Definitions

  • the invention relates to the production of panels, in particular sandwich panels, from fibre-reinforced plastic materials.
  • consideration may in particular be given to panels which are subject to high loads, for example for bridge decks, which have to be able to withstand the total load which is the sum of the weight of the bridge itself and the weight of the road traffic, as well as the local loads which are caused by wheels and the like.
  • a shell is first produced in a mould which has the desired complementary shape of, for example, the bridge deck.
  • This shell consists of fibre-reinforced plastic, as can be produced by impregnating fibre webs or mats with resin.
  • a core is arranged on this shell, following which a second shell is then constructed. After these components have been assembled correctly, the semifinished product obtained is ready for further processing.
  • the process in question comprises four steps, i.e. producing the first shell, producing the core, placing the core on the first shell, producing the second shell and placing the second shell on the core. This is the reason why such a process is time consuming.
  • a further drawback of this method is the risk that the interface between the core and the skins is not completely moistened during adhesive bonding, which may result in inclusions of air which are disadvantageous for the strength and stiffness of the resultant product.
  • impregnating the various parts of the panel is concentrated in one and the same production stage.
  • the two shells and the core are simultaneously formed and attached to one another.
  • the injection material is supplied directly at the underside of the panel, there is hardly any risk of inclusions of air forming.
  • the front of the injection material gradually moves upwards and during this process forces any inclusions of air and possible other gases upwards and pushes them ahead of it, as a result of which these can be extracted in a reliable manner.
  • the material can also be supplied to the upper side so that it gradually moves down. In this case, there may be some inclusions of air, but this does not have to be a problem with all applications.
  • prismatic cores in particular block-like cores
  • the material webs may extend across in each case the upper side of a number of cores, between in each case two adjacent cores and across or along the underside of a number of cores.
  • the method according to the invention may comprise the steps of: - arranging prismatic cores parallel to one another,
  • the method according to the invention preferably also comprises the following steps:
  • the method also comprises the following steps:
  • the transversely placed discharge line or discharge lines ensure that, viewed in the width direction of the cores, a regular and even discharge of the displaced air and/or gases is ensured.
  • the offset position of the discharge lines with respect to the inlet lines which are situated below or above ensures that the path along which the air or the gases are discharged is more or less the same for all cores, viewed from the inlet lines. This prevents the occurrence of short-circuit flows which could result in the formation of an irregular front.
  • the injection material initially flows through the groove in the first surface, that is to say usually in the length direction of each core. As soon as such a groove is completely filled, the injection material can only flow further by leaving the groove. At this stage, the injection material touches the material of the material webs, which results in a throttling effect, thus ensuring that said material of the material webs is moistened along the entire length of the groove. The injection material then passes into the side wall grooves via the material webs, as a result of which the actual formation of the front in the upward and/or downward direction is stimulated.
  • the cores may also play an important part in extracting the gases or the air. This may be achieved by the following steps:
  • each of which has groove parts which are in the second surface thereof, are separated from one another and end at opposite transverse sides of the cores, and which groove parts are parallel to the side walls in which the side wall grooves are situated, which groove parts and which side wall grooves are all separated from one another,
  • the grooves in the second surface of the core elements do not extend as far as the discharge line, so that the injection material again first has to flow through the material of the material web parts on top of the core elements before reaching the discharge line.
  • the problem may occur that the injection material penetrates less well along the edges of the assembly. This may be prevented by the following steps: - placing at least one auxiliary injection line at at least one of the edges of the assembly,
  • said extraction line is connected to the inlet line by means of a low-permeability restrictor having a low flow resistance for gases and a high resistance for transportation of liquids, - extracting a portion and only a portion of the injection material from the extraction line on the injection line, at a location thereof situated opposite the side where the inlet is situated,
  • Extracting the injection material from the auxiliary extraction line has the advantage that the permeation of gases in the assembly on said side is kept in check.
  • preferential transportation of gas may occur via a short-circuit flow to the centre of the assembly, in which centre the main discharge is situated.
  • the invention also relates to a core element for use with the method as described above.
  • This core element is in the shape of a block having a first surface, a second surface situated opposite the first surface and mutually facing longitudinal side faces and mutually facing transverse side faces, wherein the first surface is provided with a continuous groove which extends parallel to the longitudinal side faces.
  • the longitudinal side faces may furthermore be provided with continuous grooves which extend between the first surface and the second surface and are separated from the groove in the first surface.
