[0006] Method and manufacturing system for arranging thermoplastic UD tapes for the production of a component made of fiber-reinforced plastic

[0007] The invention relates to a method and a manufacturing system for arranging thermoplastic UD tapes for the production of a component made of fiber-reinforced plastic.

[0008] Methods for manufacturing fiber-reinforced plastic components using thermoplastic UD tapes are generally known. One method involves laying the UD tapes onto a flat or curved surface. Another method involves winding the UD tapes. The UD tapes are typically positioned using pressure and temperature. The UD tapes can be heated, for example, in a gusset area or even pre-heated. For pressure application, the manufacturing systems often include a compression roller that presses the pre-heated UD tapes onto a substrate, thereby consolidating them. Consolidation is particularly important when the UD tape is laid on top of a previously laid UD tape to create a strong bond.

[0009] The UD tapes are first heated, then laid down or wound, and subsequently pressed onto a substrate using a compression roller, resulting in in-situ consolidation. The UD tapes are typically arranged in multiple layers, each layer being heated and compacted. This process creates a layered, fiber-reinforced component.

[0010] US 2017 / 0080646 A1 , DE 10 2014 218 978 A1 , DE 10 2013 224 835 A1 , DE 20 2009 014 155 U1 , DE 102006 060 361 A1 , WO 2019 / 123209 A1 and EP 3 141 378 A2 disclose fiber laying heads and other devices for processing fibers.

[0011] One disadvantage of fiber-reinforced components manufactured in this way is that residual stresses arise in the material, limiting the achievable crystallinity. These residual stresses and the low crystallinity lead to adverse mechanical properties. Furthermore, the consolidation of the tape layers may be inadequate with regard to bond strength.

[0012] One approach to reducing these disadvantages is to place the UD tapes on a heated table, a pre-formed tray, or a winding core. During winding, it is possible to heat the interior. However, these approaches do not lead to satisfactory results, or only achieve limited results, especially with high demands on the component being manufactured, complex geometries, or large components. Temperature control options are particularly limited with thicker components.

[0013] It is therefore an object of the invention to provide a method and a manufacturing system for arranging thermoplastic UD tapes for the production of a fiber-reinforced plastic component, which reduces or eliminates one or more of the aforementioned disadvantages. In particular, it is an object of the invention to provide a solution that enables the production of fiber-reinforced plastic components with improved material properties.

[0014] This problem is solved by a method and a manufacturing system according to the features of the independent claims. Further advantageous embodiments of these aspects are specified in the respective dependent claims. The features disclosed in the claims, the description, and the drawings can be combined individually, in any technologically meaningful way, and further embodiments of the invention are shown.

[0015] According to a first aspect, the aforementioned problem is solved by a method for arranging thermoplastic UD tapes for the production of a component made of fiber-reinforced plastic, comprising the steps of: arranging at least one thermoplastic UD tape by means of pressure and / or temperature application, wherein the at least one arranged UD tape forms a laminate surface, measuring a surface temperature of the laminate surface at a plurality of measuring positions, and tempering the laminate surface at a plurality of tempering zones based on the measured surface temperature, so that a position-dependent tempering of the laminate surface is effected in order to set a predefined temperature distribution with target temperatures on the laminate surface.

[0016] The invention is based on the understanding that laying UD tapes by prior heating and subsequent pressing onto a substrate is insufficient for many technical applications to meet the high mechanical requirements of these applications. The invention is further based on the understanding that previous approaches are inadequate, particularly for large-area and large-volume components. Since the process has thus far been considered essentially locally within the processing zone, no approaches existed for improving the material properties of large-area and large-volume components.

[0017] The inventors further discovered that undesirable cooling processes occur in large-area and large-volume components, which depend, among other things, on the manufacturing sequence and / or web strategy. Cooling occurs uncontrolled through heat conduction into the surrounding material and through heat conduction, convection, and thermal radiation to the surrounding air. This is primarily due to the fact that at a specific location on the large-area and large-volume component, a further application of heated tape or a heated tape section only occurs at long intervals. For example, in a large-area aircraft fuselage section, a single position on the laminate surface is only covered with another heated UD tape at intervals of several minutes.

[0018] For small components, this time can be as little as seconds.

[0019] Based on these findings, the inventors have now provided for the component surface to be tempered during manufacturing, i.e., during the laying or winding of the UD tapes. For this purpose, a target temperature on the surface and, if necessary, a temperature gradient within the laminate, which can be position-dependent and variable over time, are first defined. The surface temperature is then measured, and subsequently, the surface is tempered in such a way that the surface temperature and / or the temperature gradient correspond to the specified target temperature and / or the temperature profile. As a result, optimal consolidation of the stacked UD tapes can be achieved, the crystallinity of the component is improved, and residual stresses within the component are reduced.In general, the method can be used to ensure steady-state process conditions or to deliberately introduce local temperature differences in order to compensate for disturbances resulting from, among other things, material inhomogeneities or a changing component geometry.

