Definitions
- the present invention relates to a mat which has fibers made of different materials and to a thermally deformable composite body produced from this mat. It further relates to a method for producing such a mat, a method for producing such a composite body and a method for producing a component from such a composite body.
- Composite bodies in particular made of a fiber-reinforced plastic, are used for the longer to replace materials such as wood and metal.
- Parts of road vehicles in which, for example, parts of the seats, dashboards, parts of the bumpers, etc. are made from fiber-reinforced thermoplastic materials can be mentioned as a non-exhaustive example. Specifically, for example, glass fiber reinforced polypropylene.
- the glass fibers should be soaked with polypropylene, for example, so that every single fiber is completely covered by the thermoplastic material, so that the glass fibers are firmly embedded in the polypropylene and the polypropylene is distributed homogeneously in the respective component.
- polypropylene for example, so that every single fiber is completely covered by the thermoplastic material, so that the glass fibers are firmly embedded in the polypropylene and the polypropylene is distributed homogeneously in the respective component.
- the known composite bodies made of fiber-reinforced thermoplastic are successful and satisfactory, there is a desire for an even less impregnation of the glass fibers, an even better covering of the same by the polypropylene, for an even more homogeneous distribution of the plastic in the composite. body, and also after an even more rational manufacture of the composite body.
- the aim of the invention is to show a mat made of fibers, which is composed of first fibers made of a first material and second fibers made of a second material, at least some of the fibers being in the form of fiber strands made of fibers made of the first material and made of Fibers made of the second material are present, and which, when processed into a composite body, enables an extremely complete impregnation of the fibers made of the first material with the second material, and allows the first fibers to be properly encased by the second material, which second material is completely homogeneous in the Composite body is distributed.
- the mat according to the invention is characterized by the features of claim 1.
- the thermally deformable composite body produced from at least one mat is characterized by the features of claim 14.
- a method for manufacturing the mat is characterized by the features of claim 9 and a method for manufacturing the thermally deformable composite body by the features of claim 16.
- a method for producing a component from the thermally deformable composite body is characterized by the features of claim 18.
- FIG. 2 is a view of part of a mat formed from fiber strands
- FIG. 3 shows a view of a composite body produced from the mat according to FIG. 2
- FIG. 4 shows a mat formed from fiber strands and additional individual fibers
- 5 shows a mat with a carrier layer formed from fibers
- FIG. 6 shows a mat with a carrier layer formed from a film
- FIG. 7 schematically shows a device for producing the composite body according to FIG. 3,
- FIG. 8 shows a production variant
- FIG. 9 schematically shows a molding tool for producing a component from a blank cut out of the composite body according to FIG. 4.
- first fibers 1 shows a cross section through a fiber strand 3 which has a multiplicity of first fibers 1 made of a first material, for example glass, and a multiplicity of second fibers 2 made of a second material, for example polypropylene.
- the first fibers 1 can alternatively consist of carbon, aramid, boron, steel, PEEK (polyether ether ketone), PAN (high-strength polyacrylonitrile), flax, hemp, salis, jute, ramie, coconut and kenaf, this list is not final.
- the second fibers 2 can alternatively consist of thermoplastics, such as PP (polypropylene), PE (polyethylene), PA (polyamide), PET (polyethylene terephthalate) and / or mixtures of these thermoplastics. This list is also not exhaustive.
- Fiber strands 3 which contain fibers 1 made of, for example, glass and fibers 2 made of, for example, polypropylene, are freely available on the market and therefore do not have to be described in detail.
- a coherent mat is formed from a large number of the fiber strands 3 mentioned above.
- the fiber strands are placed in an endless or cut form on a flat surface. The underlying surface is laid and connected and solidified with one another in such a way that a mat is created.
- connection can be made by means of a needle known per se, with which a form-fitting connection of the individual fiber strands 3 is achieved to form a mat-shaped random fleece.
- chemical or thermal bonding is also provided. Only the fibers of one material have to be connected. It is assumed that the material of the second individual fibers 2 is a thermoplastic, e.g. Is polypropylene.
- the melting point of this second material is much lower than the melting point of the first material.
- bonding in particular with thermal bonding, only the second material is heated and thus brought into a molten state, and thus the molten polypropylene fibers, for example, melt together at their contact points.
