<p>The invention relates to a process and a device for making plates of polymeric composite materials such as polyester, epoxy, phenolic, vinylester resins or other polymers, reinforced with fabrics made of glass fibers, carbon fibers, aramidic fibers and the like. According to the invention, the process consists in laying the composite material (3) in non-polymerized condition onto the surface of a plane mould (2), coating the same with a plastic foil (4), pressing the composite material (3) onto the mould (2) by means of a pressing device with cylinders (5) which removes the excess of composite material (3) towards the mould edges so that, by reducing the volume of composite material (3) under the plastic foil (4), there is formed a vacuum pressure which presses the composite material (3) during the entire polymerization process, and, in the end, the resulting plate of composite material is removed from the mould and the plastic foil (4) is eliminated. According to the invention, the device comprises a roller working table (1) whereon there moves the plane mould (2) with the composite material (3) covered with the plastic foil (4) and a pressing device with cylinders (5).</p> |
