- Figure 11 schematically shows the flow of hot air inside the mold during the curing process.
- a wind turbine blade known in the art is constituted by a structural beam 1, an upper shell or extrados 44 and a lower or intrados shell 45.
- the structural beam 1 is formed by a first body or root body 2 and a second body or trunk body 3.
- the root body 2 is formed by a cylindrical first part 4, a second transition part 5 and a third part 6 in the form of a drawer.
- the trunk body 3 is shaped like a drawer with a decreasing section towards the tip of the blade, having to support its upper face 7, which is in contact with the extrados 44, and its lower face 9, which is in contact with the intrados 45 , tensions higher than their lateral faces 11 and 13, during the life of the blade.
- the structural beam 1 is formed by a root body 2 properly structured to fulfill the functions of fixing the blade to the wind turbine hub and supporting and transmitting the maximum loads to which the Ia is subjected blade by the action of the wind, and by a body-trunk 3 constituted, as shown in Figure 3, by several batteries 26 each formed by several layers of carbon fiber impregnated with synthetic resin 14 located in the upper areas 7 and lower 9 of the beam, interspersed between several layers of fiberglass impregnated with synthetic resin 15 arranged throughout its surface, as well as by a layer of reinforcing material 16 on each side of the beam, these reinforcing layers being fixed vertically to the beam by means of resin sheets, and then wrapping it with resin adhesive film.
- a root body 2 properly structured to fulfill the functions of fixing the blade to the wind turbine hub and supporting and transmitting the maximum loads to which the Ia is subjected blade by the action of the wind
- a body-trunk 3 constituted, as shown in Figure 3, by several batteries 26 each formed by several layers of carbon fiber impregnated
- the surface of the mold 21 represented in Figure 5 is prepared, which will be used for the manufacture of the beam 1 with a treatment of mold release liquids that will facilitate the subsequent operation of extraction of the beam 1.
- fixing elements 56 are placed that will serve as a connection with the systems of support 57, 58 and 59 of the mold 21.
- These support systems are of the retractable type, so that they will allow the passage of a winder 47 in the winding process, as will be explained later.
- the mold 21 In the rolling position the mold 21 will be supported in its end parts, by means of an articulated support 10 and a recessed support 13, both of which allow rotation in the axial direction of the mold.
- the support of the mold 21 by the supports 57, 58 and 59 will be carried out by means of articulated supports.
- the body 2 is introduced therein to its end 13, fixing it by means of a screw connection with threaded metal inserts to the element 18, which will be used for the demoulding operation at the end of the procedure.
- the rolling of the beam 3 is carried out, that is to say the successive application of layers of carbon fiber and resin, 14, and layers of fiberglass and resin, 15.
- the mold 21 To laminate the beam 3, the mold 21 must be resting on the three supports of retractable type 57, 58 and 59, and supported on the tip by a support called giraffe, 10, as shown in Ia
- the start of the rolling process consists of winding several layers of fiberglass 15 on the mold 21 in the previous position, using a winder 47, which has a side fences 20.
- the layers are formed by fabrics 8, overlapping each other longitudinally, between 10 and 20 mm, with the glass fibers oriented +/- 45 ° approximately with respect to axis 12 of beam 3.
- the layers of carbon fiber 14 are laminated by means of an automatic laminating wrapping machine 24 provided with a head 22 and fed by a carbon deposit 23, until reaching the connection radius 37 with the parties sides 39 of the mold 21.
- the layers 14 are formed by fabrics 49 that do not overlap each other.
- the supports 57, 58 and 59 are removed, and the mold 21 is rotated 180 °, subsequently replacing the supports, placing another stack 26 on the surface 36 of the mold 21 (previously located in its lower part) .
- a predefined number of batteries 26 must be placed depending on the stiffness that is to be achieved on the upper 7 and lower 9 faces of the beam 3.
- the curing preparation operation consists of completely covering the beam 3 and the previous mold 21 with a closed vacuum bag, 31, which is connected to a vacuum pump, reaching, for this Concrete embodiment of the invention, a vacuum pressure of between -0.7 and -0.8 bar, a minimum pressure of -0.7 bar being maintained throughout the curing process.
- a peelable film 28 is placed on the beam 3, which, when removed, will leave a clean and rough surface that will facilitate the subsequent adhesion of other elements (when forming the complete blade) and a vacuum bag 31
- This vacuum bag 31 encloses: an aerator 30, formed by a spongy fabric that allows the passage of air, so that it distributes the vacuum evenly on the surface of the laminate; and a bleed 29, formed by a perforated plastic film, with a certain hole density, which facilitates the flow of resin to the outside, eliminating the air content within the laminate of composite material and also eliminating the excess resin contained in The fiber since, with exceptions, the prepreg always contains a surplus of resin.
- the curing process consists of drying, by means of the application of a hot air flow, of the fabrics stacked on the mold 21 during the rolling process, so that they acquire the definitive morphology of the beam 3.
- the curing is carried out both from the outside, by means of blown air in the curing stoves 25 that appear in Figure 4, as well as inside, as can be seen in Figure 11.
- the interior of the beam 3 cures thanks to the internal channels that the mold 21 possesses, in which hot air 34 is introduced - with the optimum flow, pressure and temperature regimes for the correct curing of the beam 3 - from the system of heating 19 of Figure 3, through the discharge conduit 32 of the mold 21. Said conduit is drilled so that the hot curing air passes to the extraction conduits 33.
- the beam 3 acquires its definitive form, so it is important to minimize its deflection during this part of the process.
- the beam 3 cures in a position in which the support of the mold 21 during curing is carried out by means of two leveling screws that are screwed to the supports, located in areas of the mold prepared for said function. These leveling screws are anchored to the curing stoves 25, in their inner zone.
- the demolding process consists in the extraction of beam 1 after having acquired its morphology and its final mechanical properties.
- the curing stoves 25 to proceed with the demoulding, the curing stoves 25 must first be removed, and then two slings linked to a crane bridge must be placed. Then, the support of the pointed mold 10 is removed.
- the body 2 of the beam is fixed in its circular end part by means of a screw connection with threaded metal inserts to the demoulding or extraction system 18 so that, while the body 2 is fixed to a movable flange, the mold 21 is fixed in its end 13 to a static flange.
- the finished beam 1 is ejected, the movement of the slings of a standard crane bridge accompanying its movement.
- a cooling station (not shown), in which it is ensured that its final shape is as desired.
