Definitions

  • the invention relates to a cylindrical mast element, which can be joined end to end to other similar elements, in order to constitute a mast.
  • the inclination of the contact surfaces of two elements nested can vary between fifteen and forty five degrees, which ensures in good conditions the relative positioning in rotation.
  • Such elements are generally produced by polymerization of a thermosetting resin reinforced with fibers, for example glass or carbon fibers.
  • One of the aims of the present invention is to remedy this drawback and to propose a mast element which has a reinforced structure, in particular at the level of the end in question.
  • Another object of the present invention is to provide a mast element whose longitudinal structure is also reinforced.
  • the mast element is cylindrical and carries at one of its ends a sleeve for its engagement in the other end of a similar element.
  • Its wall is formed by winding successive pieces of fabric impregnated with a thermosetting resin, the whole then being polymerized; at least some of the fabrics are made of fibers that are warped and woven in a different tightness to provide a sense of greater strength. It is characterized by the fact that, relative to the rest of the element, in an area close to its bevelled end, opposite the sleeve and corresponding to the fitting area of a similar element, it comprises at least one additional piece of fabric which offers its greatest resistance in the direction transverse to the mast.
  • one of the ends of the element for example the end 4, is extended by a cylindrical sleeve integral with this end 4.
  • the sleeve 5 is intended to be engaged in the opposite end of another element (not shown), which end is for this purpose similar to the end 6 of the tube 2.
  • the external dimensions of the sleeve 5 and the internal dimensions of the end 6 correspond, so as to allow engagement of the sleeve 5 inside the end 6.
  • the element 1 also has at each of its ends flat surfaces and inclined relative to the axis 3 of the tube.
  • the contact surfaces 7 and 8 ensure a rotational positioning of two elements placed end to end.
  • the wall 1 is formed by winding pieces of technical fabric impregnated with a thermosetting resin, the whole then being polymerized.
  • At least some of the pieces of fabric are made of fibers which are weft and warp tight. differently to present a sense of greater resistance.
  • all the pieces are oriented so that their direction of greatest resistance is parallel to the longitudinal axis.
  • the zone 9 located at the beveled end 6 of the tube 2 comprises at least one additional piece of fabric oriented so as to present its greatest resistance in the transverse direction of the mast.
  • the zone 9 extends approximately at the end 6 of the tube 2, from the contact surface 8 over a length which corresponds substantially to the depth of fitting of an element placed end to end.
  • the length of the area 9 is slightly less than the depth of the fitting area.
  • Figure 2 There is shown schematically in Figure 2 the different pieces of fabric of the structure of the element.
  • the parts identified in 15, 16, 17 and 19 are oriented so as to have greater resistance in one direction than in the other.
  • the parts 15, 16, 17 are oriented so that their direction of high resistance is parallel to the longitudinal axis and the part 19 is on the contrary oriented so that its direction of greatest resistance is transverse to the mast .
  • the dashed line 18 shows diagrammatically the axis of the tube, and therefore the layer 10 is the internal layer of the wall of the tube.
  • the balanced parts and the oriented parts are alternated, at least in the internal part of the tube.
  • the outer layer 14 is indeed similar to layer 13.
  • This layer is a surface layer and has a lesser thickness.
  • the inner layer that is to say layer 10
  • the inner layer is a balanced layer.
  • the reversal of the direction of greater resistance, in the zone 9 of the tube 2 is carried out at the level of one of the first layers of oriented fibers and, preferably, of the first, that is to say at the level of the layer 15.
  • the pieces of fabric as well as the thermosetting resin which binds them are of an appropriate nature but preferably, an alternation of layers of glass fibers and layers of carbon fibers will be used, the layers of glass fibers lying superficially and therefore will form the inner surface and the outer surface of the wall of the tube while the layers of carbon fibers will be embedded between these layers of glass fibers.
  • Glass fibers indeed have better impact resistance than carbon fibers which are more fragile to impact but which have superior mechanical qualities and in particular better resistance to bending and are therefore extremely advantageous.
  • the tubular wall has a chamfer 20 eliminating the acute angle due to the bias cut, which prevents the deformation of the end 6.
  • a mast element has been produced, the length of the tube 2 of which is approximately one hundred and forty centimeters, the end of which is extended by a sleeve of approximate length of twenty centimeters, having an outside diameter of approximately one hundred millimeters.
  • the wall of the tube 2 is made up of eight pieces of fabric respecting the alternation of oriented pieces, balanced pieces according to the arrangement described in relation to FIG. 2.
  • the so-called balanced pieces have approximately the same weight of warp and weft fibers, but one of them, for example the warp, may reach around fifty five percent of the total weight which will in any case be around two hundred grams per square meter. .
  • the so-called oriented pieces have, approximately in the direction of greatest resistance such as that of the warp, a proportion of fibers of eighty-nine percent of the total grammage which will be approximately three hundred grams per square meter.
  • this inversion was carried out initially over a length of around one hundred and seventy millimeters when the raw tube was produced.
  • this length has been reduced between approximately one hundred and twenty and one hundred and fifty millimeters.
