Definitions

  • the present invention concerns a method of production of composite plates as described in the introductory part of claim 1.
  • the invention also concerns an apparatus for production of composite plates, a matrix of fibre, a composite plate, a tubular composite plate, a product containing a composite plate and a method for post-forming of a composite plate.
  • fibres are to have certain preferred directions, for example, lie at certain angles with respect to the direc- tion of web in the production.
  • Such fibre matrices are called web. This term covers not only woven matrices but also matrices where long fibres in array are assembled by stitching.
  • web is used for long fibre composites as opposed to "non- woven" materials which are mixtures of short fibres and are used, for example, for insulation mats.
  • a so-called belt press In order to produce composite plates in great lengths, a so-called belt press can be used, which is known e.g. from WO 97/26397.
  • a matrix of fibres is passed through a heating process and a pressing process, where the pressing process takes place between pressure rollers with belts running around them in such a way, that composite plate is produced as lengths between the belts on each side of the plate.
  • belt presses are very expensive machines, why other apparatuses have been developed for the production of composite plates in web form without using belts around the rollers. These apparatuses cost only a small fraction of the corresponding belt presses.
  • This method has some disadvantages.
  • To achieve a complete melting of web it is exposed to a strong thermal radiation on a preheating stage.
  • the disadvantage of this preheating stage is that a temperature is reached on the external side of the web, which is close to decomposition temperature for the polymer, for example, 230°C for poly- propylene, abbreviated PP, while the temperature in the center of the web is much lower, for example, 140°C, and often below melting point, which for PP is 165°C. Consequently, the web undergoes a decomposition of external polymer fibres, which is very undesirable but accepted in order to obtain the necessary preheating for the final temperature at which the polymer melts to consolidate the composite plate.
  • Another disadvantage is lack of homogenization in the material when the web initially is heated to the melting temperature and then pressed at a lower temperature. Homogenization is the process in which the polymer melts completely and then settles, enclosing the reinforcement material.
  • the prior art methods have to run at a relatively high speed in order to minimize the time span between the heating and the subsequent pressing with cold rollers. But at high speed it is impossible to heat the web up to the correct working temperature, which is somewhat higher than the melting temperature and preferably close to decomposition temperature. This is one of the reasons why the thermal radiation preheating stage is used in the prior art methods and systems. It has, however, not been possible to solve this problem completely as high process speed results in poor preheating and unsatisfactory homogenization of the material, while slow process speed results in better heating but, on the other hand, it takes long time for the web to reach the pressing rollers why the pressing takes place at too low temperature, also resulting in unsatisfactory homogenization.
  • the purpose of this invention is to provide a method and an apparatus for production of composite plates from the web, where the above described disadvantages are avoided, and where preheating of web by thermal radiation is not necessary.
  • matrix of fibres a composite which can include short, non-woven fibres that are stitched or pressed together, and/or long fibres, woven or sewn together.
  • the invention will be explained with a composite web as an example, which however shall by no means delimit the invention to not being applicable with so-called non- woven matrices of fibres.
  • Temperature action for the production of composite plates is achieved by heat transfer from an electrically conducting web or fibre forming part of composite matrix and which is heated by means of electric current.
  • the current conducting fibres may, for example, form part of the matrix during the production of the matrix, but it is also possible to put these fibres or stitch them into the matrix subsequently.
  • conducting fibres which are commercially available. These conducting fibres, which are e.g. used for heating clothes, can be heated up to above 200°C, even up to 400° C, which makes them suitable for heating the web. If the matrix is heated to a temperature above the melting point for the polymer in the matrix, for example 200° C for polypropylene, conducting fibres will melt together with the polymer and possible other fibres in the matrix. It is assumed that melting temperature of conducting fibres is higher than melting temperature of the polymer in the matrix.
  • the web is heated up and pressed at a temperature where at least one, however preferably one, of the composite materials are mel- ting.
  • the composite is made of polymer fibres, which by melting settle around reinforcing fibres, such as glass, and other fibres in the composite, if any. Pressing may occur by placing the web, which is at a temperature higher than the melting temperature of the polymer, between two press plates, which are then moved to- wards each other until a predetermined distance. The composite plate formed thereby will then assume this predetermined dimension at the most.