- the glass fibers are not affected in any way. If an individual fiber strand is approximately rectilinear or only slightly curved, the individual glass fibers can be pulled out very easily, since they are arranged so as to be slidable relative to the polypropylene fibers in the fiber strand. In the finally formed mat, the glass fibers can still be pulled out individually, but this would be necessary due to this. the many strong curvatures of a greater application of force, so that the glass fibers practically do not shift during further processing to form the composite body, although there is no actual bond between the glass fibers.
- the glass fibers are preferably connected to one another at their contact points, and the same conditions apply to the polypropylene fibers that were described above in connection with the thermal bonding for the glass fibers.
- a section of the mat 4 (for example in the form of a random fleece) is shown schematically in FIG. 2. This mat 4 consists exclusively of fiber strands 3 held together. This mat 4 can now, for example when rolled up, be transported very easily and can be entered into corresponding devices in the form of webs in processing plants.
- FIG. 7 schematically shows parts of a plant for producing a composite body from at least one mat 4 made of fiber strands 3.
- the mat 4 is fed in a continuous processing process in the direction of arrow A to a first zone of the plant, which has, for example, a double belt press 5. Pressure and temperature are exerted on the mat 4 in this double belt press 5.
- the thermoplastic material e.g. PP melted and penetrates the other fibers, e.g.
- thermoplastic material is not from the outside, i.e. penetrate into the mat from the two main surfaces, but must be more or less evenly distributed within the mat, respectively. is arranged in the individual fiber strands of the mat, there is an excellent distribution of the thermoplastic material in the mat.
- the mat is solidified under cooling and pressure to form a compact, here web-shaped composite body 7. This composite body 7 is shown schematically in FIG.
- Fig. 3 shown. It has glass fibers 1 arranged in a tangled arrangement in a matrix 8 made of plastic are arranged so that there is now a thermally deformable composite body 7.
- the thickness of this composite body 7 is smaller than the thickness of the original mat 4.
- glass fibers are placed on a respective base and processed into a mat 4.
- the processing can be done by means of needles or cohesive connection techniques.
- Such a mat 4 which is needled as an example, is shown in FIG. 4. It therefore has fiber strands 3 made of glass and PP fibers and additionally fibers 10 made of glass, that is glass fibers.
- the additional fibers 10 consist of PP.
- the glass fibers are advantageously deposited in the form of known glass rovings and the PP fibers in the form of multifilaments.
- additional polypropylene can be added to the mat 4 only immediately before it enters the double belt press.
- This variant is drawn in FIG. 8.
- additional polypropylene is fed in the form of one (or more) film web (s) 15, or also in the form of (at least) a melt film.
- film web (s) 15 or also in the form of (at least) a melt film.
- Needling should therefore be reduced to a minimum.
- the mat that is ultimately to be processed into a composite body must still be able to be handled and be transportable.
- the fiber strands 3 are placed on a tangled nonwoven 13 (also called nonwoven in technical terminology) made of PP (that is, not needled to one another) and only fixed on the tangled nonwoven 13 with the minimum number of needle sticks required for the subsequent handling, as drawn in FIG. 5.
- a tangled nonwoven 13 also called nonwoven in technical terminology
- PP that is, not needled to one another
- a thin PP film web 14 a PP film
- the connection between the fiber strands 3 and the film web 14 takes place by means of minimal needling.
- the random fleece 13 can also consist of glass fibers, that is to say the first material.
- the composite body 7 can now be made into final components, e.g. for road vehicles. Reference is made to FIG. 9.
- Blanks 9 corresponding to the component to be manufactured are produced from the composite body 7. Depending on the subsequent processing, only a single blank 9 or multiple blanks are used together in the form of a blank structure.
- the blank structure consisting of a blank 9 or more blanks corresponds in weight to the weight of the finished part of the component to be manufactured.
- the blanks 9 are reheated in a known manner in a continuous manner in heaters, for example infrared ovens, so that the thermoplastic component of the blank structure from one or more blanks 9 again becomes flowable. Then a respective heated blank structure or blank 9 is inserted into a molding tool, which has, for example, a female mold 11 and a male mold 12, and the molding tool is closed, as indicated by the arrow B. The blank is pressed under pressure in the molding tool and then cooled, so that the component to be produced is finally shaped.
- heaters for example infrared ovens
