Abstract
Description
Die Erfindung betrifft ein Karosserieelement aus einem transparenten Kunststoff mit den Merkmalen des Patentanspruchs 1.The The invention relates to a body element made of a transparent Plastic with the features of claim 1.
Bei der Konstruktion von Fahrzeugkarosserien tritt häufig das Problem auf, dass ausgehend von einer Fahrerposition bestimmte Bereiche der Umgebung durch tragende Bauteile, verdeckt werden. Insbesondere die A-Säule, die einerseits die Windschutzscheibe einrahmt und andererseits den Rahmen für die vorderen Türen bildet, stellt teilweise eine erhebliche Sichtwinkelverdeckung für den Fahrer dar. Ferner können auch die B-Säule, die zwischen der vorderen und der hinteren Tür angeordnet ist und die C-Säule können beim Seitenblick beziehungsweise beim Rückwärtsfahren sichtverdeckend wirken.at The construction of vehicle bodies often encounters the problem that certain areas of the environment starting from a driver's position be covered by load-bearing components. In particular, the A-pillar, the on the one hand framed the windshield and on the other hand the frame for the front doors partially represents a significant Sichtwinkelverdeckung for the driver. Furthermore, can also the B-pillar, which is located between the front and the rear door and the C-pillar can Side glance or visibly opaque when reversing.
Das
Deutsche Gebrauchsmuster DE-GM 14 73 527 regte aus diesem Grund
bereits an, tragende Karosserieelemente, wie gerade die A-, B-,
oder C-Säule
aus einem transparenten Kunststoff herzustellen. Der hierin allgemein
offenbarte transparente Kunststoff ist jedoch nicht geeignet, den
modernen Anforderungen an eine Crash-Sicherheit zu genügen. Das
Als Glasfüllstoffe werden hier unter anderem Glasfasern genannt, die eine Länge bis zu 30 mm aufweisen. Derartige Glasfasern können bei flächigen Bauteilen in gewisser Weise eine Verstärkung hervorrufen, die so hergestellten Bauteile sind jedoch nicht als tragende Strukturelemente geeignet. Ferner weisen derartige Bauteile eine vergleichsweise geringe Kriechbeständigkeit auf.When glass fillers are here among other glass fibers called, which are a length to to 30 mm. Such glass fibers can in flat components in some Way amplify, However, the components produced in this way are not as load-bearing structural elements suitable. Furthermore, such components have a comparatively low creep resistance on.
Die Aufgabe der Erfindung besteht darin, ein tragendes Bauteil einer Fahrzeugkarosserie in der Art transparent auszugestalten, dass es einerseits die nötige Festigkeit und Steifigkeit im Crashfall aufweist und gleichzeitig eine hohe Kriechbeständigkeit aufweist.The The object of the invention is a supporting component of a Vehicle body in the way transparent to design that it on the one hand the necessary Strength and rigidity in the event of a crash and at the same time has a high creep resistance.
Die Lösung der Aufgabe besteht in einem Karosserieelement mit den Merkmalen des Patentanspruchs 1.The solution The task consists in a body element with the features of claim 1
Das erfindungsgemäße Karosserieelement besteht aus einem transparenten, faserverstärkten Verbundkunststoff. Der Verbundkunststoff weist eine thermoplastische oder eine duroplastische Polymermatrix auf. Die Fasern, die in die Matrix eingebettet sind, sind Glasfasern, wobei diese in Form von unidirektionalen bevorzugt Langfasern oder Endlosfasern ausgestaltet sind. Ferner sind die Glasfasern mit einer Schlichte versehen und zur Wahrung der Transparenz des Kunststoffes beträgt der Unterschied der Brechungsindizes der Glasfasen und der Polymermatrix weniger als 0,05.The body element according to the invention consists made of a transparent, fiber-reinforced composite plastic. Of the Composite plastic has a thermoplastic or a thermosetting Polymer matrix on. The fibers embedded in the matrix are glass fibers, these being preferred in the form of unidirectional Long fibers or continuous fibers are designed. Furthermore, the Glass fibers provided with a size and to ensure transparency of the plastic is the difference of the refractive indices of the glass fibers and the polymer matrix less than 0.05.
Für eine gute optische Transparenz des Karosserieelementes ist es zudem von Bedeutung, dass die Fasern unidirektional ausgerichtet sind. Hierunter wird verstanden, dass einzelne benachbarte Faserfilamente, die nebeneinander verlaufen und gegebenenfalls zu einem Faserstrang zusammengefasst sind, eine möglichst gleichmäßige parallele Ausrichtung aufweisen.For a good optical transparency of the body element, it is also important that the fibers are unidirectionally aligned. This is understood to mean that individual adjacent fiber filaments run side by side and optionally combined into a fiber strand, a preferably even parallel alignment exhibit.
Gleichwohl können in einem Bauteil Fasern oder Faserstränge in unterschiedliche Richtungen ausgerichtet sein.nevertheless can aligned in one component fibers or fiber strands in different directions be.
Der Begriff Langfaser ist durch die unterschiedlichen Herstellungsverfahren variabel definiert. Bei einem Extrusionsverfahren werden Fasern ab einer Länge von 8 mm als Langfasern bezeichnet. Bei einem Pultrusionsverfahren ist die Länge der Fasern durch die Bauteilgeometrie vorgegeben (ab 50 mm). Der Begriff Endlosfasern bedeutet hierbei, dass die Fasern von einer Rolle in eine, dem Bauteil entsprechende Form gewickelt oder gelegt werden.Of the Term long fiber is due to the different manufacturing processes variably defined. In an extrusion process fibers become from one length of 8 mm referred to as long fibers. In a pultrusion process is the length the fibers given by the component geometry (from 50 mm). Of the Term continuous fibers here means that the fibers of a Roll in one, the component corresponding shape wound or laid become.