[0020] The process is designed for applying thermoplastic UD tapes. UD tapes are also known as unidirectional tapes or unidirectional fiber-reinforced tapes. A UD tape comprises a thermoplastic matrix in which reinforcing fibers are embedded. The matrix is ​​a thermoplastic matrix made of a thermoplastic polymer. The reinforcing fibers can be, for example, glass, carbon, or natural fibers. The fibers are typically continuous strands.

[0021] The thermoplastic UD tapes are arranged by applying pressure and / or temperature. This arrangement can involve winding and / or laying. The UD tapes can be placed on a permanent substrate, such as a liner, or on a temporary substrate, such as a heating table. The substrate can also be temperature-controlled. The component can consist of or comprise one, two, or multiple UD tapes. The process inherently creates a surface on the partially or fully manufactured component, which in this context is referred to as the laminate surface. The arranged, particularly laid and / or wound, UD tapes are referred to as the laminate.

[0022] During the manufacturing process, the laminate surface is regularly covered with another layer of UD tape or a section of UD tape, so that the applied UD tape forms the laminate surface at that position. When the final layer of UD tape is applied to the component, the laminate surface corresponds to the surface of the finished component. The thermoplastic UD tapes are arranged in such a way that they consolidate with a substrate, for example, a previously applied UD tape or a section of UD tape.

[0023] The method further comprises the step of measuring the surface temperature of the laminate surface at a plurality of measuring positions. The surface temperature is measured on the already laid or wound UD tape, and in particular not before the UD tape has been applied. The surface temperature is measured over a large area. It is preferred that the plurality of measuring positions is formed by a measuring field, thereby preferably enabling spatially resolved temperature measurement. A plurality of measuring positions means, in particular, one, two, or more measuring positions.

[0024] It is preferred that the surface temperature be measured across the entire surface and / or over a large area. For example, the surface temperature can be measured with a thermal imaging camera so that the surface temperature can be determined along the entire laminate surface. Furthermore, it is preferred that the surface temperature be measured at more than 10, more than 50, more than 100, or more than 500 measurement positions. The resolution of the measurement result can be continuous or discrete. For example, the resolution can be in the millimeter or centimeter range.

[0025] The laminate surface is tempered at multiple temperature control zones based on the measured surface temperature. Tempering based on the measured surface temperature means, in particular, that a tempering intensity is derived from the measured surface temperature, and the laminate surface is tempered accordingly, for example, heated. For instance, a surface temperature of 145°C might be measured at a first measurement point, with a target temperature of 160°C. The laminate surface would then be tempered such that the temperature at this point rises from 145°C to 160°C. The target temperature can be defined as a function of time, making it variable over time. Multiple temperature control zones specifically refer to one, two, or more temperature control zones.

[0026] The fact that the laminate surface is tempered at a multitude of temperature control zones means, in particular, that the laminate surface is tempered at two or more sections of the component or the component to be manufactured. The temperature control zones can, for example, have a size between one square millimeter and 500 square centimeters. The surface area of ​​the component can be several square meters. Tempering the laminate surface generally also tempers the laminate itself, especially the material beneath the laminate surface. This tempering preferably creates a predefined temperature distribution, particularly a temperature gradient, within the laminate.

[0027] The laminate surface is tempered by establishing a predefined temperature distribution across the surface. This temperature distribution defines target temperatures along the laminate surface. These target temperatures can be the same or vary depending on the location. For example, the target temperatures in an end-face region of a tank can differ from the target temperatures in a cylindrical section of the tank. Furthermore, it may be preferable to temper the laminate surface in such a way that the position-dependent tempering is achieved over time.

[0028] A preferred embodiment of the method comprises the following steps: comparing the measured surface temperatures with target temperatures defined for the measurement positions, and tempering the laminate surface, particularly at the measurement positions, such that the surface temperature, especially at the measurement positions, corresponds to the respective target temperature. The measurement positions and the tempering zones are located on the laminate surface. Each measurement position can thus be assigned to a tempering zone. In other words, each measurement position is located within a tempering zone for which a target temperature applies, so that a target temperature is also defined for each measurement position. If a surface temperature at a measurement position differs from the target temperature, the laminate surface at that measurement position can be tempered so that the surface temperature corresponds to the target temperature.

