Abstract
Description
Verfahren zur Herstellunz eines Preszkörpers und nach dem Verfahren hergestellter Presskörper Die vorliegende L'rfindung bezieht sich auf ein Verfahren zur Herstellung eines Presskörpers, vorzugsweise eines Ski in einer Pressform, wobei der Presskörper mindestens in seinem Kern aus einer zellig strukturierten, aber festen Masse bestehen soll. Ski dieser Art werden üblicherweise so hergestellt, daß in einer Formpresse eingebrachte IIalbfabrikate unter Anwendung von Aussendruck thermisch ausgehärtet und verklebt werden. Es ist auch schon vorgeschlagen worden, in die zu einem Ski zu verbindenden Teile als Kern eine aufblasbare Plastik- oder Oummieinlage einzulegen und den zur Formgebung notwendigen Druck mit zugeführter Druckluft von iimen her zu erzeugen. Diese Lösung hat aber den Nachteil, daß der entstehende Hohlkern in einem weiteren Arbeitsgang mit einem Fülimaterial ausgeschäumt werden muss, was wegen der Dimensionen des Hohlraums schwierig ist. Process for the production of a pressed body and according to the process produced compact The present invention relates to a method for the production of a press body, preferably a ski in a press mold, wherein the pressed body, at least in its core, consists of a cellular structure, but solid mass should exist. Skis of this type are usually made in such a way that that semi-finished products brought into a molding press using external pressure thermally cured and glued. It has also been suggested in the parts to be connected to a ski as a core an inflatable plastic or Insert the Oummieeinlage and apply the pressure necessary for shaping To generate compressed air from iimen. This solution has the disadvantage that the The resulting hollow core is foamed with a filling material in a further operation must be, which is difficult because of the dimensions of the cavity.
Der Erfindung liegt zur Vermeidung dieses Nachteils die Aufgabe zugrunde, ein Verfahren zu schaffen, nach dem insbesondere Ski in einem Arbeitsgang auch unter Erzeugung eines Innendruckes pressgeformt werden können.In order to avoid this disadvantage, the invention is based on the object to create a method according to which, in particular, skis can also be used in one operation Generating an internal pressure can be compression molded.
Das vorliegende Verfahren is-t erfindungsgemäss dadurch gckennzeichnet, daß als Kernmaterial ein plastisch deformierbarer Kunststoff verwendet wird, der die Sigenschaft hat, sich beim thermischen Aushärt en unter beträchtlicher Druckentwicklung aufzublähen und so den zur Formgebung notwendigen Druck von innen her zu erzeugen. Im ausgehärteten Zustand bildc 1; ,.er Kunststoffkern ein zellig strukturiertes, leichtes, aber meche,-nisch festes Material, mit guten schwingungsdämpfenden Eigenschaften. Es ist ohne weiteres möglich, den Kunststoffkern mehrteilig, in Bändern oder Streifen auszulegen und mit verstärkenden Einlagen zu armieren. Das Verfahren ermöglicht es, einen Verbundski in einem einzigen Arbeitsgang herzustellen.According to the invention, the present method is characterized in that that a plastically deformable plastic is used as the core material, the has the property of being thermally cured under considerable pressure development to inflate and thus to generate the pressure necessary for shaping from the inside. In the hardened state fig. 1; , .er plastic core a cellular structured, light but mechanically strong material with good vibration dampening properties. It is easily possible to make the plastic core in several parts, in bands or strips to be laid out and reinforced with reinforcing inserts. The procedure enables it is to produce a composite ski in a single operation.
Solche Ski zeichnen sich durch geringes Gewicht und günstige Torsions- und Biegeeigenschaften aus.Such skis are characterized by their low weight and favorable torsional and bending properties.
Der nach dem erfindungsgemässen Verfahren hergestellte Presskörper, insbesondere Ski, ist dadurch gekennzeichnet, dass zumindest sein Kern aus einer zellig strukturierten IIesse besteht.The pressed body produced by the method according to the invention, in particular skis, is characterized in that at least its core consists of a cell-structured IIesse consists.