Die unidirektionale Faserverstärkung insbesondere von Langfasern der Polymermatrix bewirkt einerseits im Gegensatz zu einer isotropen Kurzfaserverstärkung eine deutliche Festigkeitssteigerung entlang der Faserrichtung. Aus diesem Grund sind die Fasern in der Regel entlang von berechneten Hauptbelastungslinien ausgerichtet. Derartige Hauptbelastungslinien sind bauteilabhängig und werden insbesondere der zu erwarteten Crash-Belastung angepasst. Gleichzeitig weisen die Glasfasern eine Schlichte auf, die dazu führt, dass eine Haftung zwischen der Faseroberfläche und der Polymermatrix verbessert wird. Eine derartige Schlichte erhöht somit die Festigkeit und verbessert eine Schadenstoleranz. Eine unidirektionale Faserverstärkung bewirkt weiterhin entlang der Kraftflussrichtung eine bessere Kriechbeständigkeit des Bauteils.The unidirectional fiber reinforcement in particular of long fibers of the polymer matrix on the one hand causes in contrast to an isotropic short fiber reinforcement, a significant increase in strength along the fiber direction. Because of this, the fibers are usually aligned along calculated principal load lines. Such main load lines are component dependent and, in particular, the anticipated crash burden is adjusted. At the same time, the glass fibers have a size, which in addition leads, that improves adhesion between the fiber surface and the polymer matrix becomes. Such a size thus increases the strength and improves damage tolerance. A unidirectional fiber reinforcement continues to effect better creep resistance along the direction of force flow of the component.
Zur Wahrung der Transparenz sind die Glasfasern und die Polymermatrix in der Art ausgestaltet, dass der Unterschied ihrer Brechungsindizes (Δn) weniger als 0,05 beträgt. Hierbei ist es zweckmäßig, dass die Schlichte, die sich auf der Glasfaser befindet, ebenfalls in diesem Bereich des Brechungsindex angeordnet ist.to Maintaining transparency are the glass fibers and the polymer matrix designed in such a way that the difference of their refractive indices (Δn) less than 0.05. It is expedient that the sizing, which is on the glass fiber, also in this range of refractive index is arranged.
Eine derartige Einstellung der Brechungsindizes zwischen der Glasfaser und der Polymermatrix kann beispielsweise über die Vernetzungsdichte erfolgen, wenn eine duroplastische Matrix angewendet wird. Andererseits kann bei der Anwendung einer thermoplastischen Matrix deren Berechungsindex über das Molekulargewicht angepasst werden. Ferner kann bei teilkristallinen thermoplastischen Matrizes der Brechungsindex über den Kristallisationsgrad der Matrix eingestellt werden.Such adjustment of refractive indices between the glass fiber and the polymer matrix For example, it can be done via the crosslink density when a thermoset matrix is used. On the other hand, when using a thermoplastic matrix, its calculation index can be adjusted via the molecular weight. Furthermore, in semicrystalline thermoplastic matrices, the refractive index can be adjusted via the degree of crystallization of the matrix.
Des Weiteren besteht die Möglichkeit, auf den Brechungsindex der Glasfasern durch eine gezielte Wärmebehandlung der Glasfaser Einfluss zu nehmen, um diesen an einen Brechungsindex der Polymermatrix anzupassen.Of There is also the possibility on the refractive index of the glass fibers through a targeted heat treatment influence the glass fiber in order to give it a refractive index to adapt to the polymer matrix.
Es hat sich zudem herausgestellt, dass die Transparenz deutlich verbessert wird, wenn der Anteil an Lufteinschlüssen weniger als 1 % beträgt. Hierbei ist es ebenfalls zweckmäßig, dass die Porengröße von etwaigen Lufteinschlüssen kleiner als die halbe Wellenlänge des durchscheinenden Lichtes beträgt, was in der Praxis schwer zu realisieren ist. Es hat sich herausgestellt, dass insbesondere durch ein Vakuumpressverfahren oder durch ein Pultrusionsverfahren bei der Herstellung des erfindungsgemäßen Karosserieelementes die Lufteinschlüsse minimiert werden können und unter den kritischen Wert von 1 % gebracht werden können.It has also been found to significantly improve transparency when the proportion of trapped air is less than 1%. in this connection it is also appropriate that the pore size of any air pockets less than half the wavelength of translucent light is what is difficult in practice to realize. It turned out that in particular by a vacuum press method or by a pultrusion method in the manufacture of the body element according to the invention the air pockets can be minimized and can be brought below the critical value of 1%.
In einer Ausgestaltungsform der Erfindung ist das Karosserieelement schalenförmig ausgestaltet. Die schalenförmige Ausgestaltung ermöglicht es, auf die Darstellung einer komplexen Hohlraumstruktur zu verzichten. Hierbei kann es ebenfalls zweckmäßig sein, dass das Karosserieelement insbesondere in der Schalenbauweise durch Streben oder Rippen verstärkt ist. Hierbei kann es wiederum zweckmäßig sein mehrere schalenförmige Karosserieelemente zusammen zu fügen und beim Fügen ei nen transparenten Klebstoff (z.B. Acrylat- Klebstoffe, Silikonklebstoff) anzuwenden.In An embodiment of the invention is the body element cupped designed. The cup-shaped Design allows to forego the presentation of a complex cavity structure. It may also be appropriate that the body element in particular in the shell construction by Reinforced struts or ribs is. In this case, it may be useful again several shell-shaped body elements to join together and when joining a transparent adhesive (e.g., acrylate adhesives, silicone adhesive) apply.