[0029] It may be preferable to determine a temperature difference value (AT) during the comparison. Based on the AT, a temperature control parameter is preferably determined, for example, a heat output or a laser output. Furthermore, the duration of the temperature control process can also be a temperature control parameter.

[0030] The surface temperature of the laminate surface is preferably measured without contact in order to avoid any influence on the component quality through the temperature measurement, e.g. with a thermal camera, a pyrometer, in particular a pyrometer array.

[0031] The tempering of the laminate surface is preferably carried out in such a way that the temperature is slightly below the crystallization temperature of the UD tape.

[0032] Furthermore, it may be preferable to cool the laminate surface, particularly with a fluid flow, for example an air flow.

[0033] That the surface temperature corresponds to the target temperature can, in particular, mean that there is a deviation of less than 20%, less than 10%, or less than 5% of the target temperature between them.

[0034] In a further preferred embodiment, the method includes the steps of: a second measurement of the surface temperature during tempering and controlling and / or regulating the tempering based on at least one measurement result from the second measurement.

[0035] The initial surface temperature measurement is essentially independent of the arrangement of the UD tapes and independent of any heat input. The second measurement is then taken during the tempering process, allowing the relationship between the measured surface temperature and the target temperature to be observed. Consequently, a tempering parameter can be controlled and / or regulated to advantageously achieve the target temperature.

[0036] In another preferred embodiment of the method, the tempering process includes or is the application of heat radiation to the laminate surface.

[0037] It is preferred that the heat radiation is provided by one or more emitters, in particular an infrared emitter or laser. It is further preferred that the heat emitter is moved along, preferably spaced apart, the laminate surface. Alternatively or additionally, it is preferred that the laminate surface is moved relative to the heat emitter, in particular rotationally and / or translationally.

[0038] In a further preferred embodiment, the tempering process includes or comprises the application of a high-energy beam, in particular a laser beam, to the laminate surface. It is particularly preferred that the high-energy beam is moved along the laminate surface. It is further preferred that the laminate surface is moved rotationally and / or translationally during the application of the high-energy beam.

[0039] Furthermore, it may be preferred that the high-energy beam is divided into several partial beams, thereby enabling multiple temperature control zones on the laminate surface to be controlled with a single high-energy beam. It may also be preferred that two or more high-energy beams are used.

[0040] Another preferred embodiment is characterized by contactless surface temperature measurement. It is further preferred that a thermal image is generated during the surface temperature measurement. This thermal image can be generated, for example, using a thermal imaging camera. A thermal image offers the particular advantage of providing a measurement value for a large number of measurement positions, which can then be used to control the temperature at those positions.

[0041] In a further preferred embodiment of the method, the component has at least one axis, in particular a rotational axis, comprising the steps of: rotating the component about the axis and moving a temperature control device along the axis to temperature the laminate surface at desired positions. The temperature control device is specifically designed for temperature control of the laminate surface. For example, the device can be configured to emit a high-energy beam or thermal radiation. The temperature control device can also preferably be the high-energy beam, in particular a laser beam, and / or the thermal radiation.

[0042] In another preferred embodiment of the method, it is provided that it includes the step: second tempering of a laminate backing, so that the laminate surface and the laminate backing are tempered to set the predefined temperature distribution.

[0043] The second tempering step can be achieved, for example, using a heated surface. This surface could be, for instance, a drying table, a drying tray, or a winding core, such as a liner.

[0044] According to a further aspect, the aforementioned problem is solved by a manufacturing system for arranging thermoplastic UD tapes for the production of a component made of fiber-reinforced plastic, comprising an arranging device which is arranged and configured to arrange at least one UD tape by means of pressure and / or temperature application, wherein the at least one arranged UD tape forms a laminate surface, a measuring device which is arranged and configured to measure a surface temperature of the laminate surface at a plurality of measuring positions, and a temperature control device which is arranged and configured to temperature the laminate surface at a plurality of temperature control zones based on the measured surface temperature, so that position-dependent temperature control, in particular heating and / or cooling, of the laminate surface is effected.to set a predefined temperature distribution with target temperatures on the laminate surface.

[0045] It is preferred that the temperature control device is linked to the measuring device via data transmission. This can be a direct data connection. Alternatively or additionally, the linkage can also be indirect, for example via a separate intermediate storage device, such as a server.

[0046] The data connection is designed in such a way that the measured surface temperatures can be processed so that the temperature control device can temper the laminate surface accordingly.

[0047] In a preferred embodiment of the manufacturing system, it is further provided that the temperature control device has a beam unit for emitting a high-energy beam, in particular a laser unit.