Obschon das Verfahren sich im wesentlichen auf die Herstellung eines pressgeformten Slri bezieht, ist es ohne weiteres möglich, das Verfahren der inneren Druckerzeugung mit sich aufbl-ahendem Kunststoff auf die Herstellung irgendwelcher fonagepresster Körper bzw. Verbundkörper anzuwenden.Although the process essentially focuses on the manufacture of a In relation to press-molded Slri, it is readily possible to use the process of internal Pressure generation with inflating plastic on the production of any use pressed body or composite body.
In der Zeichnung ist ein Beispiel für die Ausführung des erfindungsgemässen Herstellungsverfahrens dargestellt.In the drawing is an example of the implementation of the inventive Manufacturing process shown.
Es zeigt: Fig. 1 einen Querschnitt durch die Pressform mit den eingelegten Teilen des Verbundski vor dem thermischen Aushärten der Kernmatte; Pig. 2 einen Querschnitt durch die Pressform mit dem epandierten und ausgehärteten Kernmaterial.It shows: 1 shows a cross section through the compression mold with the inserted parts of the composite ski before the thermal curing of the core mat; Pig. 2 shows a cross section through the compression mold with the epanded and hardened one Core material.
Gemäss Fig. 1 wird in die Hohlform 1, zu der ein Deckel 2 gehört, eine Grundplatte 35 eingelegt, die noch mit einem speziellen Gleitbelag und Kanten 36 versehen sein kann. Auf diese Grundplatte 55 wird ein in seiner Rohform plastisch deformierbarer Kunststoffkern 31 eingelegt, der die Eigenschaft hat, sich beim thermischen Aushärten unter beträchtlicher Druckerzcugung aufzublähen. Solche Kunststoffe sind als Splioe-Schaum (Ciba (ARL) LTD GB) im Handel erhältlich. Der Kunststoffkern 31 ist dabei vorher mit Glasfaser-Schichten 32, die mit thermisch aushärtbarem Kunstharzkleber geträidct sind, bewickelt. Dann wird eine Deckplatte 33, die ebenfalls mit Schutzkanten 34 versehen sein kann, über den eingelegten Kunststoffkern eingelegt. Auch die Seitenwände der Hohlform könnten mit Seitenplatten ausgekleidet werden.According to Fig. 1, in the hollow mold 1, to which a lid 2 belongs, a base plate 35 is inserted, which is still with a special sliding coating and edges 36 can be provided. On this base plate 55 is a plastic in its raw form deformable plastic core 31 inserted, which has the property of thermal Cure to inflate under considerable pressure. Such plastics are commercially available as Splioe foam (Ciba (ARL) LTD GB). The plastic core 31 is done beforehand with fiberglass layers 32, which are covered with thermosetting synthetic resin adhesive are worn, wrapped. Then a cover plate 33, which is also with protective edges 34 can be provided, inserted over the inserted plastic core. The side walls too the mold could be lined with side plates.
Beim thermischen Aushärten in der geschlossenen Porm bläht sich der lcunststoffkern 31 unter beachtlicher Druckerzeugung auf und noch bestehende Hohlräume 3 werden, wie Pig. 2 zeigt, ausgefüllt. Das Glasfasergewebe 32 wird also von innen her -an die Preßform 1, 2 angepresst und bildet mit der Deck-und Bodenplatte einen Verbundkörper, dessen Kern ein leichtes, zellig strukturiertes Material ist.When thermally hardening in the closed porm, it expands Plastic core 31 with considerable pressure generation on and still existing cavities 3 will be like Pig. 2 shows, filled out. The fiberglass fabric 32 is so from the inside pressed against the mold 1, 2 and forms one with the top and bottom plate Composite body, the core of which is a light, cellular structured material.
