Definitions
- the present invention relates to a new molding process, i. H. Three-dimensional molded articles with functional stiffness are produced from flexible textile substrates by coating shaped fabrics.
- the flexible textile substrates are stiffened by thermal spraying, in particular by wire flame spraying and / or arc spraying and / or high-speed spraying (HVOF) and / or by plasma spraying.
- the functional rigidity of the molded part can be achieved by different application thicknesses or quantities. It is essential that the molded body produced by means of the usual connection techniques such. B. welding, screws, etc. can be reconnected with other moldings.
- the present invention further relates to an asbestos-free or other inorganic fibrous substances, with fiber lengths of> 5 microns, a diameter of ⁇ 3 microns, a length / diameter ratio of 3: 1, free flat composite material, that is, a molded body consisting of at least a first layer consists of a textile lattice fabric, mesh, knitted fabric, knitted fabric or fleece and at least one second layer made of metal and / or ceramic applied to this first layer.
- the molded body is characterized by a functional stiffness and is mainly used as a soft tissue compensator, as a smoke apron, as a fire baffle molding (fire baffle block), as a molded body for thermal shielding in the automotive industry, as a bumper or as a load-bearing component in lightweight construction.
- Asbestos and all inorganic fibers artificial mineral fibers
- ie also ceramic fibers within a certain fiber distribution spectrum with certain fiber lengths have health-endangering effects.
- the harmful effects of asbestos have been known for a long time.
- Glass fiber fabrics and / or glass nonwovens come into consideration as a possible substitute material.
- Such uncoated glass fiber fabrics have no flame deflection properties due to the open-pore structure, but rather flame absorption properties.
- such fabrics are not dimensionally stable, which leads to erosion and erosion at high hot air speeds.
- Products of this type typically consist of, for example, vacuum-formed ceramic fiber composite materials. Such products are currently made with ceramic fibers manufactured that are respirable and therefore must be classified as a K2 hazardous substance (carcinogenic potential).
- the high temperature (according to the ETK according to DIN 4102) is normally broken down or isolated over several layers of an insulation material until appropriate gas-tight but low-temperature-resistant polymer membranes can ensure the low leakage.
- Such a fabric-reinforced elastomer compensator is known from DE 38 20 922 C2.
- This compensator contains fluororubber as an elastomer component and as reinforcement a textile mesh made of aramid fiber and / or E-glass fiber in combination with the fluororubber elastomer component.
- Rigid sheet metal parts are currently used for the above-mentioned purposes, which are deep-drawn for insulation purposes as a sandwich sheet with an insulation insert.
- Polymer-coated glass fabrics or laminated glass fabrics are often used as cable insulation.
- Rigid sheet metal parts offer the advantage that due to the dimensional accuracy of rigid molded parts, movable components or other assemblies can be safely guided past.
- such shields are complex to manufacture due to the corresponding forming processes and are comparatively difficult. Due to the vibration behavior, they also offer the risk of touching neighboring components and thus the problem of noise.
- vibration engineering perspective such as Fatigue, vibration and breakage of sheet metal parts, rigid components not a suitable material.
- a later revision or assembly of adjacent components can be restricted or prevented by a rigid component.
- polymer-coated textile fabrics show a lack of temperature persistence and the problem of the flammability of the applied coating.
- Coatings are therefore known from the prior art, which are basically carried out with polymeric binder or basic systems. However, these often have disadvantages for certain areas of application.
- the organic content of accompanying substances leads to loss of ignition, smoke and odors when exposed to temperature.
- the present invention is therefore based on the object of providing a new process for the production of moldings with functional stiffness from flexible textile substrates.
- the flexible textile substrates are to be made from fibers classified as harmless to health.
- These new moldings are said to be able to be used in various fields of application, such as in the motor vehicle industry, ie in vehicle construction or in robotics, and to replace the moldings which have been customary to date.
- This object is achieved according to the invention by a process for the production of moldings with functional stiffness from flexible textile substrates, the moldings being non-positively, materially and positively connectable to other moldings, with thermal spraying of molten, metallic and possibly ceramic particles onto at least one Textile lattice fabric web, a mesh, knitted fabric, knitted fabric or a nonwoven soaked this textile substrate, so that an intimate connection of the metallic and possibly ceramic particles sprayed on in the molten state is produced partly with the fabric fibers and partly with one another an intimate connection and by integrating the fibers, a stiffness is achieved, the flexible, textile substrates essentially consisting of fibrous substances or fibers made of asbestos or inorganic fibrous substances with fiber lengths with a length> 5 ⁇ m, a diameter ⁇ 3 ⁇ m and a length e-to-diameter ratio of> 3: 1 are free (see claim 1).
