Description

Technical Field

[0001] The invention relates to a method for producing a fiber composite component, wherein the fiber composite component has a base section, a connecting section with a curved cross section adjoining the end of the base section, and a connecting element for fastening the fiber composite component to a superstructure. The invention also relates to a method for producing a fiber composite hollow component.

[0002] The invention further relates to a wind power generation device having a plurality of rotor blades. Background Art

[0003] Due to the high specific strength, fiber composite components have the property of having particularly high strength and stiffness in the direction predetermined by the fiber arrangement of the fiber material at a relatively low weight. Therefore, such fiber composite components are particularly suitable for lightweight construction in order to save energy. Therefore, the use of fiber composite components is becoming more and more popular not only in aerospace, but also in the automotive industry and renewable energy technology, such as wind turbines. There, for example, the rotor blades of wind turbines are made of fiber composite materials.

[0004] The fiber composite component is made of a fiber composite material having a fiber material and a matrix material. The fiber material is embedded in the matrix material so that it forms an integral unit with the fiber material by hardening the matrix material. In particular, carbon fibers or glass fibers are used as the fiber material, and in particular, thermoplastic and thermosetting matrix plastics are used as the matrix material. In addition to the fiber material and the matrix material, the fiber composite material can also contain other materials. In the sense of the present invention, the fiber composite material is also understood to be a fiber composite-hybrid material, which, for example, has an additional metal layer or metal foil (such as GLARE).

[0005] In principle, fiber composite components have the disadvantage that their strength and stiffness only act optimally in the fiber direction, and that connection arrangements with forces acting orthogonally to the fiber direction quickly lead to failure of the connection arrangement. In bolt connections, a three-dimensional stress state usually exists, so that here, too, the fiber composite component is strongly loaded orthogonally to the fiber direction and in the thickness direction. As a result, fiber-plastic composites have a lower wall strength than components made of isotropic materials. In order to achieve optimal strength in the connection area, the connection area must be thickened by additional fiber material layers, which leads to higher production costs and is also contrary to the concept of lightweight construction.

[0006] A composite material with a reinforced connection region is known from EP 1 082 217 B1. The connection region consists of multiple layers of fiber material, wherein one or more layers of reinforcing material, such as titanium, are arranged between the multiple layers of fiber material. This makes it possible to increase the hole wall strength when openings are introduced in the connection region as connection elements. A similar material structure with alternating layers of fiber material and metal material can be found, for example, in DE 10 2010 035 324 A1.

[0007] Precisely in wind turbines, safe connection technology is required in order to connect the rotor blade at its blade root to the hub of the wind turbine (blade interface) or to connect two blade sections to one another. In practice, a T-bolt threaded connection is often used, which consists of longitudinal bolts and transverse bolts that are screwed together. The transverse bolts conduct the loads through the hole walls to the corresponding holes in the laminate (hardened matrix material with embedded fiber material) of the rotor blade in the connection area. However, the hole wall strength of conventional laminates made of glass fiber reinforced plastic (GFRP) is low, so that a large wall thickness is required in the connection area of ​​the blade root in order to be able to safely transmit high loads.

[0008] Similar to the teachings of EP 1 082 217 B1 and DE 10 2010 035 324 A1, there is now the possibility of using fiber-metal hybrid materials locally in the connection region of the blade root of a rotor blade for increasing the load-bearing capacity of the blade root in order to achieve a significantly higher hole wall strength than conventional laminates due to the metal content.

[0009] However, it is disadvantageous that such fiber-metal hybrid materials with thick metal sheets are difficult to be reliably formed into curved shapes. If the fiber layer is to be replaced by a metal layer consisting of a metal material in the connection area, a corresponding layer thickness of at least 0.5 mm is required. However, such a metal layer (metal sheet) has a relatively high bending stiffness, which makes it difficult to deposit into a curved shape. The pressure of compressing each layer in the vacuum injection method may no longer be sufficient to adjust the curved shape. In addition, pressure balance will occur during injection, wherein the rebound of the metal sheet will be expected. Although the problem of the high bending stiffness of the metal layer in the fiber-metal hybrid material can be overcome by using a closed shape or using many thin metal sheets, this will lead to significantly higher manufacturing costs. Closed molding tools have significantly higher tool costs, and the use of many thin metal sheets also requires the use of thinner fiber layers, which will make the resin flow difficult and only a small injection path can be achieved.

