Definitions
- the invention relates to a method for producing a fiber-reinforced plastic hollow profile.
- Fiber-reinforced plastic profiles are becoming increasingly important in practice. This is particularly related to the fact that the weight of components which are used for example in the automotive or aircraft industry, plays a very important role against the background of the required reduction of C0 2 emissions.
- Plastic profiles are distinguished from metal components, for example made of steel, by a much lower weight. To ensure a comparable mechanical strength of these plastic components, the plastic profiles are often provided with a fiber reinforcement.
- DE 107 47 021 B4 discloses a method for injection molding endlessly fiber-reinforced hollow bodies.
- tubular braids are positioned and fixed in an injection mold, so that the braids are flowed through from the inside of the plastic melt in the injection mold during injection of the plastic melt.
- Another known manufacturing method for fiber-reinforced plastic profiles in a thermoplastic matrix is pultrusion. In this case, adjacent reinforcing fibers are pulled through a Pultrusionsdüse and soaked with synthetic resin.
- a disadvantage of this method is that only one fiber orientation can be realized in the profile longitudinal direction.
- the manufacturing process is started with the extrusion of a thermoplastic pipe.
- This pipe is unidirectionally reinforced as it is withdrawn from the extruder nozzle by drawing in a longitudinal roving.
- the extruded tube is used as a winding core, fiber layers with a targeted fiber orientation being applied to the tube in a winding station.
- the dry-wound tube is drawn into a heating area and radially expanded there in the heated state by an expanding mandrel. In this area, the actual impregnation and compaction of the layers takes place. This process is very complex.
- injection molding special processes in which the assembly injection molding is combined with the fluid injection technique by injection molding.
- preheated tissue by-products are preformed by the melt pressure and further deformed in the same cycle by means of fluid injection technique and finally consolidated by the heat dissipation.
- the invention has for its object to provide a method which allows the fast and cost-effective production of a mechanically highly resilient, fiber-reinforced plastic hollow profile.
- the object is achieved according to the invention by a method for blow-molding a fiber-reinforced plastic hollow profile
- this plastic tube is introduced into a reinforcing fibers containing reinforcing tube, wherein, as part of a blow molding process, the plastic hose is inflated and thereby pressed against the inner surface of the reinforcing hose; and during the blow molding process, the plastic and reinforcing hose are pressed together against the inner wall of a blow molding tool, thereby forming the fiber reinforced plastic hollow profile ,
- an intimate connection between the inner plastic hose and the surrounding reinforcing hose can be produced in a very simple manner by means of a blow molding process. Due to the internal pressure present in the plastic tube in the blow molding process, material of the plastic tube, which is still in the melt state, penetrates into the tissue structure of the reinforcing tube, so that an intimate connection of the two tubes arises. In the context of the invention, of course, this is also true that the reinforcing tube is completely penetrated by material of the plastic tube. The blowing process not only brings about the shaping of the finished component but at the same time brings about a consolidation of the plastic tube still in the melt state and the reinforcing tube. Overall, the method according to the invention thus permits the production of a mechanically highly loadable and nevertheless very light profile in a quick and thus cost-effective manner.
- a reinforcing hose a hose or a
- the reinforcing tube may contain mineral (in particular glass) and / or carbon and / or aramid fibers, in particular in endless form.
- the tubular braid or the tubular fabric is made of, in particular endless, mineral (especially glass) and / or carbon and / or aramid fibers.
- the reinforcing tube may for example be constructed of unidirectionally aligned in the tube axis direction, preferably endless, reinforcing fibers, which are held together by transversely arranged, preferably elastomeric bands.
- the reinforcing tube advantageously has a pronounced flexibility during the blow-molding process, so that the reinforcing tube can adapt very precisely to the shape of the blow-molding tool.
- the reinforcing fibers are interwoven and intertwined several times along the circumference of the reinforcing tube, so that the individual endless reinforcing fibers extend helically.
- a sustainable reinforcement of the fiber-reinforced plastic hollow profile is ensured transversely to the profile longitudinal direction, so that in particular a high torsional stiffness is present.
- the reinforcing tube may additionally contain, in particular endless, plastic fibers. These plastic fibers expediently melt at least partially during the blow-molding process and the concomitant consolidation of reinforcing tube and plastic tube, thereby facilitating this consolidation.
- polypropylene PP
- polyamide PA
- polyetherimide PEI
- polyphenylene sulfide PPS
- polyetheretherketone PEEK
- the plastic tube consists of one of the aforementioned polymers or a mixture of at least two of the aforementioned polymers.
- the blow molding process according to the invention is carried out at a blow molding pressure of 2 to 100 bar, preferably 5 to 50 bar, particularly preferably 10 to 30 bar.