  • the second surface may also be provided with two mutually separated groove parts, each of which ends at a transverse side face, which groove parts are separated from the grooves in the longitudinal side faces.
  • the first surface may be provided with opposite recesses, each of which is adjacent to a transverse side face and in which the groove situated in said first surface ends. The injection lines may be accommodated in said recesses.
  • Fig. 1 shows a view in perspective and in cross section of a mould with an assembly according to the invention
  • Fig. 2 shows the cross section along H-II from Fig. 1
  • Fig. 3 shows a perspective view of a portion of the core with lines
  • Fig. 4 shows a portion of a side view of the core with lines
  • Fig. 5 shows a perspective view of a core element
  • Fig. 6 shows a perspective view of a core element, pipe piece and material web
  • Fig. 7 shows the view according to VII from Fig. 6
  • Fig. 8 shows a variant of the mould with the assembly according to the invention
  • Fig. 1 shows a mould 1 on which an assembly 3 consisting of adjacent core elements 4 and material webs 5 is arranged. This assembly 3 is covered by the cover layer 10 which is closed along the longitudinal edges with respect to the mould 1.
  • the mould 1 is also provided with longitudinal elements 2 in order to give the assembly 3 a desired shape for the production of a bridge element.
  • the material web 5 is arranged over each core element 4 substantially according to a Z-shaped configuration with a material web part 6 which covers the upper side of the respective core element 4 and a material web part 7 which covers a vertical side of the core element 4 and a horizontal material web part which extends over the mould and is turned away from the core element 4.
  • the inlet hoses 11 extend through in each case one or more of the core elements 4. To this end, a space may be left between two core elements 4, as is shown in Fig. 2, but it is also possible to interrupt one of the core elements 4 in order to make space for the inlet hoses 11.
  • Each inlet hose 11 is connected to a transverse line 12 in such a manner that, as is illustrated in Fig. 2, injection material can spread transversely below the assembly.
  • the transverse lines 12 are porous, in such a manner that the injection material can gradually flow out of them.
  • the view from Figs. 3 and 4 shows that the transverse lines 12 are situated in corresponding transverse recesses 13 of core elements 4 which adjoin one another in the length direction.
  • each transverse recess 13 a longitudinal recess 15 which is provided centrally in the bottom surface of each core element 14 is connected, as is also illustrated in Fig. 5.
  • the injection material initially flows over the mould 1 and the material web parts 8 situated thereon.
  • said longitudinal recess 15 extends between both opposite transverse recesses 13 of each core element 4.
  • the longitudinal recess is completely filled with injection material, the latter is forced to flow out of this longitudinal recess 15 in the transverse direction.
  • the injection material is then pressed through the various layers composed of material web parts 8, resulting in a throttling effect which ensures an even distribution of the injection material across the longitudinal dimension of the core element 4.
  • the injection material then flows upwards in the paths 9 formed between adjacent core elements 4 via the material web parts 8 and the adjoining vertical material web parts 7.
  • the vertically extending side faces of the core elements have vertical ducts 16, 4 which force the injection material to flow upwards, each path 9 gradually being completely filled with injection material in the process.
  • This upper surface has two duct parts 17, 18 extending in the length direction and separated by a wall 19. The injection material flowing across the upper surface passes into said duct parts 17, 18 and flows to the bridge 19.
  • a discharge line 20 extends at the location of the bridge 19 of the adjacent core elements 4 which are next to one another. Via this extraction line, gases and/or air are extracted.
  • the position of these discharge lines is chosen such mat their path and length which the injection material has to travel from the transverse line 12 to the discharge line 20 is of equal length in all parts of the core. This assists in filling the core completely and without inclusions of air.
  • This inlet line 12 is composed of inlet pieces 21, the length of which is equal to the thickness of a core element 4. As soon as a core element 4 with a material web 5 thereon has been placed, an opening 22 is made in the vertical part 7 of the material web 5, so that an inlet line piece 21 can be inserted into said opening 22 and can be attached to a preceding inlet piece 21. Thus, by placing the core elements 4 and the material webs 5, the transverse line 12 is gradually constructed.
  • Fig. 8 shows that in addition to the inlet line 11 and transverse line 12, an additional inlet line 23 and discharge line 24 may be provided in the edge region of the assembly. Thus, it is ensured that the material webs can also be readily impregnated in those edge regions.