[0010] A further disadvantage is that the holes required for the connection can only be introduced into large curved components in the relevant regions made of fiber-metal hybrid material with great effort, which makes the production process more complicated. Summary of the invention

[0011] It is therefore an object of the present invention to specify an improved method for producing a fiber composite component which is bent in the connection region and has a particularly high cell wall strength.

[0012] This object is achieved according to the invention by means of a method according to claim 1. Advantageous embodiments of the invention can be found in the respective dependent claims.

[0013] According to claim 1, a method for producing a fiber composite component is provided, wherein the fiber composite component has a base section, at the end of which a connecting section with a curved cross section adjoins, the connecting section having a connecting element for fastening the fiber composite component to a superstructure. The method comprises the following steps:

[0014] - providing a plurality of elongated fiber-metal hybrid sections, which are composed of fiber material layers having fiber material and metal layers having metal material, which are arranged alternately one above the other,

[0015] - introducing the respective elongated fiber-metal hybrid section into the connecting section of the fiber composite component to be produced in a forming tool, so that the end faces of the fiber-metal hybrid section form the cross-sectional plane of the fiber composite component to be produced,

[0016] - introducing the fiber material into a forming tool, and

[0017] - Hardening of the matrix material infused into the fiber material.

[0018] Therefore, it is proposed that a plurality of elongated fiber-metal hybrid sections are first provided, which are composed of fiber material layers with fiber material and metal layers with metal material arranged alternately on top of each other. Each of these sections is composed of alternating layers of fiber material and metal material and has a particularly high hole wall strength. These sections are now used to form the connecting section of the fiber composite component to be manufactured. For this purpose, each section is introduced into a forming tool, that is, the position where the connecting section of the fiber composite component to be manufactured is located. In addition, the fiber material of the fiber composite material is introduced into the forming tool, and the fiber composite material has a fiber material and a matrix material embedded in the fiber material, so as to manufacture a fiber preform from the fiber material and the section in the connecting section. The matrix material injected into the fiber material is then hardened to manufacture the fiber composite component. Here, it is particularly preferred that these sections are embedded in the fiber material on both sides, that is, not only on the outside of the component but also on the inside of the component.

[0019] In this case, the individual segments are not curved in width in particular and, in a preferred embodiment, are already hardened, ie the matrix material introduced into the fiber material of the fiber material layer of the segment is already hardened.

[0020] The segments form a curvature in the connecting section, wherein the end faces of the segments form the cross-sectional plane in the connecting section. The elongated side faces each adjacent segment, wherein the lower surface faces the outer side of the fiber composite component and the upper surface faces the inner side of the fiber composite component.

[0021] Adjacent sections can here be directly adjacent to one another via their elongated sides or can be filled between these sides with a corresponding filling material, for example with a matrix material of a fiber composite material or a wedge (for example made of a plastic material such as PET, PU or also in the form of a foam wedge made of such a plastic material).

[0022] By segmenting, the individual segments can be produced in particular without bending over their width, so that the problem of high bending stiffness of the metal layer of the fiber-metal hybrid material need not be taken into account. For example, a metal layer with a thickness of at least 0.5 mm can be used.

[0023] The fiber material of the fiber composite material for producing the fiber composite component can be a dry fiber material or a pre-impregnated fiber material. In the case of a dry fiber material, the matrix material required for the fiber composite material is injected into the fiber material forming the fiber preform at a later point in time. The injection can be carried out, for example, by means of a vacuum injection method. However, it is also conceivable to use pre-impregnated fiber materials (so-called prepregs), in which the fiber material is already impregnated with the matrix material.

[0024] It is conceivable to use the same fiber composite material for the fiber-metal hybrid sections, which is also used to produce the entire fiber composite component with the sections. However, it is also conceivable to use only a different matrix material for the sections. It is also conceivable to use a different fiber material for the sections. It is thus conceivable to produce the sections from a glass fiber material layer and the remaining components from carbon fibers.

[0025] Steel is particularly suitable for the metal layer. For wind energy applications, the combination of glass fiber reinforced material (GFK) and steel is particularly advantageous, since a good cost-benefit ratio exists here. Alternatively, titanium can also be used, which has higher costs and improved properties. Combinations of carbon fiber reinforced material (CFK) and steel or CFK and titanium must also be emphasized.

