Description

Verfahren zur Herstellung von Dekorations-, Konstruktions-oder Verstärkungselementen aus thermoplastischen Kunststoffen Dekorations-, Konstruktions-oder Verstärkungselemente mit einer den Honigwaben Ehnlichen Struktur, die nachfolgend kurz als"Verstärkungselemente"bezeichnet werden, können aus Metallfolie oder Papier nach dem Reck-oder Wellverfahren hergestellt werden. Nach dem Reckverfahren werden glatte Bänder des Ausgangsmaterials aufeinander gelegt und wechselseitig so zu einem Paket verklebt, daB beim Auseinanderziehen oder Recken des Pakets senkrecht zu dem Verlauf der verklebten Bnder"Verstärkungselemente"mit einer den Honigwaben ähnlichen Struktur entstehen. Process for the production of decorative, structural or reinforcing elements made of thermoplastic materials for decoration, construction or reinforcement with a honeycomb-like structure, hereinafter referred to as "reinforcement elements" for short can be made of metal foil or paper by the stretching or corrugating process will. After the stretching process, smooth strips of the starting material are placed on top of one another and glued alternately to form a package so that when they are pulled apart or stretching the package perpendicular to the course of the bonded tapes with "reinforcing elements" a structure similar to the honeycomb arise.

FUr das Wellverfahren wird das bandförmige Ausgangsmaterial zunächst trapezförmig gewellt und die einzelnen Bander dann so miteinander verklebt, daB ebenfalls"Verstärkungselemente"mit Wabenstruktur entstehen. Nach diesem Wellverfahren können auch faserverstärkte, duroplastische Kunststoffe zu"Verstärkungselementen" mit Honigwabenstruktur verarbeitet werden.For the corrugation process, the strip-shaped starting material is first used trapezoidal corrugated and the individual bands then glued together so that "Reinforcement elements" with a honeycomb structure are also created. After this corrugation process fiber-reinforced, thermosetting plastics can also be used as "reinforcement elements" can be processed with a honeycomb structure.

Die aus den vorgenannten Ausgangsmaterialien hergestellten"Verstärkungselemente"müssen geklebt werden. Jedoch ist die Anwendung von Klebstoffen, insbesondere bei der Verarbeitung von duroplastischen Kunststoffen, nicht immer unbedenklich, da die einzelnen Verklebungen verschiedene Festigkeit besitzen. AuBerdem können die aus den vorgenannten Materialien hergestellten"Verstärkungselemente"dreidimensional nicht bleibend verformt werden. Diese Eigenschaften sollten aber die"Verstärkungselemente" haben, um sie als Bauelemente für Kuppeln oder Khnlich geformte Bauteile verwenden zu können.The "reinforcement elements" made from the aforementioned starting materials must to be glued. However, the use of adhesives, especially in processing of thermosetting plastics, not always harmless, as the individual bonds have different strengths. In addition, they can be made from the aforementioned materials manufactured "reinforcement elements" are not permanently deformed in three dimensions. These properties, however, are what the "reinforcing elements" should have in order to use them as building elements to be used for domes or similarly shaped components.

Es wurde nun ein Verfahren zur Herstellung von Dekorations-, Kontruktions- oder Verstärkungselementen aus vorgeformten Kunststoffbändern gefunden. Danach werden in Form von Trapezen oder Sinuakurven gewellte Bänder aus thermoplastischen Kunststoffen aufeinander gelegt und an den Berührungsstellen verschweißt.There has now been a process for the production of decorative, construction or reinforcement elements made from preformed plastic strips. After that will be in the form of trapezoids or sinua curves, corrugated strips made of thermoplastics placed on top of each other and welded at the points of contact.

Die als Ausgangsmaterial verwendeten Bander aus thermoplastischen Kunststoffen werden zunächst nach bekannten Verfahren, wie beispielsweise durch PrXgen, Tiefziehen oder entsprechende FUhrung des Extrudierens, unter ErwKrmungen so verformt, daß sie die Form von einandergereihten Trapezen odet-von Sinuskurven annehmen. Jeweils zwei der vorgeformten Bander werdenentsprechend Figur 1-dann so aufeinander gelegt, daß sie sich an den Stellen berühren, die am weitestens von ihrer mittleren Llngsachse entfernt sind. Auf diese Weise entstehen streifenfSrmige Gebilde, die, von der Seite gesehen, sechseckige oder spitzovale Hohlräume aufweisen. An den BerUhrungsstellen werden die aufeinander liegenden Bander nunmehr miteinander verschweiBt.The thermoplastic tapes used as the starting material Plastics are first made by known methods, such as by Embossing, deep drawing or corresponding extrusion control, with heating deformed in such a way that they have the shape of a series of trapezoids or sine curves accept. In each case two of the preformed bands are then as shown in FIG placed on top of each other so that they touch at the points furthest from their central longitudinal axis are removed. In this way, stripes are created Structures which, viewed from the side, have hexagonal or pointed oval cavities. At the points of contact, the bands lying on top of one another are now connected to one another welded.

