die Rauigkeit mittels Tastschnittverfahren nach DIN EN ISO 4287:2010.
Bei einer zu geringen Rauigkeit, das heißt, bei Ra <1 μητι, Rk <4 μητι, bei Rpk <1 μηη und Rz < 20 μηη wird der Energieeintrag mittels Ultraschall nicht gebündelt. Dies hat zur Folge, dass das erste Formteil nicht erweicht wird und somit nicht in die Struktur des zweiten Formteils gedrückt werden kann, was wiederum bedeutet, dass eine unzu- reichende Haftung erzeugt wird. Darüber hinaus wird über die Dauer der Ultraschallbehandlung das zweite Formteil zerstört, wobei es sich um einen irreversiblen Prozess handelt. Eine weitere Folge ist, dass aufgrund der zerstörten Oberfläche keine definierten Reibeigenschaften mehr vorhanden sind. The structured surface of the second molded part preferably has a roughness of Ra: 1-100 μm, Rk: 4-150 μm, Rpk: 1-50 μm, and Rz: 20-300 μm. Ra is the arithmetic mean, Rk the kernel roughness, Rpk the reduced peak height, which means an average height of the peaks protruding from the roughness kernel profile, and Rz the average roughness depth. The roughness is measured by means of a stylus method according to DIN EN ISO 4287: 2010. With too low roughness, that is, at Ra <1 μητι, Rk <4 μητι, Rpk <1 μηη and Rz <20 μηη the energy input is not bundled by means of ultrasound. This has the consequence that the first molded part is not softened and thus can not be pressed into the structure of the second molded part, which in turn means that an insufficient adhesion is produced. In addition, over the duration of the ultrasonic treatment, the second molded part is destroyed, which is an irreversible process. Another consequence is that due to the destroyed surface no defined frictional properties are no longer present.
Bei einer zu hohen Rauigkeit, das heißt, bei Ra >100 μιτι, Rk >150 μιτι, bei Rpk >50 μιτι und Rz > 300 μιτι passen die Formteile nicht mehr zusammen und es wird nur eine unzureichende Haftung erreicht. At too high a roughness, that is, at Ra> 100 μιτι, Rk> 150 μιτι, Rpk> 50 μιτι and Rz> 300 μιτι fit the moldings no longer together and it is achieved only insufficient adhesion.
Vorteilhafterweise weist das erste Formteil eine Dicke von <25 mm auf. Advantageously, the first molded part has a thickness of <25 mm.
Bei einer Dicke von mehr als 25 mm ist ein Durchdringen des Ultraschalles unzu- reichend. At a thickness of more than 25 mm penetration of the ultrasound is insufficient.
Vorzugsweise weist das zweite Formteil eine Dicke, von 0,1 - 2,5 mm, bevorzugt 0,2- 1 ,5 mm, besonders bevorzugt 0,3 - 1 mm auf. Preferably, the second molded part has a thickness of 0.1-2.5 mm, preferably 0.2-1.5 mm, particularly preferably 0.3-1 mm.
Bei einer Dicke von kleiner als 0,1 mm wird das Handhabung als auch die Einstellung der Rauigkeit erschwert. With a thickness of less than 0.1 mm, the handling and the adjustment of the roughness is made more difficult.
Vorteilhafterweise wird die Flächenpressung in Schritt b) durch die Sonotrode oder ein Widerlager aufgebracht. Vorteilhafterweise liegt die Flächenpressung im Bereich von 6-60 bar, bevorzugt 10-50 bar, besonders bevorzugt 40-50 bar. Advantageously, the surface pressure in step b) is applied by the sonotrode or an abutment. Advantageously, the surface pressure is in the range of 6-60 bar, preferably 10-50 bar, more preferably 40-50 bar.
Bei einer Flächenpressung von < 6 bar wird keine ausreichende Haftung erzeugt. At a surface pressure of <6 bar, sufficient adhesion is not generated.
Bei einer Flächenkraft von > 60 bar können zwei Effekte auftreten. Zum einen kommt es zu einer Zerstörung des Reibbelages und zum anderen dringt der Reibbelag zu tief und inhomogen in das erste Bauteil ein.