- the pressure is thus much lower than is usual, for example, in an injection molding process.
- a high-pressure blowing process e.g. at a pressure of 100 to 500 bar, preferably 200 to 400 bar.
- the reinforcing tube before the blow molding process is additionally surrounded by an outer plastic tube, which is pressed against the inner wall of the blow molding tool during the blow molding together with the plastic and the reinforcing tube.
- this outer plastic tube is produced via an extrusion process.
- the three-layer composite produced by this method allows in a simple manner a complete embedding of the reinforcing tube in a matrix formed by plastic tube and outer plastic tube.
- materials for the outer plastic tube the materials already mentioned with respect to the plastic tube can be used.
- plastic hose and outer plastic hose can be made of the same material.
- the components produced by the method according to the invention can be used in a variety of ways.
- the fiber-reinforced plastic hollow profile can be designed in particular as a component for crash management systems (CMS) in motor vehicles, as a load-bearing component of a motor vehicle body system or generally as a motor vehicle structural component.

- the fiber-reinforced plastic hollow profile produced by the method according to the invention may be formed as an aircraft structural component.

- Fig. 2 shows an alternative inventive manufacturing method
- Fig. 3 is a fragmentary view of a reinforcing tube used in a manufacturing method according to the invention.
- 1 shows a method for blow molding a fiber-reinforced plastic hollow profile 1.
- a thermoplastic plastic tube 2 is first produced by means of an extrusion process.
- This hose 2 can be produced continuously or discontinuously and is in a hot, moldable state due to the subsequent blow molding process.
- the designated also as a preform plastic hose 2 is usually made in a flanged tool 3 and ejected down.
- the material thickness in the tube 2 is regulated according to the shape of the finished plastic hollow section 1.
- this plastic tube 2 is introduced into a reinforcing tube 5 containing reinforcing fibers 4.
- a mandrel enters the plastic tube 2 from above or below.
- two-part blow mold 6 moves to and covers the two hoses 2,5 together with the mandrel.
- the plastic tube 2 is inflated and thereby pressed against the inner surface of the reinforcing tube 5.
- compressed air see the arrow in the middle illustration of FIG. 1 is pressed into the plastic tube 2 by the mandrel and thereby the plastic and reinforcing tubes 2, 5 together against the inner wall of the blow mold 6 pressed, whereby the shaping of the fiber-reinforced plastic hollow profile 1 takes place.
- the plastic tube 2 is cooled.
- the plastic thus adapts to the predetermined shape and becomes firm, the melt of the plastic tube 2 at least partially penetrating or even penetrating the open structure of the reinforcing tube 5 due to the internal pressure, thus bringing about a consolidation of plastic tube 2 and reinforcing tube 5.
- the device shown in FIG. 1 for carrying out the method according to the invention has a fixing device, not shown, for fixing the reinforcing tube 5 during the introduction of the plastic tube 2 and the subsequent blow molding process.
- a fixing device for fixing the reinforcing tube 5 during the introduction of the plastic tube 2 and the subsequent blow molding process.
- the blow molding method according to the invention has the advantage over injection molding that hollow parts can be produced in a simple manner and also undercuts without a slide can be produced to a limited extent.
- a variation of the wall thickness is directly compared to the injection molding in the blow molding process possible.
- the reinforcing tube 5 which has a hybrid character, that is, for example, contains endless glass and carbon fibers 4. It is also within the scope of the invention that, as shown in FIG. 3, the reinforcing tube 5 is constructed of reinforcing fibers 4 aligned unidirectionally in the tube axis direction x, which are held together by elastomeric bands 7 arranged transversely thereto. Alternatively, an intimate interweaving or interlacing of the endless reinforcing fibers according to FIGS. 1 and 2 ensures in particular a high torsional rigidity of the finished plastic hollow profile 1.
- the reinforcing tube 5 In addition to the glass and carbon fibers 4, the reinforcing tube 5 according to FIG Plastic fibers 4 '. These plastic fibers 4 'melt at least partially during the blow molding process due to the pressed, hot melt of the plastic hose 2 and thereby facilitate the consolidation of reinforcing hose 2 and plastic hose 5.
- the plastic hose shown in FIG. 1 consists of PP, PA, PEI, PPS or PEEK, or else a mixture of at least two of these polymers.
- the blow molding process is carried out at a pressure of 5 to 50 bar, preferably 10 to 30 bar.
- the reinforcing tube 2 before the blow molding process is additionally surrounded by an outer plastic tube 8 produced by means of a further extrusion tool 3 'which, during the blow molding process, cooperates with the plastic and reinforcing tubes 2, 5 the inner wall of the blow mold tool 6 is pressed.
