Description
Kunststoffbauteile der hier betroffenen Art werden in vielfacher Form, Größe und Gestalt, z.B. als Halbzeuge, hergestellt. Im eingebauten Zustand sind sie Belastungen ausgesetzt, die lokal stark schwanken können. Ziel der vorliegenden Erfindung ist es, Kunststoffbauteile herzustellen, die den unterschiedlichen Belastungen Rechnung tragen.Plastic components of the species affected here are in many forms, sizes and shapes, e.g. produced as semi-finished products. They are in the installed state Exposed to loads that can fluctuate greatly locally. aim The present invention is to produce plastic components that take the different loads into account.
Aus der europäischen Patentschrift 370 342 ist es bekannt, Kunststoffbauteile herzustellen, die aus einem Grundkörper aus Metall- oder Kunststoffblech sowie Verstärkungsrippen bestehen. Die gegenseitige Befestigung der Bauelemente erfolgt über diskrete Verbindungsstellen. Hinweise auf zusätzliche lokale Verstärkungen, die lokal erhöhten Belastungen standhalten sollen, enthält die genannte Schrift nicht.Out the European Patent 370 342 it is known to produce plastic components, the one body consist of metal or plastic sheet and reinforcing ribs. The mutual attachment of the components is done via discrete Joints. Indications of additional local reinforcements, the locally elevated The document mentioned does not contain stresses.
Es ist weiterhin bekannt, Kunststoffbauteile, die durch Spritzgießen, Pressen o.ä. Verfahren hergestellt werden, in Bereichen, in denen erhöhte Belastungen zu erwarten sind, mit Glasfaserverstärkungen auszurüsten. Insbesondere im Hinblick darauf, dass die Komplexität der Geometrien der hier betroffenen Kunststoffbauteile ständig zunimmt, ist es häufig nicht mehr möglich, die zur Herstellung der Bauteile notwendigen Werkzeuge in faserverbundgerechter Form auszubilden. Die Orientierung der Glasfasern ist in Bezug auf die auftretenden Kräfte nicht optimiert. Veränderte Einlagen des Materials oder verfahrenstechnische Variationen, die diesen Mangel beheben, sind nicht möglich.It is also known plastic components by injection molding, pressing etc. method are manufactured in areas where increased loads are expected are, with glass fiber reinforcements equip. Especially in view of the complexity of the geometries of the plastic components affected here is constantly increasing, it is often not more is possible, the tools required to manufacture the components in a fiber-compatible manner Form. The orientation of the glass fibers is related to the forces that occur not optimized. changed Deposits of the material or procedural variations that this deficiency is not possible.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, Kunststoffbauteile der hier betroffenen Art in Bereichen mit erhöhter Belastung mit Glasfasereinliegern auszurüsten, die in Bezug auf ihre Lage und die Orientierung der Glasfasern optimiert sind.The The present invention has for its object plastic components of the type affected here in areas with increased exposure to glass fiber inserts equip, which optimizes in terms of their location and the orientation of the glass fibers are.
Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale der Patentansprüche gelöst.According to the invention Object achieved by the characterizing features of the claims.
Die Erfindung erlaubt es, fließtechnisch und prozessoptimierte Kunststoffbauteile herzustellen, die gezielt in Bereichen mit höheren Belastungen höhere Festigkeiten und Steifigkeiten aufweisen. Der Einlieger ist integrierter Bestandteil des Gesamtbauteiles. Da der Einlieger selbst in einem unabhängigen Werkzeug hergestellt wird, bestehen die bereits erwähnten Optimierungsmöglichkeiten. Selbst Kunststoffbauteile mit äußerst komplexen Geometrien können gezielt mit einer oder mehreren optimierten Verstärkungen ausgerüstet werden, was bis heute nicht – oder zumindest nicht ohne erheblichen technischen Aufwand – möglich war.The Invention allows flow technology and to manufacture process-optimized plastic components that are targeted in areas with higher Loads higher Have strength and rigidity. The granny is more integrated Part of the overall component. Since the granny himself in one independent tool is produced, there are the optimization options already mentioned. Even plastic components with extremely complex Geometries can specifically with one or more optimized reinforcements equipped become what is not - or at least not without considerable technical effort - was possible.