- flexible textile substrates can be converted into moldings with functional stiffness by coating woven fabrics. This is due to the fact that the metallic and possibly ceramic particles sprayed on in the molten state enter into an intimate connection partly with the fabric fibers and partly with each other. This creates a layer or a shaped body which is relatively flexible and can therefore be deformed within wide limits without the risk of crack formation.
- the molded body according to the invention can be non-positively, materially and positively with other molded bodies by conventional connection techniques, such as. B. welding, screwing, etc. are connected. This is achieved by partially applying thicker layers around the joints.
- This composite material according to the invention or the molded body consists of at least a first layer of a textile lattice fabric, mesh, knitted fabric, knitted fabric or fleece made of aramid fibers and / or E-glass fibers and / or silicon dioxide-rich glass fibers and / or carbon fibers and at least one on this first layer by means of plasma spraying, by means of flame spraying and / or plasma coating applied second layer of metal and / or ceramic.
- the flat composite material according to the invention or the shaped body can either be a soft material compensator, a fire impact molded part, a shaped body for the motor vehicle industry or a load-bearing component in lightweight construction.
- moldings in the automotive industry are e.g. Heat shielding parts in the area of the engine block of a motor vehicle or bumper.
- cable harness insulation and lever arms are considered as areas of application in robot technology.
- the composite structures according to the invention can also be used as stabilizing components in vehicle construction. By partially thickening the coating, welded connections or other types of connections such as screw connections can be made at certain points.
- the molding can be adjusted in terms of rigidity by partially thickening the coating. Through a continuous transition from metal to textile, according to the invention, a gradient material with correspondingly different properties from soft, flexible to stiff, dimensionally stable is created.
- the coating of fabrics also prevents fraying and the displaceability of the glass fabric fibers.
- the first layer of the textile substrate can consist of one or more layers.
- all textile fibers in particular aramid fibers and / or E-glass fibers and / or silicon dioxide-rich glass fibers and / or carbon fibers, can be considered as material here.
- the silicon dioxide-rich glass fibers have an SiO 2 content of over 95%. Textiles made from silicon dioxide-rich glass fibers are therefore very temperature-stable, ie up to 1100 ° C.
- Nonwovens ie so-called needle mats
- the textile fabrics used as “substrate” according to the invention have no flame deflection properties, but rather the opposite of flame absorption properties. Therefore, according to the invention, a coating of metal and / or ceramic is applied here by means of thermal spraying, in particular wire flame spraying, arc spraying, plasma spraying Coating, in particular made of aluminum or high-tempered steel, eg V4-A steel or chrome-nickel alloys, has a stabilizing effect on the final shape at the same time. However, this depends on the thickness of the metal coating, which can range from 0.1 to 5 mm, in particular 0.1 to 1.4 mm.
- the coating prevents the erosion of the fibers and their removal at the high hot air speeds that occur here. In addition, the coating reverses the flame and stabilizes the shape.
- a textile web is used as the substrate.
- This web has already been made by means of thermal spraying, i.e. in particular with wire flame spraying and / or arc spraying and / or plasma spraying with a layer of metal such as e.g. Aluminum.
- a flat blank is then produced from this coated web.
- This flat blank can then in turn be coated with metal on the back. It is advantageous if the cut edges are also coated with metal. According to the invention, it is therefore possible to coat the textile fabric web continuously or discontinuously or as a blank or as a die cut.
- a molded body such as, for example: a soft material compensator, a fire impact molded part or a molded part for the motor vehicle industry, can thus be produced.
- the flat composite material according to the invention or the molded body can, as already explained above, be a soft material compensator, a fire impact molded part or a molded part for thermal shielding in the motor vehicle industry.
- a suitable drapable fabric was drawn into a three-dimensional structure and fixed by vacuum deep drawing.
- the fabric structure is fixed by uniformly applying a thin coating layer of approx. 75 g / m 2 aluminum.
- the coating process also makes it possible to locally increase the quantity of the coating.
- the process control enables this support thickness to be built up to several centimeters. This is used in order to achieve stiffening up to absolute dimensional stability and hardness in places that are statically important for the molded body. This also applies to positions in the molded body where a movable component must be guided safely and functionally.
- a coating quantity can be selected at other points on the molded body that meets the requirements of absolute fiber integration and thermal shielding and tightness in such a way that the textile and flexible character of this section is nevertheless retained.
- the transition zones between soft, textile, flexible zones and shaping and shape-stabilizing, hard zones of the molded body correspond to a continuous material transfer in the sense of a gradient material.
