Definitions
- the invention relates to a method for producing sailing or surfing boards according to the preamble of claim 1 and to a sailing or surfing board according to the preamble of claim 18.
- a prefabricated EPS foam core is wrapped with a glass fiber mat, placed in the mold and coated or coated with epoxy foam.
- the mold is then closed so that the epoxy foam hardens and forms an impact-resistant laminate together with the glass fiber mat.
- the board body After the board body has been removed from the mold, it is provided with a fine or gel layer, but this can also be introduced into the mold before the wrapped EPS foam core is inserted.
- This so-called epoxy technique allows boards to achieve high rigidity, light weight and good looks.
- the invention has for its object to improve a method according to the preamble of claim 1 so that board bodies can be produced with lower costs and less risk to health, which are at least equal in terms of weight and rigidity to the board bodies produced by epoxy technology. Furthermore, it is an object of the invention to improve a sailing or surfboard according to the preamble of claim 18 in such a way that it is characterized by low weight, high rigidity and low manufacturing costs.
- polyurethane resin which has hitherto been used exclusively as a polyurethane foam for cores of sailing boards, in combination with fiber material and a suitable surface layer results in a laminate which is very impact-resistant and gives the board high rigidity with low weight.
- Polyurethane resin is much cheaper and hardens much faster than epoxy resin, so that through the lower material price and the shorter cycle times result in cheaper overall production. In addition, its processing is associated with lower health risks.
- the polyurethane resin is advantageously adjusted by means of a reaction retarder in such a way that the chemical reaction of its components is delayed by several minutes, in particular by approximately 10 minutes. There is then sufficient time to pour the resin onto the foam core covered with fiber material and then insert the core into the mold and close the mold. If the mold is then kept at a temperature of approximately 80 ° C. during the curing of the shell laminate according to a development of the invention, a curing time of approximately 5 minutes results. If one compares the value with the curing time of approx. 30 minutes required for epoxy resin, it becomes clear that the manufacturing capacity per tool set is considerably higher when using the method according to the invention. One can assume, for example, that 5 times the production capacity can be achieved.
- the polyurethane resin is given a low foaming capacity, so that despite the unavoidable manufacturing tolerances for the manufactured foam core, sufficient pressure is built up in the entire shell laminate area and also occasional deviations of the foam core surface from the size of the shell are compensated for by corresponding thickness fluctuations in the shell laminate.
- a gelccat can be used as the surface layer, with which the mold is lined before the foam core wetted with soaked fiber material is inserted as is already known per se from epoxy technology.
- a film made of thermoplastic material is used as the surface layer, with which the mold is lined before the foam core covered with impregnated fiber material is inserted.
- a thermoplastic film as the surface layer, the impact resistance of the shell increases in particular.
- the introduction of a thermoplastic film into the mold is easier in terms of production technology than the lining of the mold with gel coat, since it is not necessary to treat and polish the mold wall with release agent before introducing the surface layer.
- the film is preferably introduced into the mold using the deep-drawing process. It ensures a visually appealing surface of the board body, prevents any water absorption of the laminate and at the same time protects the laminate from UV radiation. Before the deep-drawing process, the film can be printed with the desired design, so that there is no need to subsequently glue the board surface with design strips or the like. The film also does not have to be pretreated for later application of the top coat.
- Fig. 1 is a schematic representation of a mold
- Fig. 2 is a partial sectional view of a board body produced according to the inventive method and constructed according to the invention.
- the molding tool 1 shown in Fig. 1 consists of two mold halves 2, which are housed in a press 3.
- two film webs 4 are drawn off from two film rolls, not shown, arranged one above the other, and the mold halves 2 are moved at a certain distance by means of clamping frames 5, where they assume the position shown in FIG. 1.
- thermoplastic material which is to form the surface layer 6 of the board body shown in FIG. 2.
- Suitable thermoplastic materials such as ABS (acrylonitrile-butadiene-styrene copolymer), ASA (acrylic rubber-styrene-acrylonitrile copolymer), PC (polycarbonate) and PMMA (polymethyl methacrylate) are suitable as film material.
- the film thickness is between 0.1 and 0.5 mm. The delay is 0.2 mm.
- the outer surfaces of the film webs can already be printed with the desired design.
- a radiant heater 7 is moved between the film webs 4, which heats the film material to the forming temperature.
- the two film webs 4 are moved up or down to the associated mold halves 2 by means of the tensioning frame 5 and deep-drawn by means of an under pressure application.
- the radiant heater 7 is removed from the space between the mold halves 2.
- a foam core 8 is first prefabricated from EPS (polystyrene) or PU (polyurethane) and wrapped with fiber mats or fiber fabric 9.
- EPS polystyrene
- PU polyurethane
- liquid synthetic resin 10 is poured onto the fiber mats on both core sides with the aid of a rake.
- the foam core 8 treated in this way is inserted into the lower mold half 2, in which the deep-drawn film web 4 is still held under reduced pressure, and the press is closed. Due to the pressure of the press and a low foaming capacity of the synthetic resin, it is completely distributed in the space between the foam core 8 and the film 4 and hardens to a closed fiber-reinforced shell, which forms an intimate connection with the film 4 and the foam core 8.
- the curing process takes place at a mold temperature of about 80 ° C in about 5 minutes. Heating elements 11 are provided for heating the mold and are indicated in FIG. 1. If the mold is not heated, but rather hardened at room temperature, the hardening time is about 9 minutes.
- the synthetic resin used to impregnate the fiber material 9 is a specially set polyurethane resin, which is known to have an A component made from polyol and a B component made from isocyanate. A reaction delay is added to the A component, which allows the chemical reaction of the components to take place only after approx. 10 minutes. In addition, the polyurethane resin is given a low foaming power.
- the board body can also be created in the mold 1 without first deep-drawing a film.
- the mold can be lined with a fine layer or a gel coat. For this it is necessary to first carefully clean the inside of the mold, apply a release agent to the walls and polish it. Then gelcoat is sprayed on, rolled up or spread on. This layer hardens in 5 to 15 minutes, whereupon the foam core covered with impregnated fiber material is inserted into the mold and pressed.
- a third possibility is to produce the board body in the manner described but without a surface layer and to apply it later.
- PU lacquer or DD lacquer, gelcoat or polyester-based lacquer can be used for this.
- a method for producing a sail or Wave riding boards are described in which a prefabricated foam core is wrapped with fiber material and a polyurethane resin specially adjusted with a peaction retarder is poured onto the fiber material, whereupon the foam core treated in this way is placed in a mold and the mold is closed to harden the polyurethane resin. Before inserting the treated foam core, the mold is advantageously lined with a surface layer, in particular a thermoformed thermoformed film. In this way, boards with low weight and high rigidity can be manufactured at relatively low manufacturing and material costs.
