Definitions

  • the present invention relates to a method for production of composite sheets as described in the introductory part of claim 1.
  • the invention is also relates to an apparatus for production of the composite sheets.
  • weave This term not only covers matrices that are woven but also matrices where long, arranged threads are assembled by stitching.
  • the term "weave” is used for composites with long fibres in contrast to "non-woven" materials, which are mixtures of short fibres and are used, for example, in insulation mats.
  • a so-called belt press can be used, which is known, for example, from international patent application W097/26397.
  • a matrix of threads is passed through a heating process and a pressing process, where the pressing process takes place between pressure rollers with belts around them arranged in such a way, that the composite sheet in the form of a continuos web is pro- cuted between the belts on each side of the sheet.
  • belt presses are very ex-
  • This method has a lot of disadvantages.
  • To achieve a complete melting of the weave it is exposed to a strong thermal radiation on a preheating stage.
  • the disadvantage of the preheating stage is that a temperature is reached on the external side of the weave, which is close to the decomposition temperature for the polymer, for example, 230°C for polypropylene, abbreviated PP, while the temperature in the centre of the weave is much lower, for example, 140°C, and often below melting point, which for PP is 165°C. Consequently, a decomposition of external polymer fibres takes place in the weave, which is extremely inappropriate, but accepted in order to obtain necessary heating to the final temperature, where the polymer is melted to form the composite.
  • the purpose of the invention is to provide a method and an apparatus for production of composite sheets from a weave, where the above-described disadvantages are avoided, and where heating of the weave preferably takes place without thermal radiation preheating.
  • the void volume is that volume of the composite which consists of air. The bigger the void volume, the less strength has the composite.
  • the invention is characterised in that the weave comprises polymer threads, preferably PP, PET or PTFE plus threads of a reinforcing material, preferably glass fibres, but carbon fibres or fibres of other materials could be used as well.
  • polymer threads preferably PP, PET or PTFE plus threads of a reinforcing material, preferably glass fibres, but carbon fibres or fibres of other materials could be used as well.
  • the invention is characterised in that the share of glass threads in the weave is between 55% and 75%, preferably between 60% and 70%, and most preferably 60%.
  • the share of reinforcing material like glass
  • a further embodiment of the invention is characterised in that the hot rolling tempera- ture is between 0° and 20° below the decomposition temperature for that of the at least two materials that has the lowest decomposition temperature, preferably between 0° and 10° below the decomposition temperature and most preferably between 0° and 6° below the decomposition temperature.
  • the decomposition temperature for PP is 220°. At heating above that temperature, a decomposition process of the fibres begins. Therefore, it is important that the polymer is not heated up to a temperature higher than the decomposition temperature. On the other hand, it is important that the polymer is as viscous as possible, so that it finally can settle around the reinforcing fibres to a sufficient extent.
  • the invention is characterised in that the process rate is be- tween 0.5 m/min and 2 m/min, preferably between 1.4 and 1.6 m/min. It is appropriate to have a high production rate, as in this case the product can be manufactured in a shortest possible time.
  • a pressing process which includes both hot rollers and cold rollers, it is important, that the composite sheet is transported from the hot process to the cold pressing process before the material is cooled off so much, that a sufficient homogenisation and shaping of the material can not take place during the final pressing process with cold rollers.
  • the production must not be so fast, that a sufficient homogenisation, that is flowing of the polymer and enclosure of the glass fibres, does not occur.
  • the stiffness is expressed with a so-called Young's modulus, which is a ratio between a compressive or tensile stress on the material in the composite sheet's longitudinal direction and the corresponding relative linear expansion. At a certain tensile stress on the composite sheet, the Young's modulus is the bigger, the less the sheet is extended as a result of tension.
  • the invention is characterised in that the heating process in- eludes heating with thermal radiation. This is a possibility, which can be used in connection with the invention. It has however turned out that the stage can be omitted.
  • the invention is characterised in that the heating by thermal radiation provides a temperature of the weave between 1 10° and 170°C, preferably between 120°C and 160°C, and most preferably 140°C. Provided that preheating is used, this temperature has proven to be advantageous. However, it is important that during the thermal radiation treatment, the surface of the weave is not supplied with so much heat that it decomposes. In general, it is not necessary to preheat the weave, but it is not impossible in certain cases that an advantage can be obtained by heating in addition to the hot pressing rollers.
  • the invention is characterised in that during the pressing process the weave is subjected to a rolling pressure only where the thickness of the composite sheet is larger than a certain adjustable minimum thickness.
