Definitions
- the present invention relates to a process for the production of continuous fiber-reinforced molded parts from thermoplastics and a motor vehicle molding.
- a disadvantage of the prior art is that the pressing process due to necessary material supernatants has an increased material waste result. Furthermore, the 3D structure which arises only during the pressing process, and the associated forced orientation of the continuous fibers during the forming process, merely represents a compromise between the fiber orientation in the third dimension and the necessary flow paths of the material.
- a further disadvantage is that in order to achieve high degrees of deformation increased demand for flowable material, ie is necessary to thermoplastic matrix, which inevitably leads to an increased component weight. In addition, very high degrees of deformation can not be realized because otherwise fiber breaks occur within the continuous-fiber-reinforced molded part.
- the object underlying the present invention is to provide a process for the production of continuous fiber-reinforced molded parts from thermoplastic materials, which overcomes the disadvantages of the prior art.
- the present invention it is advantageously achieved by preforming the unidirectional fiber-reinforced mats into a three-dimensional preform such that in the subsequent consolidation step, the molding substantially does not have to undergo forming or flow processes. Therefore, advantageously less flowable material, ie less thermoplastic matrix is required, as is the case in the prior art. Due to the possibility of fiber orientation according to the invention in the third dimension is also achieved that the forces acting on the molded part produced by the molding according to the invention, and the resulting within the molding load paths can be optimally absorbed by the unidirectional fiber reinforcement.
- the unidirectional fiber reinforced mats are preferably cut from unidirectional films. Compared to the prior art, which discloses only band-shaped structures, the post-processing and the resulting material section can be reduced to a minimum by the targeted cutting of the mats.
- the fiber reinforcement of the mats is preferably formed by mineral fibers, in particular glass fibers, and / or carbon fibers, and / or aramid fibers, and / or polymeric fibers, and / or synthetic fibers and / or from fibers of renewable raw materials. It may be advantageous to perform the fixing of the position of the mats to each other by means of a welding process. Preferably, the position fixing of the mats takes place by an ultrasonic and / or heating element and / or laser welding process. The positional fixing of the blanks of the mats to one another during or after completion of the construction of the preform has the advantage that the preform has a significantly improved handleability.
- the mats are at least partially preheated prior to depositing on the workpiece carrier with the aim of increasing the flexibility of the mats. Due to the increased flexibility of the mats is advantageously achieved that they can adapt better when placed on the workpiece carrier of the three-dimensional rough contour. It is preferably provided to heat the workpiece carrier in order to be able to maintain the flexibility of the mats.
- the heating of the preform or the preheating of the mats is preferably carried out by convection heating and / or infrared radiation. Further preferably within a convection and / or infrared continuous furnace. The heating by infrared radiation or by convection heating represents for a component which already has a dreidimensionale coarse contour, an optimal method for uniform heating of the entire preform.
- a robot system For the transfer of the mats and / or for the introduction of the preform, a robot system can be used.
- a tetrapod system for example a so-called FlexPicker TM from ABB
- an alternative software-based camera monitoring and control unit image recognition
- the use of rotober systems achieves a favorable reduction in the duration of the process compared to a manual process.
- a high reproducibility of the method can be achieved through the use of robots. This is particularly advantageous with regard to a reproducible alignment of the mats to each other, and the associated fiber orientation within the molding.
- the setting of the homogeneous inner mold pressure is preferably carried out by an edge-side injection molding of a circumferential plastic welt in the injection molding process within the mold.
- the adjustment of the homogeneous inner mold pressure can also be done by additional insertion of GMT pieces (glass mat reinforced thermoplastic), more preferably by a shot-pot technique or by inserting sealing cords in the mold or by inserting a sealing film in the mold.
- GMT pieces glass mat reinforced thermoplastic
- the abovementioned possibilities can be used in any combination.
- a uniform consolidation of the preform or of the molded part is achieved by the homogeneous inner mold pressure.
- the edge region is also closed in an advantageous manner, so that no fiber material can escape from the edge region or there is no splicing of the fiber material used. Due to the edge gating only little additional material is needed, which in particular does not significantly increase the weight of the molding.
- complementary functions such as clips, recordings or attachment points can be formed.
- the workpiece carrier is moved on a conveying path, whereby the individual process steps take place along this conveying path.
- the workpiece carrier can thus be moved along a plurality of stations, in particular a plurality of robot stations, in order to further minimize the process time until the completion of the molding.
- the molding is preferably produced within a time interval of 20 to 120 seconds, more preferably within a time interval of 40 to 90 seconds, and even more preferably within a time interval of 55 to 65 seconds.
- the specified time intervals represent normal production times for molded parts of the automotive industry, so that the inventive method can also be integrated within the production line of a motor vehicle.
- part of the invention is a motor vehicle molding, wherein the molding is three-dimensionally constructed of at least two unidirectional fiber-reinforced mats in a manner such that the fiber orientation is matched to the attacking in the later use of the molding forces and thereby resulting within the molding load paths.
- the motor vehicle molding on a plastic piping.
- the Kunststoffke- is preferably integrally formed peripherally on the molding.
- the molding of the plastic bead on the motor vehicle molding by an injection molding process within an injection molding or injection molding process.
- the plastic piping is formed from a fiber-reinforced, more preferably short-fiber-reinforced plastic.
- the peripheral edge of the plastic piping preferably forms a closed structure. Particularly advantageous thus increases the structural rigidity of the molding.
- the molded part has a cavity with at least one closed cross section.
- the at least one closed cross section can in particular be produced by an expansion body arranged within the preform.
- the expansion body is pressurized by means of a fluid so that it forms the cavity within the motor vehicle molding in conjunction with the walls of the molding tool.
- an elastic bladder in particular a silicone bladder, is used as the expansion body. It is also conceivable to work with a lost core, which forms the cavity within the molding. Further alternatives are gas and / or water injection methods.
- the fiber reinforcement of the mats or of the molded part prefferably be formed by mineral fibers, in particular glass fibers and / or carbon fibers and / or arabin fibers and / or polymeric fibers and / or synthetic fibers and / or from fibers of renewable raw materials is or are.
- the motor vehicle molding is designed as a supporting structure of an opening of the vehicle closing flap or door, or as a structural part of the body. Further preferably, the molded part may be formed as part of the underbody of the vehicle or as a battery case or as a battery carrier. Furthermore, in the context of the invention is that the molding is used in an aircraft as a structural profile.