  • pressing can be performed by leading the web between a pair of rollers adjusted to a certain distance or a certain pressing force whereby the composite plate is formed as a long web which after cooling, when the polymer has set or hardened, can be rolled together, depending on the flexibility, for further transport.
  • Heating of the web which occurs by conducting current through the web, can be achieved by conveying the web over a first and a second roller with electric potential bet- ween these rollers for conduction electric current through the conducting fibres in the web between the first and the second roller.
  • Such two rollers which are acting as electrodes, can with advantage be used respectively before and after the press mold. It is, however, also possible that electric potential is established between a first roller and the press mold itself.
  • the web can be formed in different ways and may comprise fibres of PP, PET or
  • PTFE as well as fibres of reinforcing material, such as glass fibre, carbon fibre, ara- mide fibres, kevlar fibres, metal fibres, carbon coated glass fibres, vegetable fibres and other organic fibres, or synthetic fibres.
  • the web according to the invention also contains current carrying fibres.
  • Such current carrying fibres in the web can, for example, be carbon fibres or metal fibres woven or stitched into a web of polymer fibres and reinforcing fibres, preferably glass fibres. It is also possible, however, for reinforcing fibres to act as current conducting fibres. Carbon fibres can, for example, constitute the reinforcing material. But also glass fibres as reinforcing material can be made conducting by coating their surface with a conducting material. The web has proved to be particularly usable if the share of reinforcing fibres in the web is between 40% and 80%, preferably between 60% and 70%, and most preferred 60%.
  • Cooling of the web after pressing can be performed in different ways, but it is preferred that the web is cold pressed by at least one rotating cold roller.
  • the roller acts as an additional mould for the composite plate where, for example, the surface of composite plate can be structured.
  • Such structuring in which embossing of the surface may form a part in the shape of, for example, patterns or logos, may, however, be done during pressing in hot condition.
  • the matrix has been supplied with contact tracks, e.g. alongside the track, for electric contact with skates (like collector shoes) or rollers suited for this purpose.
  • Examples of applications, where subsequent heating is desirable, are especially those when the composite has to be post-formed, i.e. formed after actual production of con- solidated composite.
  • the composite is heated to a temperature below melting point, yet high enough for plastic deformation of the composite.
  • a differentiated forming may be performed as these areas will be softer than the others.
  • Heating of the composite is also a useful property of a composite according to the invention.
  • such a composite can very easily be kept frost-free in cold areas, for example, if used for feed or drinking troughs in outdoors farming of domestic animals in the winter time.
  • the composite can be very usable for rooms requiring heating and particularly if a very uniform heating is required without significant temperature gradients.
  • Another application of the composite is on inside walls of caravans or railway cars, which are known for lack of comfort in cold seasons as the walls are cold.
  • the inside walls can be heated up in a simple way, thus avoiding such discomfort.
  • One more application of the conductive composite material is to use it as a screening wall for electronic equipment, for example in mobile or stationary military installations.
  • Such screening can, for example, be used for protection from tapping.
  • the composite web it is further possible to add a surface layer on the composite web, for example, a synthetic material or metal layer.
  • a surface layer on the composite web for example, a synthetic material or metal layer.
  • the surface of the composite web can be structured if this is suitable.

  • the matrix 1 is made with three contact tracks, namely two contact tracks 11, 11' along the sides and a third track 11", for example, in the middle of composite web 1.
  • Diagonal wrapping allows contact tracks 11, 11' to be in contact with each otlier. Passage of current through the matrix is then achieved by the power source suitably contacting the central contact track 11" and at least one of contact tracks 11, 11' at the sides of the matrix.
  • local heating of pipes can be appropriate for bending or other adjustment of pipes during installation.
  • Heating the composite with conducting fibres can also be supplemented with techniques comprising magnetic induction, where the current is induced in the conductive fibres by means of varying magnetic fields.
  • the advantage of such forms of technique is that there is no need for contact, for example, by means of contact tracks.
  • such heating does not require the conductive fibres to be oriented in a certain direction or to have a certain pattern.
  • thermosetting composite plates have been explained in connection with webs containing a thermoplastic polymer. It is, however, within the ability of the skilled in the art to utilize the invention by using hot fibres in thermosetting composite plates.
