Verfahren zur Herstellung von SchichtstoffenProcess for the production of laminates
Die Erfindung betrifft ein VerfaKren zur Herstellung von Schichtstoffen aus einer kunstharzgetränkten Basisschicht und einer oder zwei saugfähigen Deckschichten.The invention relates to a VerfaKren for the production of Laminates made of a synthetic resin-soaked base layer and one or two absorbent cover layers.
Bei der Herstellung von Skibauteilen, welche dem Ski sowohl als Obergurt und/oder Untergurt als auch als abriebfeste, dekorative Deckfläche dienen, werden verschiedene Verfahren verwendet. Einerseits erhält man solche Bauteile durch Verkleben von faserverstärkten Laminaten mit verschiedenen Thermoplastfolien oder dekorativen Schichtdofftafeln, andererseits kann die faserverstärkte Laminatschicht in vorimprägniertem Zustand (B-Zustand, Prepreg) mit ebenfalls vorimprägnierten nicht verstärkten Trägerschichten auf Basis harzimprägnierter Papiere oder Vliese verpreßt werden und man erhält dadurch einen Verbundwerkstoff hoher mechanischer Festigkeit mit harzreicher, gegebenenfalls dekorativer und abriebfester Oberfläche. Ähnliche Produkte erhält man durch die Verarbeitung der angeführten Schichtstoffe und Harze im Naßpreßverfahren.In the production of ski components, which the ski can use as an upper belt and / or lower belt as well as abrasion-resistant, Various methods are used to serve a decorative cover surface. On the one hand, you get such components by gluing fiber-reinforced laminates with various thermoplastic films or decorative laminated panels, on the other hand, the fiber-reinforced laminate layer in the pre-impregnated state (B-state, prepreg) with also pre-impregnated, non-reinforced carrier layers based on resin-impregnated papers or fleeces are pressed and a composite material of high mechanical strength with resin-rich, optionally decorative and abrasion-resistant surface. Similar products are obtained by processing the listed laminates and resins in the wet molding process.
Alle diese Verfahren sind arbeitsintensiv, verlangen zwei oder mehrere Imprägniervorgänge und aus Rationalitätsgründen größere Produktionsserien. All of these processes are labor-intensive, require two or more impregnation processes and, for reasons of rationality, larger production series.
Durch die vorliegende Erfindung können in einem rationellen Verfahren dekorative, faserverstärkte Bauteile hergestellt werden, welche sich insbesondere als Skioberfläche eignen.The present invention enables decorative, fiber-reinforced components to be produced in a rational process which are particularly suitable as a ski surface.

Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung von Schichtstoffen, bestehend aus einer faserverstärkten Grundschicht, einem duromeren Kunstharz und mindestens einer Deckschicht auf Basis von saugfähigem Material, wobei die Schichten unter Druck und Aushärtung des duromeren Kunstharzes mit einander verbunden werden, dadurch gekennzeichnet, daß auf die in vorgehärteter Form vorliegende Grundschicht, die einen Kunstharzgehalt von 40 - 70 % besitzt, mindestens eine Schichte saugfähigen Materials, unter gleichzeitiger vollständiger Durchtränkung des saugfähigen Materials aus dem Harzangebot der Grundschicht und unter gleichzeitiger Verbindung und Aushärtung aller Schichten, aufgepreßt wird, wobei der Harzanteil der Grundschicht innerhalb der Grenzen von 40 - 70 % so gewählt wird, daß ein Fluß des Kunstharzes erzielt wird, der gemessen bei einem Druck von 5 kg/cm , 150° C und 10 Minuten Dauer mindestens 10 % beträgt.The present invention relates to a process for the production of laminates, consisting of a fiber-reinforced base layer, a thermoset synthetic resin and at least one cover layer based on absorbent material, the layers being connected to one another under pressure and curing of the thermoset synthetic resin, characterized in that At least one layer of absorbent material is pressed onto the pre-cured base layer, which has a synthetic resin content of 40-70 % , with simultaneous complete saturation of the absorbent material from the resin supply of the base layer and with simultaneous connection and curing of all layers, the Resin content of the base layer is chosen within the limits of 40-70% so that a flow of the synthetic resin is achieved which, measured at a pressure of 5 kg / cm, 150 ° C and 10 minutes duration, is at least 10 % .