- Gradient materials can not only be created in such a way that a gradient is achieved with regard to the amount of support, but also when using the coating materials.
- a pre-coating with another, more ductile metal z As zinc, on the one hand, the adhesion of the coating on the textile backing, on the other hand, the brittleness of the coating can be influenced by z. B. to be able to design tight radii within a molded part.
- Precoatings are usually used here in the application quantity of approx. 50 g / m 2 . Of course, these precoatings can also be applied locally so that they can then be coated with an appropriate top layer, e.g. B. Aluminum to be sealed.
- the term gradient material refers not only to different coating quantities but also to different coating materials that can be applied continuously and functionally.
- thermal shielding does not always have to have the character of a preformed component. Often, simply by choosing the attachment points one Shape realized.
- Such solutions have traditionally already been implemented with the textiles described above with a polymer coating.
- the lack of temperature persistence of the coating and the flammability such products also have disadvantages in terms of fastening technology and heat radiation (IR emission).
- IR emission heat radiation
- the screw bushings must be secured with eyelets, because if the temperature is high, the pull-out strength achieved by the coating in the fastening points is completely lost due to the destruction of the coating.
- the molded parts according to the invention have temperature-permeable coatings and can additionally be reinforced in the fastening points (gradient coating). They therefore offer absolute security against tearing out.
- the molded body according to the invention can be produced by a coating layer of approximately 300 g / m 2 as a cold-deformable material, which in turn offers easier assembly and stability due to the preformability.

- a plain-weave glass fabric isoGLAS ® fabric type 1115 was continuously coated in a width of 33 cm on both sides with elemental aluminum using the wire flame spraying method.
- a spray gun was mounted on a controllable traversing device. At the same time, the tissue was moved further in the longitudinal direction.
- the distance from the spray head to the fabric is 200 mm.
- the diameter of the spray cone is 20 mm with very little overspray. In the configuration mentioned here, a coating speed of approx.
- the amount of coating selected here was 150 g / m 2 per side.
- the finished article is approx. 300 g / m 2 with a total weight of the finished article of approx. 1400 g / m 2 .
- any amount of aluminum can be applied through several coating passes. Concrete tests on different fabrics and nonwovens show coating layers on one side from 500g / m 2 up to approx. 1000g / m 2 , which corresponds to a layer thickness of approx. 1.4 mm. With articles of this type, the flexibility decreases; Here, however, a corresponding dimensional stability can be achieved.
- the temperature-independent low leakage is achieved on the one hand (synonymous with a constant tightness over the application temperature range). On the other hand, despite the coating, you get the necessary flexibility and mobility of the article.
- the coating also increases the dimensional stability of the fabric; however, this also results in a significantly improved ability to be assembled. This means in particular an improved cutting possibility without fraying warp or weft threads; At the same time, the cut edges are partially sealed by pressing or squeezing the cut zone with the aluminum applied as a coating.
- a tube made of silicon dioxide-rich glass fibers was pulled onto a rotating metal shaft and attached to it.
- the process of thermal spraying first applied a uniform, thin layer (approx. 75 g / m 2 aluminum to stabilize the hose ) to the hose. Subsequently, a much thicker support was implemented. In the specific case, this was approx. 1.5 cm wall thickness The transition from the thinly coated surface to the end areas was continuous.
- the textile carrier hose is used to isolate the temperatures transmitted by the hot flue gases and in conjunction with the coating to seal the flue gas.
- the textile hose in the intimate material combination of metal and textile ensures the resulting rigidity and stability of the entire part.
- the applied material was machined (turned) in the edge areas of the compensator, so that a connecting flange or a connecting sleeve is created.
- connection techniques With the help of this continuous transition from flexible, movable assemblies to rigid and stable zones, the problem of connecting such fiber composite or gradient materials can be solved elegantly. Both screwed, flanged or welded are used as connection techniques
- a tube made of p-aramid fibers was pulled over a rotating shaft and coated in the same way as described in Example 2.
- the layer thickness initially applied evenly over the entire width of the hose is more than 400 g / m 2 .
- the end regions are then massively reinforced locally, so that a machining treatment can also be carried out here in a further processing step.
- the end product must also be referred to here as a gradient material because of the continuous transition from the inner part of the tube to the outer area. Due to the fiber composite structure of metal and aramid fibers, however, a stable, lightweight structural component is produced, the connection to other components in turn by welding. Flange technology or screws can be solved optimally.
- the use can e.g. B. as a lever arm in robotics; can be used as a stabilizing component in vehicle construction.