[0026] According to one embodiment, provision is made for the elongated fiber-metal hybrid sections to be provided by arranging fiber material layers and metal layers alternately one above the other in each individual fiber-metal hybrid section and by hardening the matrix material introduced into the fiber material.

[0027] This means that the required elongated fiber-metal hybrid section is produced before the fiber composite component is produced, for example by alternately introducing individual fiber material layers and metal layers into a forming tool and then hardening the matrix material of the fiber material layers. Pre-impregnated fiber materials and dry fiber materials can be used here by means of a subsequent injection process.

[0028] According to one embodiment, elongated fiber-metal hybrid segments are provided by first producing at least one flat, unbent fiber-metal hybrid plate in which fiber material layers and metal layers are alternately arranged one on top of the other and a matrix material injected into the fiber material is hardened, wherein, after the fiber-metal hybrid plate is produced, the fiber-metal hybrid plate is divided into a plurality of individual elongated fiber-metal hybrid segments.

[0029] It is therefore proposed to first produce a flat, non-curved fiber-metal hybrid plate from a fiber-metal hybrid material and subsequently to separate it into a plurality of individual elongated fiber-metal hybrid segments (segments for short).

[0030] The separation is preferably carried out by water jet cutting. Cutting the metal layer by milling or sawing has the disadvantage that the matrix material (eg epoxy resin) contained in the fiber composite material is subject to degradation due to the heat generated when cutting the metal layer.

[0031] In the production of fiber-metal hybrid panels, dry or pre-impregnated fiber materials of fiber composite materials can also be used. If dry fiber materials are used, the stack consisting of fiber layers and metal layers must then be impregnated with matrix material, wherein the fiber layers are in particular soaked here. It is also conceivable to use pre-impregnated fiber materials as fiber layers.

[0032] It is conceivable to use the same fiber composite material for the fiber-metal hybrid plate, which is also used to produce the entire fiber composite component with the sections. However, it is also conceivable to use only a different matrix material for the hybrid plate. It is also conceivable to use a different fiber material for the hybrid plate. It is thus conceivable that the sections are produced from a glass fiber material layer, while the remaining components are produced from carbon fibers.

[0033] According to one embodiment, the connecting elements are introduced or arranged in the individual segments or before the segmentation of the at least one fiber-metal hybrid plate.

[0034] Such connecting elements can be, for example, openings in the segments. The openings are used here to mount the component on the superstructure by means of bolts. The openings can be introduced into the already segmented segments or before the mixing plate is segmented. The introduction of such openings into the segments or mixing plates can be carried out, for example, by means of water jet cutting.

[0035] According to one embodiment, at least one fiber material layer is introduced into the connecting section in the forming tool before the fiber-metal hybrid segment is introduced into the forming tool, wherein the fiber-metal hybrid segment is then placed onto the at least one fiber material layer.

[0036] The fiber material layers, preferably a plurality of fiber material layers, from the fiber composite material for the component thus form the outer layer of the fiber composite component. The segments are now arranged on this outer layer formed by the fiber material layers so that they become an integral component of the fiber composite component to be produced. In this case, openings already present in the segments can be omitted at corresponding locations in the fiber material layers of the outer layer.

[0037] According to one embodiment, after the fiber-metal hybrid section has been introduced into the molding tool, at least one fiber material layer is introduced into the connecting section in the molding tool, wherein the at least one fiber material layer is placed onto the fiber-metal hybrid section.

[0038] These fiber material layers, preferably a plurality of fiber material layers, from the fiber composite material for the component thus form the inner layer of the fiber composite component. In combination with the above-mentioned embodiment, the segment is thus embedded between the fiber material layers of the outer layer and the fiber material layers of the inner layer and can thus become an integral component of the fiber composite component.

[0039] According to one embodiment, it is provided that the fiber-metal hybrid segment is segmented in such a way that at least a portion of the fiber-metal hybrid segment has a trapezoidal cross section.

[0040] This is particularly advantageous in the case of circular or elliptically curved cross-sectional shapes, since adjacent segments rest with their side faces in an exactly fitting manner. For this purpose, the lower edge of the end face of the segment facing outward is longer than the upper edge of the end face of the segment facing inward, so that the adjacent segments follow the curvature predefined in the connecting section. Adjacent segments resting against each other with their side faces thus adjoin each other at an angle, so that the curvature in the connecting section can be approximated by the segments.

