Definitions

  • the present invention relates to the cutting of hybrid panels for the coating of automobile interiors by means of the application of laser radiation.
  • This invention provides a method for cutting panels consisting of a polymer matrix reinforced by natural fibers and lined with decorative fabrics, panels that have, predominantly, a use as automobile interior lining.
  • the hybrid panels referred to in the present invention consist of the use of natural fibers such as linen, sisal, hemp or jute to reinforce a polymer matrix (mainly polypropylene or polyurethane).
  • This type of hybrid panels that incorporate natural fibers have a series of advantages over those that use fiberglass or petroleum-derived fibers.
  • the use of non-perishable resources such as natural fibers is obvious ecological benefits.
  • these hybrid panels can be recycled once the life of the vehicle is over and, ultimately, they can be used as fuel with a much lower ash production than in the case of fiberglass reinforced panels.
  • hybrid panels reinforced with natural fibers offer a response to mechanical stresses similar to that offered by fiberglass reinforced panels but with a 30 to 40% reduction in panel weight. Therefore, the use of this new type of hybrid panels as a lining of car interiors means a reduction in its weight, which directly affects a reduction in fuel consumption and, ultimately, a saving for the car user. In addition, they provide greater insulation from the outside due to their high noise absorption capacity. They also allow both decorative elements and fasteners to be coupled in a simple way (by compression) which considerably reduces manufacturing time and costs.
  • the main tasks that must be performed in order to obtain the directly usable panels as a coating for the interior of automobiles are the following: cutting of the fibers, drying them, mixing with the matrix polymer, rolling the mixture, application of the fabrics exterior and interior of the panel (usually polyester), pressed with heat input (simple or blown), demoulding, cutting and die cutting of the panel to its final dimensions.
  • One of the advantages of the present patent is the possibility of making cuts practically impossible to make by mechanical methods. Thus it is possible to cut profiles in three dimensions with any shape or figure with a uniform finish.
  • this patent has the advantage of being able to drill a wide variety of diameters, from a few tens of micrometers, which is practically impossible by mechanical methods.
  • Another of the advantages presented by the invention object of the present patent is the fact that the processing is carried out without contact with the part, so that, in no case is it subjected to mechanical solicitations during the laser treatment process, which It is inherent in mechanical processes. In addition, as no contact is established between the part and the tool, it does not suffer wear or corrosion, so it is not necessary to sharpen or replace it.
  • the method of cutting hybrid panels for interior lining of automobiles object of the present patent is to subject the panel to the action of laser radiation. Cutting with the laser beam will preferably be done cold once the panel has been removed from its mold in order to give it the final shape and dimensions. The best results are obtained when the panel has been completely lined, both on its inner face as on the outside.
  • the hybrid panel to be cut is placed on a support appropriate to its dimensions in a mobile system. This system will be connected to an automatic panel position control system.
  • the laser beam is driven by means of one or more mirrors towards the piece to be cut. Although the beam can affect the piece at a certain angle, the best results have been obtained for a normal incidence to it.
  • the laser radiation can come from a laser device of any wavelength such as, for example, a CO2, CO, N2, Nd: YAG, Er.YAG, laser
  • Nd glass, Ruby, HeNe, HeCd, HeHg, Cu, del, Ar, de
  • the necessary power for this type of lasers can be between 50 and 3000 W, having obtained the best results when working with a power of between 300 and 1000 W.
  • the laser beam is focused on the surface of the hybrid panel by means of a lens This lens will preferably have a focal length of between 100 and
  • the cut In order to obtain an optimum quality of the wall of the cut it is preferable to perform the cut at speeds of between 50 and 200 mm / s. In this way the energy density reached on the hybrid panel is such that it allows to vaporize directly the volume of panel irradiated by the laser beam, melting a small lateral layer thereof, which, when cooled, seals the wall of the cut. This results in a cut with excellent quality that prevents the growth of g
  • fungi inside the panel Although the process does not require any gas, a small flow of a protective gas from the lens can be used. Said gas can be oxidizing (O2, C ⁇ 2 ?, Compressed air) or inert (N2, Ar, He, Ne). The best results have been obtained using nitrogen at a pressure between 0.1 and 1 xlO Pa.
  • a practical example of cutting hybrid panels for car interiors is the following: Polypropylene panels (5 mm thick) reinforced by linen fibers, with polyester inner and outer linings are cut by means of a laser

Abstract

L'invention porte sur des panneaux hybrides servant à revêtir l'intérieur d'automobiles et susceptibles d'être découpés à l'aide d'un procédé s'inspirant d'un rayonnement d'un faisceau laser. Ce procédé, de part sa grande flexibilité, permet de découper différents types de panneaux sans avoir à changer d'équipement ou d'outil, il suffit seulement de modifier les paramètres de traitement. Ce procédé contribue à améliorer considérablement la qualité de la découpe par rapport aux procédés mécaniques conventionnels ou à la découpe par jet d'eau.