Ergebnis des erfindungsgemäßen Verfahrens sind Kunststoffbauteile, die eine Endlosglasfaserverstärkung in ihren Belastungsrichtungen über ein endlosglasfaserverstärktes Bauteil mit gleicher oder ähnlicher Matrix aufweisen. Der Vorteil dieses Verfahrens liegt im Einsparen von einem eventuell benötigten Metalleinleger mit den entsprechenden Bauteilkosten und Investitionskosten für dieses Metallbauteil. Ein Korrosionsschutz kann entfallen. Ein weiterer Vorteil sind die erheblich verbesserten Recyclingmöglichkeiten eines Bauteils mit der Endlosglasfaserverstärkung, das ohne zusätzliche metallene Verstärkungselemente auskommt. Auch ist es ein Vorteil, dass das endlosglasfaserverstärkte Bauteil in dem weiteren Bauteil als biegesteifes Bauteil eingelegt werden kann, was das gesamte Handling, die Industrialisierung und die Automatisierung wesentlich vereinfacht. Es ist auch ein Vorteil, dass Kunststoffteile im Vergleich zu gleich großen, ähnlich gestalteten Bauteilen eine bessere Dimensionsstabilität und kleinere Toleranzen aufweisen, was in diesem Zusammenhang die Herstellung von Strukturbauteilen mit tragenden Funktionen dadurch erleichtert, dass sich dieses vorgefertigte endlosglasfaserverstärkte Bauteil wesentlich leichter in ein entsprechendes Werkzeugkonzept für ein größeres weiteres Bauteil integrieren lässt. Auch ist ein Vorteil, dass beim Einsatz eines verstärkten Kunststoffbauteiles bei Änderungen an dem großen Bauteil nur Änderungen an einem weiteren Bauteil geschehen müssen, während bei entsprechenden Stahlbauteilen die Änderungen meistens mehrere Verbundwerkzeuge betreffen, was solche Änderungen maßgeblich preislich und terminlich beeinflusst. Ein weiterer Vorteil im Vergleich zu entsprechenden Hybridbauteilen ist, dass die Anbindung von Rippen zwischen dem Grundkörper und dem Schalenkörper nicht in verschiedenen diskreten Verbindungen stehen oder über Durchbrüche sondern durch eine direkte Anbindung der Matrixen der verschiedenen Bauteile geschehen kann.Result of the method according to the invention are plastic components that have a continuous glass fiber reinforcement in their directions of stress over a endless glass fiber reinforced Component with the same or a similar one Have matrix. The advantage of this method is that it saves money of a possibly needed one Metal insert with the corresponding component costs and investment costs for this Metal component. Corrosion protection can be omitted. Another The advantage is the significantly improved recycling options a component with the continuous glass fiber reinforcement, which without additional metal reinforcement elements gets along. It is also an advantage that the continuous glass fiber reinforced component be inserted in the further component as a rigid component can do all the handling, industrialization and automation much simplified. It is also an advantage that plastic parts compared to similarly sized, similarly designed Components have better dimensional stability and smaller tolerances, which in this context involves the manufacture of structural components supporting functions is facilitated by the fact that this is prefabricated continuous glass fiber reinforced component much easier in a corresponding tool concept for a larger one Component can be integrated. It is also an advantage that when using a reinforced plastic component in case of changes on the big one Component only changes must be done on another component, while corresponding steel components the changes mostly Several composite tools affect what such changes are significant influenced in price and time. Another advantage in comparison to corresponding hybrid components is that the connection of ribs between the base body and the shell body not in different discrete connections or through breakthroughs but through a direct connection of the matrixes of the different components can happen.
Schließlich liegt ein weiterer Vorteil der Erfindung darin, dass die Herstellung des Gesamtbauteils im zweiten Werkzeug ohne weiteres durch Pressen erfolgen kann. Die Gefahr, dass der Pressvorgang die optimale Lage der Endlosfasern nachteilig verändert, besteht nicht mehr. Die Erfindung vereinfacht die Herstellung von Bauteilen mit lokalen Endlosfaserverstärkungen mit sehr komplexen Geometrien erheblich.Finally lies Another advantage of the invention is that the manufacture of the Entire component in the second tool easily done by pressing can. The risk that the pressing process the optimal location of the continuous fibers adversely changed does not exist anymore. The invention simplifies the manufacture of Components with local continuous fiber reinforcements with very complex Geometries considerably.