[0041] In order to achieve such a trapezoidal cross section, the segments formed by the mixing plate are divided at an angle, i.e., the mixing plate is divided, for example, by water jet cutting, so that the separating element (saw blade or water jet) is at an angle different from 90° transversely to the cutting direction. The angle depends on the curvature and the number of segments specified in the connecting section.

[0042] According to one embodiment, it is provided that at least one opening is introduced as a connecting element into at least a part of the fiber-metal hybrid section. This can be achieved, for example, by means of water jet cutting.

[0043] It is conceivable that the opening in the segment is first cut to a lower limit and only cut or milled to the final size after the fiber composite component is produced or after the matrix material has been injected into the fiber material of the fiber composite component. This has the advantage that by subsequently cutting or milling the fiber composite component, possible component deformations which occur, for example, despite the positional fixation during production can be compensated again by the high production accuracy of the cutting or milling.

[0044] Alternatively, it is also conceivable to first pre-cut the opening, for example by means of water jet cutting, and then mill the opening to the final size before it is integrated into the fiber composite component. This has the advantage that the hole in the segment is already introduced with high precision and the positional accuracy during injection is therefore also higher. In addition, milling small, flat segments is easier than milling large, curved fiber composite components.

[0045] According to one embodiment, a sleeve is inserted into each of the at least one opening of the fiber-metal hybrid section. The sleeve serves to improve the strength of the hole wall when a corresponding bolt is used for connection to a structure.

[0046] According to one embodiment, a molding tool is provided, in which a plurality of positioning pegs protruding from the molding tool surface are arranged in the molding tool surface, wherein when the fiber-metal hybrid segment is introduced into the molding tool, these positioning pegs engage in openings of the fiber-metal hybrid segment for fixing the position of the fiber-metal hybrid segment on the molding tool.

[0047] These positioning bolts in the molding tool surface are used to fix the individual segments in the molding tool at their corresponding predetermined positions in order to achieve high manufacturing accuracy. These positioning bolts here protrude from the molding tool surface and engage in openings introduced into the segments when the segments are introduced into the molding tool.

[0048] According to one embodiment, it is provided that the fiber composite component to be produced is a half shell of a rotor blade, in particular for a wind turbine, or a rotor blade, in particular for a wind turbine.

[0049] According to one embodiment, the sharp angle bevel Installed on the end of the segment facing the base section of the fiber composite component, in order to improve the attachment to the remaining fiber material of the fiber composite component, in particular to the inner layer. The sharp bevel can be introduced individually for each segment later or already during the production of the hybrid plate.

[0050] According to one embodiment, a flange is provided in the opening region of the section. The bolt connection supports the laminate in the thickness direction by means of the flange and thus suppresses failure-causing delamination, so that higher loads can be transmitted. However, for this purpose, a flat flange surface perpendicular to the hole axis is required. In order to avoid subsequent milling of the flange surface, circular recesses are provided in the base layer and the cover layer, so that the section forming the flange surface can be manufactured as a flat component with high precision. In order that the flange surface does not fill with resin during the injection of the fiber composite component, a flange is arranged there, which is removed again after the injection.

[0051] The inventive concept also includes a method for producing a fiber composite hollow component, comprising the following steps:

[0052] - producing a plurality of individual fiber composite shells, correspondingly according to the method of any one of the preceding claims,

[0053] - Joining two fiber composite half shells to form a fiber composite hollow component.

[0054] The fiber composite shells can be, for example, two fiber composite half shells or four fiber composite quarter shells, which are then assembled to form the fiber composite hollow component.

[0055] The inventive concept also includes a wind power plant having a plurality of rotor blades produced according to the above method. The rotor blade can be produced as a whole or from two or more half shells which are then joined to one another. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Figure 1 The manufacturing of a fiber-metal hybrid section, or section for short, is shown schematically. First, a fiber-metal hybrid plate 10 is manufactured from a fiber-metal hybrid material, such as in Figure 1 As can be seen on the left side of the figure. The mixed material consists of alternating fiber layers and metal layers, wherein it is not necessary to compulsorily follow a metal layer after each fiber layer or a fiber layer after each metal layer. Instead, it is conceivable that a plurality of fiber layers or metal layers are arranged in succession and the material is then changed.