Gewebe, Vliese oder andere Faserprodukte werden mit soviel Kunstharz imprägniert, nämlich 40 - 70 %, daß für die aufzulegenden Deckschichten beim Verpressen der Kombination genügend Harz vorhanden ist um diese Deckschichten vollständig zu durchtränken und zu überschichten. Normalerweise sind für die Laminatherstellung 30 - 40 % Harz ausreichend. Die Aufwandmenge an Harz hängt vom "Fluß" des jeweiligen Harzes ab. Dieser "Fluß" muß bei Verpressungs-Fabrics, fleeces or other fiber products are impregnated with enough synthetic resin, namely 40-70 %, that there is enough resin for the cover layers to be applied when the combination is pressed to completely soak and cover these cover layers. Usually 30-40% resin is sufficient for laminate production. The amount of resin applied depends on the "flow" of the respective resin. This "flow" must be used for grouting

daß unter den Bedingungen der Verpressung genügend flüssiges Harz zur Verfügung steht, um die Deckschichten völlig zu durchdringen und somit eine einwandfreie Harzschicht an der Oberfläche zu gewährleisten. Natürlich muß dabei dem Rechnung getragen werden, wie stark die zu tränkende Deckschichte sein soll. In der Regel wird eine dünnere Deckschicht eine geringere Harzkonzentration in der Basisschicht benötigen als sie eingesetzt werden muß, wenn die Deckschichte stärker ist. Natürlich spielt hier auch die Fließfähigkeit des Harzes der Basisschicht eine Rolle, sodaß eben auch bei genügendem Harzangebot in der Basisschicht zu beachten ist, daß der Fluß exen Wert erreicht, der eine einwandfreie Durchtränkung der Deckschichte gewährleistet. Auch hier wird der Fluß mit zunehmender Stärke der Deckschichte höher zu wählen sein, sodaß z.B. ein Fluß der Mindestgrenze von 10 % bei einer Auflage von 70 - 80 g/cm völlig ausreicht, während bei stärkerer Auflage z.B. über 100 oder gar 150 g/cm zweckmäßig mit einem höheren Fluß zu arbeiten ist.that under the conditions of the pressing there is enough liquid resin available to completely penetrate the cover layers and thus to ensure a perfect resin layer on the surface. Of course, it must be taken into account how thick the top layer to be impregnated should be. As a rule, a thinner top layer will require a lower resin concentration in the base layer than must be used if the top layer is stronger. Of course, the flowability of the resin of the base layer also plays a role here, so that, even if there is sufficient resin in the base layer, it must be ensured that the flow reaches exen value which ensures perfect impregnation of the top layer. Here too, the higher the thickness of the outer layer, the higher the flow rate, so that, for example, a flow of the minimum limit of 10 % is completely sufficient for an application of 70-80 g / cm, while for a higher application, for example, over 100 or even 150 g / cm is expedient to work with a higher flux.
Durch die Verwendung von dekorativen Bahnen aus Papier, Vliesen oder ähnlichen Stoffen bzw. von eingefärbten Harzen und nicht eingefärbten Bahnen für die Deckschicht können beliebige Oberflächeneffekte erzielt werden. Die Verwendung von saugfähigen Materialien, gut fließfähigen Harzen und/oder geeigneten Preßbedingungen ist Voraussetzung für ein einwandfreies Gelingen des Verfahrens.By using decorative strips made of paper, fleece or similar materials or colored resins and non-colored strips for the top layer, any desired surface effects can be achieved. The usage of absorbent materials, good flowable resins and / or suitable pressing conditions is a prerequisite for a perfect success of the procedure.
Die Grundschicht besteht vorwiegend aus Glasfasern, diese können aber auch ganz oder teilweise durch Kohlenstofffasern ersetzt werden, wobei die Konstruktion der Grundschicht ein Gewebe, Gewirke, Vlies oder ähnliches sein kann. Als Deckschicht sind vor allem Papier, saugfähi-The base layer consists mainly of glass fibers, these but can also be completely or partially replaced by carbon fibers, the construction of the base layer a woven, knitted fabric, fleece or the like can be.