  • the minimum thickness is adjusted to an appropriate value with regard for the weave's thickness and the number of the weaves melted and pressed together.
  • the invention is characterised in that during the cooling down process, the weave is subjected to a cold rolling pressure of at least one rotating cold roller.
  • a cold rolling pressure of at least one rotating cold roller After the first step of the pressing process, where the composite sheet is formed with the weave as a starting material, one or more subsequent pressing stages can be used with advantage, where the co ⁇ esponding rollers have a much lower temperature than the hot rolling temperature.
  • the not yet hardened composite sheet can be shaped in accordance with predetermined profiles. The sheet can, for example, be given a wavy or serrated shape depending on the required final product.
  • the cold rollers must therefore be appropriately designed for such special purposes.
  • the invention is characterised in that the weave is subjected to surface structuring during the pressing process in hot conditions and/or by pressing during the cooling down process.
  • surface structuring of the weave can, for example, be carried out by cold rollers if they have a surface design which after pressing is trans- ferred to the composite sheet surface.
  • the weave it can be furnished with holes of different shapes to supplement specific structuring of the weave.
  • An apparatus for production of composite sheets comprising one or more mediums for feeding in of at least one matrix of threads, preferably a weave with polymer threads and glass threads, at least one device for heating of the matrix, at least one heated rotating roller, over which the matrix is passed, and where the rotating roller is heated up to a hot rolling temperature which is above melting point for that of the at least two materials in the matrix with the lowest melting point and below melting point for that of the at least two materials with the highest melting point, and where the hot rolling temperature is below the decomposition temperature for any of the at least two materials, at least one arrangement for pressing the matrix together, and at least one device for cooling the matrix down is according to the invention characterised in that the matrix pressing arrangement includes at least one rotating hot roller, which is heated up to the hot rolling temperature.
  • the apparatus is characterised in that said at least one arrangement for pressing said at least one matrix comprises at least one set of two hot rollers with parallel rotation axes and rotating in opposite directions with equal surface speed, wherein said two hot rollers are heated up to said hot rolling temperature, wherein said hot rollers are arranged with a mutual spacing, preferably adjustable, and with a pressure, preferably adjustable, between said two hot rollers directed towards their rotation axes in such a way that said at least one matrix passing through said hot rollers is simultaneously subjected to both heating and pressing.
  • the apparatus is characterised in that said arrangement for pressing said at least one matrix comprises at least one set of two cold rollers with parallel rotation axes and rotating in opposite directions with equal surface speed, wherein said cold rollers have a surface temperature, which is below melting tempera- ture of the materials in the weave, wherein said cold rollers are placed behind said hot rollers and arranged with a mutual spacing, preferably adjustable, and a pressure, pref- erably adjustable, between said two cold rollers directed towards their rotation axes in such a way that said at least one matrix passing through said cold rollers is subjected to additional pressing.

  • the apparatus is characterised in that the diameter of said hot rollers is between 300 mm and 500 mm, preferably between 350 mm and 450 mm, most preferably 400 mm. It is advantageous, that the hot rollers have a relatively large diameter, as it gives the possibility for the weave to get in contact with the rollers surface over a larger area, which results in a thorough penetration of heat into the mate- rial. With small diameters, for example 40 mm, the heat penetration into the material is so insufficient that there occurs a significant temperature difference between the surface of the formed composite sheet and the centre plane of the composite sheet. Due to the fact that during melting and pressing, the polymer must completely enclose the reinforcing threads, it is advantageous to use bigger rollers for contact heating of the weave.
  • the apparatus is characterised in that said hot rollers and or said cold rollers are provided as a solid of revolution with a surface profile deviating from cylindrical shape such that the resulting composite sheet is given a shape deviat- ing from a planar shape.
  • the apparatus is characterised in that said at least one arrangement for pressing said at least one matrix has an adjustable minimum opening for the passage of said matrix though this arrangement, wherein said minimum opening defines a limit for the pressing of said at least one composite sheet.
  • said at least one heating device contain at least one station with thermal radiation. Testing of the invention has shown, that heating of the weave with thermal radiation is not necessary. However, the invention is not restricted to not using this form of heating, and in special cases it may be an advantage to apply this heating stage.
  • Composite sheets produced in accordance with the invention can with advantage be used in complex structures, where the sheets are included as a replacement for aluminium sheets.
  • Composite sheets have better weight to stiffness ratio than aluminium sheets, and much higher impact strength. These parameters are often key components for the selection of the material.