[0064] As can be seen, according to the invention, the fiber-metal hybrid plate 10 is produced such that a bevel region 12 with a bevel adjoins the main region 11 , so that in this bevel region 12 the flat, unbendable plate 10 is inclined toward its underside.

[0065] After the fiber-metal hybrid plate 10 is produced, it is separated into a plurality of fiber-metal hybrid segments 20 by means of water jet cutting (or another method, such as sawing or laser cutting). Before or after the separation, openings 21 are produced in the segments 20 in the main regions 11 without sharp bevels, which openings are used in subsequent operation in accordance with the intended purpose to fasten the fiber composite component to be produced to a superordinate structure. The openings 21 can also be introduced by means of water jet cutting.

[0066] Figure 2 A detailed cross-sectional view of a section 20 is shown. The section 20 is divided here according to the regions of the previously produced hybrid plate 10, namely the main region 11 containing the transition region 11a and the sharp bevel region 12. The main region 11 contains fiber layers 30 and metal layers 32 arranged alternately in layers. In the main region 11 there is also an opening 21, which has a particularly high wall strength due to the metal layer 32.

[0067] It can be seen in the transition region 11a that the metal layer 32 can have different lengths in order to spatially distribute the stress overhangs within the component. These stress overhangs occur at material transition points, i.e., at those points where the metal layer ends and is continued by the fiber material layer. It is recommended to spatially separate the material transition points in order to avoid overlapping and thus aggravation of the individual stress overhangs.

[0068] When such a segment is produced from a hybrid plate, the hybrid plate is designed in such a way that individual fiber layers 30 are replaced by metal layers 32 , so that the fiber material 30 adjoins the ends of the metal layers 32 .

[0069] Figure 3 The diagram shows how the section 20 with its opening 21 is arranged in the connecting section of the fiber composite component to be produced, wherein Figure 3 In the illustration of , the remaining fiber material of the entire fiber composite component is not shown for the purpose of intuitive explanation. The sections are arranged in such a way that they follow the curvature of the component to be manufactured in the connecting section, so that the entire connecting section is ultimately manufactured from the fiber-metal hybrid material, so that the openings 21 required in the connecting section have high hole wall strength.

[0070] Figure 4 It is shown how the segments are now introduced into the shaping tool 40. On the left side, an exploded view is shown here, which shows the shaping tool 40 separated from the preform 50 with the segments, while on the right side, the introduced structure is shown.

[0071] In this case, positioning pegs 42 are provided in the surface 41 of the forming tool 40 , which engage in openings thereof when the individual segments are inserted and thus fix the respective segment in the position provided for this purpose.

[0072] The preform 50 thus produced in the molding tool 40 has an outer layer 51 formed from a fiber material of a fiber composite material and an inner layer 52 likewise formed from a fiber material of a fiber composite material. In this case, the fiber material of the outer layer 51 is first introduced into the molding tool, wherein the individual sections are then inserted into the molding tool. Subsequently, sections and parts of the outer layer 51 are again covered by the inner layer 52 made of fiber material.

[0073] Figure 5A detailed example of a positional fixation in a tool is shown. Here, a sleeve 60 with a flange 61 is first inserted into the opening 21. The sleeve 60 is conically shaped on the inner wall and tapers downwards so that a metal bolt 62 can be inserted, which is also conically shaped and corresponds to the inner wall of the sleeve 60. The metal bolt 62 has an opening into which a screw 63 or bolt can be inserted for fastening. Both the sleeve and the bolt are only used to position the segment during production and are subsequently removed again.

[0074] In order to avoid milling the flange surface later, circular notches are provided in the base layer and the cover layer, so that the flange surface can be formed in the section of the flat component with high precision. In order to prevent the flange surface from being filled with resin when injecting the fiber composite component, a flange 61 is arranged there, which is removed again after injection.

[0075] Figure 6 An embodiment is shown in which the segments have a trapezoidal cross section. Figure 6 2 shows three end faces 22 of segments 20 having a trapezoidal shape. Here, the segments are separated at an angle so that when adjacent elongated sides 23 abut against each other, adjacent segments have a curved surface.

[0076] The lower edge 24 of the end face 22 of the segment, which faces the outer layer, has a longer edge length than the upper edge 25 which faces the inner layer.