- isoTHERM ® S material which is temperature stable up to 1100 ° C, was used as the textile fabric. These are silicon dioxide-rich glass fibers with an SiO 2 content of over 95%. Nonwovens made from isoTHERM ® S, ie so-called
- Needle mats can be produced up to a thickness of 75 mm as very compact sheets.
- nonwovens of this type have no flame deflection properties due to the open-pore structure, but rather the opposite, flame absorption properties, a solution can only be achieved here by a suitable closed, temperature-stable coating.
- the coating must also have a stabilizing effect on the final shape; this coating must also prevent the erosion of fibers and their removal at the high hot air speeds that occur here.
- a above-described standard fleece with a thickness of 45 mm and a density of> 200 kg / m 3 was mechanically pressed and punched into the specified shape.
- the wire flame spraying method A1 2 0 3 was then sprayed onto the surface prepared in this way.
- the order quantity in the concrete area is approx. 300-500g / m 2 .
- the distance between the spray nozzle and the fleece is 110 mm.
- the coating is also achieved very evenly by the traversing movement of the spray gun and the horizontal movement of the spray gun.
- Smoke aprons made from Mtex- »(trade name from Frenzelit, Germany for technical textiles coated with metals) were made from a V4A wire-reinforced glass fabric.
- this fabric was initially evenly coated on both sides with a coating layer of approx. 150-200 g / m 2 aluminum. About the fabric width vzw. Subsequently, an approximately 20mm wide strip was coated to a final thickness of 2mm, thus stiffening and stabilizing. This was done in a continuous process, depending on the desired length of the curtain, e.g. B. 2m performed repeatedly in this way.
- the fabric edges were also reinforced to a width of approx. 20mm up to a coating layer of approx. 400g / m 2 .
- the 2mm thick thickening across the fabric width serves to securely fasten the curtains to the upper shaft; the edge reinforcement enables the combination and the joining together of several identical, cut lengths.
- the fastening techniques available here fall under the structure of non-positive, positive or material. Similar to the products described above, the term gradient material also applies here, due to the smooth transition towards the edge and transverse stiffeners and the basic preservability of the rollability of the textile web, with the advantage that the known, proven rolling devices can be retained.
- Such smoke aprons serve vzw. in industrial plants and large halls for the sectioning of large rooms for better removal of the smoke and smoke that occurs in the event of a fire.
- Fire protection devices of this type which are common today are either in the form of stable sheet metal ducts or in the form of roller shutters which are only triggered and moved down in the event of a fire.
- roller shutter solutions exist today vzw. from glass fabrics which are additionally polymer-coated for reasons of manageability and assembly. This is accompanied by the known problems such as flame retardancy or even flammability, smoke development of the coating in the event of a fire; and problems with the fastening technology and the stability of the fastening under fire conditions.
- the types of fastening can be designed to be temperature stable and non-flammable; the product is to be classified as non-flammable due to its consistently inorganic structure as AI.
- V4A wire-reinforced glass fabrics were used as the carrier fabric Commitment.
- these are first coated with aluminum evenly over the entire filter surface.
- 200 g / m 2 of aluminum can be regarded as a typical support quantity in the area of the filter surface for the carrier fabrics used here.
- the porosity, or the pore volume, and the pore size distribution can be varied in this method via the parameters of thermal spraying, such as spraying distance and application quantity, etc. Furthermore, these parameters are influenced by the type of weave, the fabric density and the fiber materials.
- This molded body can also be referred to as a gradient material.
- the gradients can be generated by different metals, as well as by the continuous transition from rigid, rigid structures to softer, in this case permeable areas. Gradient materials are thus created from the point of view of gradually different porosity between the rigid edge areas and the filtration surface.
- a suitable drapable fabric was drawn into a three-dimensional structure and fixed by vacuum deep drawing.
- the fabric structure is first fixed by uniformly applying a thin coating layer of approx. 75 g / m 2 aluminum.
- the coating process also makes it possible to locally increase the quantity of the coating. In principle, the procedure enables this support thickness to be built up to several centimeters. This is used in order to achieve stiffening up to absolute dimensional stability and hardness in places that are statically important for the molded body. This also applies to positions in the molded body where a movable component must be guided safely and functionally.
- a coating quantity can be selected at other points on the molded body that meets the requirements of absolute fiber integration and thermal shielding and tightness in such a way that the textile and flexible character of this section is nevertheless retained.
- the transition zones between soft, textile, flexible zones and shaping and shape-stabilizing, hard zones of the molded body correspond to a continuous material transfer in the sense of a gradient material.
- 3 and 4 show the heat shielding part produced according to the invention.