Anschließend können jeweils zwei solcher Vorformlinge in der fUr ihre Herstellung beschriebenen Weiße aufeinander gelegt und an den BerUhrungsstellen miteinander verschweißt werden. Es ist aber auch möglich, auf einen Vorformlii- nur Jeweils ein weiteres'vorgeformtes Band in der vorstehend beschriebenen Weise aufzulegen und zu verschweißen.Then two such preforms can be placed in the for their Manufacture described whites placed on top of each other and at the points of contact are welded together. But it is also possible to use a preform only one additional preformed band in each case in the manner described above lay up and weld.

"VerstSrkungselemente", die gegen Druckbelastungen besonders unempfindlich sind, entstehen erfindungsgemäß, wenn zwischen die gewellten Bänder-entsprechend Figur 2-jeweils ein glattes Band eingelegt und zusammen mit den gewellten Bändern an den Berührungsstellen verschweißt wird."Reinforcement elements" that are particularly insensitive to pressure loads are, according to the invention, if between the corrugated bands-accordingly Figure 2 - each a smooth band is inserted and together with the corrugated bands is welded at the contact points.

Zur Herstellung der Verstärkungselemente"können auch Bänder aus thermoplastischen Kunststoffen verwendet werden, in die Füll-oder Verstärkungsmaterialien, wie beispielsweise Gewebe oder Vliese aus Textilien oder Glasfasern, Metallfolien usw. eingelagert sind. Derartige Bänder können nach bekannten Verfahren hergestellt werden.For the production of the reinforcement elements "tapes made of thermoplastic Plastics are used in the filler or reinforcement materials, such as Fabrics or fleeces made of textiles or glass fibers, metal foils, etc. are stored are. Such tapes can be produced by known methods.

Das Verschweißen der Bander wird mit geeigneten Vorrichtungen nach bekannten Schweißverfahren durchgeführt. Besonders vorteilhaft sind hierfür HochRrequenzverfahren oder das Wärmeimpuleverfahren. Die Schweißung kann mittels kammförmiger Heizquellen an mehreren BerUhrungsstellen der aufeinander liegenden Bander aus thermoplastischen Kunststoffen gleichzeitig erfolgen.The welding of the bands is done with suitable devices known welding process carried out. High-frequency methods are particularly advantageous for this or the heat pulse method. The welding can be done by means of comb-shaped heating sources at several points of contact of the thermoplastic strips lying on top of one another Plastics take place at the same time.

Die erfindungsgemäß hergestellten "Verstärkungselemente" zeichnen sich durch besondere Featigkeit der Verbundstellen aus und können in der Wlrme dreidimensional, beispielsweise zu kuppelförmigen Gebilden, bleibend verformt werden, wenn die zu ihrer Herstellung verwendeten BEnder keine Einlagen enthalten, die, wie beispielsweise Gewebe oder Metallfolien, eine solche Verformung verbieten. Mit Hilfe derartig dreidimensional verformter"VerstErkungselemente"ist es möglich, den auf die gewölbte Fläche wirkenden Druck radial aufzunehmen. Diese Möglichkeit ist insofern ein Vorteil, als die"Verstärkungselemente"in radialer Richtung die größte Aufnahmefähigkeit für Druckkräfte haben.Draw the "reinforcement elements" produced according to the invention are characterized by the special features of the connection points and can be three-dimensional in the heat, for example to dome-shaped structures, permanently deformed when the to Belts used in their manufacture do not contain any inserts, such as Fabric or metal foils, prohibit such deformation. With the help of such a three-dimensional deformed "reinforcement elements" it is possible to act on the curved surface To absorb pressure radially. This possibility is an advantage in that the "reinforcement elements" in radial direction have the greatest capacity for compressive forces.

Die erfindungsgemäß hergestellten Produkte können als Dekorations-, Konstruktions-und Verstärkungselemente eingesetzt werden. Besonders geeignet sind sie für die Herstellung von lichtdurchlässigen oder durchsichtigen Verbundteilen, die vielseitig, beispielsweise im Iiausbau, verwendet werden können.The products produced according to the invention can be used as decorative, Construction and reinforcement elements are used. Are particularly suitable they for the production of translucent or transparent composite parts, which can be used in a variety of ways, for example in expansion.