[0048] The beam unit can have two or more beam sources. The beam unit can include a beam guide and / or at least one beam optic. Furthermore, the beam unit can include or consist of direct diodes, in particular a VCSEL and / or a direct diode laser. The laser unit is preferably configured to emit a laser beam in the near-infrared and / or infrared wavelength range. The laser unit can be a diode laser and / or a fiber laser.

[0049] In a further preferred embodiment of the manufacturing system, the temperature control device comprises a mirror element, in particular a polygonal mirror element, which is arranged and configured to direct the high-energy beam, in particular a laser beam, onto the temperature control areas of the laminate surface. The mirror element is particularly advantageous for winding. A polygonal mirror element has the advantage that the high-energy beam is split and can be directed simultaneously onto several temperature control areas. Furthermore, rotation through the component and translation through the polygonal mirror element can advantageously be provided. The mirror element can also be, or include, a 3D scanner.

[0050] In a further preferred embodiment of the manufacturing system, the temperature control device comprises two or more mirror units, in particular laser scanners, which are arranged and configured to direct the high-energy beam, in particular a laser beam, onto the temperature control areas of the laminate surface.

[0051] In a further preferred embodiment, it is provided that the two or more mirror units are arranged and / or can be arranged depending on a surface geometry, and preferably the two or more mirror units are arranged to be movable translationally or rotationally.

[0052] Especially with components that have curved surfaces, an individual arrangement of the two or more mirror units can be advantageous in order to ensure steady-state process conditions or to introduce local temperature differences in a targeted manner.

[0053] Another preferred embodiment of the manufacturing system is characterized in that the temperature control device comprises an infrared emitter and / or a direct laser system, for example a VCSEL or a diode bar, which is arranged and configured to be movable at least along an extent of the laminate surface, in particular along a component axis.

[0054] The infrared emitter is positioned at a distance from the laminate surface and can be moved along it. An infrared emitter that can be moved along the laminate surface offers the advantage of a simple manufacturing system setup. In particular, no laser safety measures are required.

[0055] In a further preferred embodiment of the manufacturing system, the measuring device is or comprises a thermal camera and / or a pyrometer. In particular, two or more pyrometers can be provided as a pyrometer arrangement, also referred to as a pyrometer array.

[0056] In a further preferred embodiment of the manufacturing system, the assembly includes a compression element, in particular a compression roller, and a heating unit for consolidating the UD tape. The compression element and the heating unit are typically arranged in a tape laying head. In a further preferred embodiment of the manufacturing system, it includes a control device coupled to the measuring device and temperature control device, which is configured to control the temperature control device such that the predefined temperature distribution with target temperatures is established on the laminate surface.

[0057] The coupling of the control device with the measuring device and the temperature control device is designed, in particular, for data transmission. This coupling can optionally be indirect, for example via a server. The control function can also include or encompass regulation.

[0058] It is preferred that the measuring device generates and preferably provides measurement data representing the surface temperature of the laminate surface at a plurality of measuring positions. It is further preferred that the control device is configured to receive the measurement data and / or generate temperature control parameters based on the measurement data, wherein the temperature control parameters are parameterized such that, after temperature control, the surface temperature of the laminate surface corresponds to the target temperature when the temperature control device is operated with these parameters. The temperature control device is particularly arranged and configured to receive the temperature control parameters from the control device.

[0059] The control device is preferably configured to generate the temperature control parameters based, among other things, on component parameters. For example, a higher temperature control power may be required for a greater component thickness.

[0060] In a further preferred embodiment, the control device is configured to compare the measured surface temperatures with target temperatures defined for the measuring positions and to generate temperature control parameters such that the laminate surface at the measuring position is tempered to the target temperature.

[0061] The target temperature can be defined as variable depending on the temperature control range and / or over time. The specific characteristics of the temperature profile generally depend on the component, as, for example, the first layer exhibits different thermal behavior than the tenth layer.

[0062] Furthermore, it may be preferred that the control device is configured to control and / or regulate the temperature control based on at least one measurement result from a second measurement, wherein the second measurement takes place during the temperature control process.

[0067] It is further preferred that tempering takes place before, during, and / or after the application of the UD tape in order to control the laminate temperature, particularly the surface temperature. Position-dependent and / or time-dependent tempering is also preferred. Furthermore, it may be preferred that the tempering device is deactivated or deactivatable, particularly to avoid tempering the assembly device and, in particular, to prevent it from being subjected to a high-energy beam.

[0087] The exemplary embodiments described below are preferred embodiments of the invention. In these exemplary embodiments, the described components each represent individual features of the invention, which can be considered independently of one another. Each of these features further develops the invention independently and can be considered part of the invention individually or in a combination other than that shown. Furthermore, the described embodiments can also be supplemented by other features of the invention already described.