Vorteilhafterweise beträgt die Dauer der Ultraschallschwingungen in Schritt c) bei 0,05 - 3 s, bevorzugt 0,2 - 0,6 s, besonders bevorzugt 0,3 - 0,4 s. With a surface force of> 60 bar, two effects can occur. On the one hand, there is a destruction of the friction lining and on the other hand, the friction lining penetrates too deep and inhomogeneous in the first component. Advantageously, the duration of the ultrasonic vibrations in step c) is 0.05-3 s, preferably 0.2-0.6 s, particularly preferably 0.3-0.4 s.
Bei einer Dauer der Ultraschallschwingungen von < 0,05 s erfolgt kein Erweichen bzw. Anschmelzen des ersten Bauteiles. Es tritt somit nicht der erfindungsgemäße Effekt ei- ner klebstofffreien Haftung auf. Bei > 3s Dauer der Ultraschallschwingungen ist die Prozessstabilität nicht mehr gewährleistet. With a duration of the ultrasonic vibrations of <0.05 s, no softening or melting of the first component takes place. Thus, the effect according to the invention of an adhesive-free adhesion does not occur. At> 3s duration of the ultrasonic vibrations process stability is no longer guaranteed.
Gemäß einer weiteren bevorzugten Ausführungsform ist das zweite Formteil ein faserverstärktes Duroplast oder eine faserverstärkte Keramik. According to a further preferred embodiment, the second molded part is a fiber-reinforced thermoset or a fiber-reinforced ceramic.
Im Rahmen der Erfindung weißt das faserverstärkte Duroplast einen Vernetzungsgrad zwischen 40 und 100 % auf. Bevorzugt zwischen 60-80 %. In the context of the invention, the fiber-reinforced thermosetting plastic has a degree of crosslinking between 40 and 100%. Preferably between 60-80%.
Die Strukturierung der Oberfläche wird hierbei durch eine geeignete Auswahl des Faservolumengehaltes hervorgerufen, welches durch das Verhältnis von Faser zu Matrix beschrieben wird, dem Pressdruck während der Konsolidierung sowie die textile Archi- tektur. The structuring of the surface is in this case caused by a suitable selection of the fiber volume content, which is described by the ratio of fiber to matrix, the pressure during consolidation and the textile architecture.
Unter der textilen Architektur wird im Rahmen dieser Erfindung eine Leinwandbindung oder /und Köperbindung verstanden, wobei als Kett- und Schußgarn ein Zwirn mit einer tex Feinheit von 50-200 verwendet wird. Die Kett- und Schußdichte liegt im Bereich 7- 18 /cm liegen. In the context of this invention, textile architecture is understood to mean a plain weave and / or twill weave, with a twine having a tex fineness of 50-200 being used as the warp and weft yarn. The warp and weft density is in the range 7-18 / cm are.
Vorteilhafterweise beträgt das Faservolumenverhältnis 35-55 %, bevorzugt 40-48%, besonders bevorzugt 44-46 %. Advantageously, the fiber volume ratio is 35-55%, preferably 40-48%, particularly preferably 44-46%.
Vorteilhafterweise wird die Faserverstärkung aus der Gruppe Carbonfasern, Glasfasern, Aramidfasern, hochvernetzte Polymerfasern, Zellulosefasern, Basaltfasern oder Mischungen davon, bevorzugt Carbonfasern ausgewählt wird. Advantageously, the fiber reinforcement is selected from the group of carbon fibers, glass fibers, aramid fibers, highly crosslinked polymer fibers, cellulose fibers, basalt fibers or mixtures thereof, preferably carbon fibers.
Das erfindungsgemäße hergestellte Formteile hergestellt kann als Reibelement in der Antriebs- und Verbindungstechnik verwendet werden.
Vorteilhafterweise liegt die Einsatztemperatur zwischen -20 - 140°C, bevorzugt 10-50 °C, besonders bevorzugt 15-25 °C. Dabei darf für das Einsatzspektrum die Temperatur nicht über dem Schmelzpunkt des ersten Formteiles liegen bei zu niedrigen Temperaturen, d.h. unter der Einsatztemperatur folgt eine Delaminierung bedingt durch die Kalt- sprödigkeit des verfügten Bauteils. The moldings produced according to the invention produced can be used as a friction element in the drive and connection technology. Advantageously, the use temperature between -20-140 ° C, preferably 10-50 ° C, more preferably 15-25 ° C. For the range of applications, the temperature must not exceed the melting point of the first molded part at too low temperatures, ie below the operating temperature a delamination occurs due to the cold brittleness of the assembled component.
