Definitions

  • the present invention relates to a filament winding device and to a filament winding process.
  • filament winding refers to a particular production technique enabling hollow articles of composite material to be manufactured, which articles have an axially symmetric geometry such as poles, bottles, tanks, pipes and the like.
  • This technology consists in laying down filaments, in the form of a single fibre, fabric bands or ribbons, around a rotary mandrel suitably shaped depending on the geometry of the finished product that is wished to be obtained.
  • the filament winding devices of the known art comprise a mandrel having an axially symmetric geometry and driven in rotation around a horizontal axis coincident with the extension axis of the mandrel itself.
  • the mandrel is supported and set in rotation by a frame only acting at the mandrel ends in such a manner as to enable the side surface of the mandrel to be completely accessible.
  • a horizontal guide is present close to the rotary mandrel, which guide slidably supports a laying head that, picking up one or more filaments from respective reels, lays them down on the side surface of the mandrel.
  • the continuous rotation of the mandrel causes winding of the filaments on the side surface of said mandrel .
  • the filaments are wound up on the surface of the rotary mandrel following a scheme that is established based on the mechanical and structural features that the final product must have.
  • the laid filaments before or after their being laid down on the mandrel, are impregnated with one or more catalysing resins so that they are buried in a matrix of binding material.
  • the mandrel When winding has been completed, the mandrel is stopped and left to its horizontal position until the composite material consisting of the filaments buried in the binder matrix fully surrounding the mandrel, is consolidated.
  • the composite material once consolidated, is slipped off the mandrel forming the desired hollow manufactured article having an axially symmetric shape and size.
  • the mandrel also tends to bend during the filament winding step. This gives rise to an uneven thickness distribution in the wound filament, or at all events a thickness distribution different from the desired one, thereby significantly altering the mechanical and structural features that the final manufactured article must possess.
  • the main technical task of the present invention is to make available a filament winding device and a filament winding process that are not affected by the drawbacks highlighted above.
  • FIG. 1 is a perspective view of a filament winding device in accordance with the present invention.
  • a filament winding device in accordance with the present invention has been generally identified with reference numeral 1.
  • Device 1 comprises a forming station and a consolidation station.
  • a manufactured article (shown during the manufacturing step in Fig. 1) is formed, while in the consolidation station the manufactured article thus obtained is consolidated, i.e. it takes its final mechanical and structural features.
  • distinction between forming station and consolidation station can be also physical, in addition to being functional, which means that the two stations can also be distinct from each other and mutually spaced apart.
  • device 1 comprises a mandrel 2 having a symmetry axis S that is coincident with the major extension axis of mandrel 2. It will be recognised that by the term mandrel it is intended, in the technical field of the present invention, a member serving as a support for the manufactured article to be made. This member further has the function to transfer a predetermined shape to the manufactured article to be made, as better clarified in the following.
  • Mandrel 2 in the embodiment shown in Fig. 1 is a cylinder.
  • mandrel 2 can be of any other shape provided it has an axial symmetry.
  • Device 1 further comprises a supporting frame 3 for said mandrel 2 and a laying head 4 acting on mandrel 2.
  • the laying head 4 has the function to lay down one or more filaments 101 on the side surface 5 of mandrel 2, which filaments once they have been wound up around the side surface 5 of mandrel, 2 will constitute the manufactured article.
  • Filaments 101 can be, alternatively or in combination, either single fibres, such as glass fibres for example, or fabric bands or ribbons. Fibres 101 are impregnated with a catalysing resin or a thermoplastic material before or after their being laid down on the side surface of mandrel 2. The catalysing resin, once hardened in the consolidation station, forms a binder matrix for the filaments that are buried therein, thus obtaining a manufactured article of composite material.
  • thermoplastic material If fibres 101 be impregnated with a thermoplastic material, the latter is activated by a heat source at the end of winding, so as to consolidate the manufactured article. - Q -
  • mandrel 2 is retained in a vertical position during its rotation, so that it does not bend during laying of the filaments even if said mandrel 2 is very long, i.e. has a length measured along its symmetry axis S, exceeding 12 metres for example.
  • the vertical position of mandrel 2 ensures that the combination of the weight force resulting from the mass of the mandrel and the weight force of the filaments that are progressively wound up around said mandrel does not create shearing stresses in mandrel 2 of an amount sufficient to cause bending of the mandrel itself.
  • mandrel 2 carries out a translation in a vertical direction during winding of filaments 101 on its surface 5. In this manner the laying head 4 can be greatly simplified.
  • connection between the laying head 4 and reels 7 from which the filaments are picked up is particularly simplified.
  • the laying head 4 comprises a hollow disc-shaped member 8 fitted on mandrel 2.
  • the hollow member 8 is connected to the plurality of reels 7 and picks up therefrom, the filaments 101 required for carrying out winding on mandrel 2. Laying of the filaments picked up from reels 7 on the side surface 5 of mandrel 2 takes place by suitable means acting on the hollow member 8, which means is known and therefore not shown or further described.
  • the supporting frame 3 comprises a fixed portion 9 and a movable portion 10.
  • the fixed portion 9 is integral with a base 102, the slab of a building for example, and comprises a vertical guide 11 for the movable portion 10.
  • the latter carries out a translation along the vertical guide 11 and comprises two tailpieces 12 engaging mandrel 2.
  • At least one of the tailpieces 12 is provided with a driving member 13, preferably of the electric type, setting mandrel 2 in rotation along its symmetry axis S.
  • frame 3 occupies several storeys of the same building.
  • the preferred embodiment of the present invention contemplates installation of frame 3 on the slab of a floor in a building and continuation of frame 3 on the floor above, after drilling the slab of said floor.
  • the portion of device 1 extending under base 102 that can be either a lower floor or a hole in the ground, should the binder matrix be a thermoplastic material, comprises a furnace for activation of said thermoplastic material.
  • a furnace for activation of said thermoplastic material comprises a furnace for activation of said thermoplastic material.
  • both the movable portion 9 and fixed portion 10 of frame 3 can be made with a lattice structure covered with a metal structure to protect the latter against weathering.
  • device 1 can be also placed at the outside of a building.
  • mandrel 2 In use, mandrel 2 is set in rotation around its symmetry axis S. As said, mandrel 2 lies in a substantially vertical position.
  • the laying head 4 picks up the filaments 101 from reels 7 and lays them down on the side surface 5 of mandrel 2.
  • Mandrel 2 during its rotation is also translated in a vertical direction in such a manner that its side surface 5 is covered with several passages of filaments 101.
  • the laying head is maintained to a fixed position, i.e. it carries out no translation relative to the fixed portion 9 of frame 3.
  • mandrel 2 When the resin has hardened at least partly, rotation of mandrel 2 is stopped too. Irrespective of whether the forming and consolidation stations are coincident or not, mandrel 2 is maintained to the vertical position (as specified above) , until complete hardening of the binding-material resin that consolidates.
  • the manufactured article is removed from one end of mandrel 2 and is therefore ready for further working operations (painting and the like) or for installation.
  • the invention achieves the intended purpose.
  • manufactured articles in one piece can be made which have any longitudinal size, i.e. along the axis of symmetry, a size longer than 12 metres for example .