[0088] Figure 1 shows a manufacturing system 100 for applying thermoplastic UD tapes 102 to produce a component 104. The component 104 is rotated about its component axis 106 in a rotational direction 110. During the rotational movement, the UD tape 102 is applied to the component 104. The component 104 can be, for example, a pressure tank, with or without a liner.

[0089] The UD tape 102 is applied to the component 104 by means of an arrangement device 112. For this purpose, the arrangement device 112 has a feed mechanism for the UD tape 102, which is not shown in detail but is known to those skilled in the art. Before the UD tape 102 is applied, it is heated by the heating unit 116, for example in a gusset area, and pressed onto the substrate surface of the component 104 being manufactured by the compression element 114, which is designed here in a roller shape. Each applied UD tape 102 forms a laminate surface 108, at least temporarily. The manufacturing system 100 also includes the measuring device 118 and the temperature control device 120. The measuring device 118 is designed to measure the surface temperature of the laminate surface 108 at a plurality of measuring positions.

[0090] The temperature control device 120 is designed to temperature-control the laminate surface 108 at a multitude of temperature control zones based on the measured surface temperature. This temperature control is carried out in such a way that position-dependent temperature control of the laminate surface 108 is achieved. The temperature control device 120 emits a temperature control medium 122, for example a high-energy beam or thermal radiation, to temperature-control the laminate surface 108.

[0091] The manufacturing system 100 further comprises the control device 152. The control device 152 is configured to control the temperature control device 120 in such a way that the predefined temperature distribution with target temperatures is set on the laminate surface 108.

[0092] Figure 2 shows the manufacturing system 100 shown in Figure 1 from a further perspective. In particular, the spatially resolved temperature measurement system with a measuring field 125, which has measuring positions 124, and three temperature control zones 126, 128, 130 are shown. Each temperature control zone 126, 128, 130 is schematically represented as containing one measuring position 124, 124', 124". In the implementation, a multitude, for example more than 100 or more than 1,000 measuring positions 124, are distributed across the laminate surface 108, for example, configured as the measuring field 125. Furthermore, the measuring positions 124 can also be considered as overlapping areas from which, for example, a thermal image is generated. Likewise, a multitude of temperature control zones 126, 128, 130 can also be defined.

[0093] Figure 3 shows that the temperature control device 120 has a polygon mirror 132 which is arranged and designed to split a laser beam 134 and align it to the temperature control areas 126, 128, 130 of the laminate surface 108.

[0094] Figure 4 shows that the temperature control device 120 comprises four mirror units 140-146, which are arranged and configured to direct the laser beam 134 onto the temperature control areas 126, 128, 130. The mirror units 140-146 are adapted to the surface geometry of the component 104.

[0095] Figure 5 also shows a setup with mirror units 140-146, which, however, are not essentially adapted to the geometry of component 104.

[0096] Figure 6 shows a temperature control device 120 with a translationally movable infrared emitter 148. The infrared emitter 148 can be moved translationally in the direction of movement 150. The additional rotational movement 110 of the component 104 advantageously allows the laminate surface 108 to be tempered.

[0097] Figure 7 shows the application of a UD tape 102, where the component 104 is non-rotationally symmetric. This is a deposition process. The component 104 shown in Figure 7 could, for example, be part of an aircraft fuselage and have large dimensions.

[0098] Figure 8 also shows a deposition process for the UD tape 102, with component 104 shown schematically. Furthermore, Figure 8 shows a second temperature control device 154, which is arranged and configured to temperature control the back side of the laminate 104 facing away from the laminate surface 108.

[0099] Figure 9 schematically shows a method for arranging thermoplastic UD tapes 102 for the production of the component 104 made of fiber-reinforced plastic. The method comprises step 200: arranging at least one thermoplastic UD tape 102 by applying pressure and / or temperature, wherein the at least one arranged UD tape 102 forms a laminate surface 108.

[0100] In step 202, the surface temperature of the laminate surface 108 is measured at a multitude of measuring positions 124. In step 204, the laminate surface 108 is tempered at a multitude of temperature control zones 126, 128, 130 based on the measured surface temperature to establish a predefined temperature distribution with target temperatures on the laminate surface 108, thus achieving position-dependent temperature control of the laminate surface 108. The method and the corresponding manufacturing system 100 described above for in-situ temperature control of the laminate surface 108 enable the production of a higher-quality component 104 that exhibits lower residual stresses and increased crystallinity. Furthermore, the method and the corresponding manufacturing system 100 can be implemented with relatively simple means, thereby improving the applicability of the method.
