Definitions
- the invention relates to a yarn of at least two mutually wound strands of continuous carbon fibers, a process for the preparation and the use of such yarns.
- textile preforms for example for technical applications, such as fiber composites, filter media, u.a. suitable sewing threads necessary.
- These yarns are intended to fix the preform, but increasingly also structurally reinforce, even at very high temperatures, as required for example in the production of fiber ceramics or when used as filter media in chemically and / or thermally highly loaded processes.
- This yarn is made with 1000 filaments or two components each with 1000 filaments or three components with 1000 filaments each.
- the fermentation rotation of the individual components is about S222-224 t / m.
- these strands are wound around each other at approximately Z162-Z164 t / m.
- the production of this twist is probably possible in a normal twisting process with many abrasive thread deflections only with thin and thus flexible filaments in a diameter of about 5.5 microns or less.
- the production of carbon fibers with a diameter of less than 6 microns, however, is very expensive, so that this type of yarn is very expensive.
- sewing threads have been developed which have a core of carbon fibers and are additionally sheathed with another yarn (see, for example, US Pat JP-A 2133632 or JP-A 1061527 ).
- This sheathing can be done by various methods, for example by winding or crocheting. Since wrapping means a heavy burden on the yarn material, this z.
- these yarns have a low composite adhesion to the plastic matrix and reduce the fiber volume fraction of carbon fibers in a fiber composite material by the proportion of Umwindegarne.
- the core materials of the sewing yarns can not be placed close enough to the fabric because the bulky sheath is located therebetween.
- EP-A-0 303 381 describes a yarn of two, mutually wound strands of continuous carbon fibers at about 50 t / m.
- glass twists, aramid or so-called PBO fibers are used for sewing, since they have a higher transverse strength than carbon fibers and in this way survive damage to the abrasive sewing process.
- their printing properties or their mechanical properties in combination with a matrix, such as plastic are considerably lower than at Carbon fibers, so that a real structural reinforcement can not be achieved.
- the filaments of filament yarn fibers are parallel in the yarn after production and thus form only a small cohesion to a closed yarn structure.
- twists are introduced into filament yarns. This usually additional manufacturing step means a first damage to the filaments, which then in the subsequent sewing process cause further filament damage to the thread breakage.
- the object of the present invention is therefore to provide yarns of endless carbon fibers in which the disadvantages described above are at least reduced.
- the yarns should be better suited for use as sewing threads than those previously available on the market.
- the object of the invention is achieved in that the yarn has at least two, mutually wound strands of endless carbon fibers, wherein the carbon fibers of the strands are arranged at least almost parallel to the yarn direction.
- carbon fibers are understood to mean endless carbon fibers (carbon fiber filaments).
- the arrangement of the carbon fiber in a single processing step which is selected almost parallel to the yarn axis, achieves that the loss of strength as a result of the filament breaks during the two-stage twisting process caused by the mutual winding of the strands in the two-stage twisting process Production or otherwise unavoidable skew of the filaments in the yarn in a single-stage twisting method significantly lower fails.
- the yarns according to the invention can be produced by producing them by direct cabling of at least two carbon fiber strands.
- This direct cabling has hitherto been used only for the production of tire cord (see, for example WO 02/103097 ).
- the Swiss Sea by which the strands used to produce the yarn according to the invention are wound around each other, in the region in which a contact with the strands, a radius of at least 4 mm, preferably 4 to 40 mm, especially preferably at least 6 to 12 mm.
- each of the thread guide elements used in a direct cabling machine has a radius of at least 4 mm, preferably 4 to 40 mm, in the region in which contact takes place with one or more of the strands or with the finished yarn , more preferably 6 to 12 mm.
- the yarn of the invention can be produced with the normal knowledge required for direct cabling.
- the surface of the Caribbeanungsinate is coated with a plasma coating in the composition of 97% Al2O3 and 3% TiO2, which is subsequently polished.
- the direct cabling of the precursor that is to say of the fibers which are further processed by oxidation and / or carbonization into carbon fibers, can also take place, after which the oxidation and / or carbonization takes place. It is also conceivable to withdraw all intermediate products of carbon fiber production from the process, to direct-cofacilitate and then to feed it back into the carbon fiber production at the removal point. In particular, the intermediates prior to carbonization are particularly suitable for this purpose.
- the yarn according to the invention is characterized in particular by an average abrasion resistance of from 50 to 350, preferably from 175 to 300.
- the abrasion resistance is measured by the following method:
- a yarn G is clamped in a yarn clamp 7 and, corresponding to the yarn course in FIG FIG. 1 passed through a sewing needle 5 and loaded on the other, free yarn end with a weight 6 of 10 g.
- a crosshead 1 with the sewing needle 5 cyclically and horizontally by a stroke of about 75 mm.
- the cross member 1 is mounted on a bearing 2 via a bearing 4.
- the stroke of about 75 mm is limited by stops 3 'and 3 ", which process about 60 strokes per minute.
- the yarn G - due to the ever-changing distance between the yarn clamp 7 and needle eye of the needle 5 - is moved through the needle eye of the needle 5 and thus undergoes a scuffing load.
- the number of strokes executed until then is recorded. This measurement is performed on eight different yarn sections. At the end of the test, all eight values are averaged and rounded to an integer number. This integer number is given as a measure of the average rub resistance.
- the measurement of the average abrasion resistance is excellent for judging the sewing properties of the tested yarn.
- the knot strength is measured according to DIN 53842, however, the yarn ends are fixed with cardboard hoppers before they are clamped in the tensile testing machine. In addition, no preload force is adjusted due to the brittleness of the material.
- the yarn according to the invention is distinguished by the fact that the carbon fibers in the strands have a diameter of 3 to 10 ⁇ m, in particular 6 to 10 ⁇ m.
- yarns B and C give the best results in terms of shear strength and knot strength. They are therefore also ideally suited as sewing threads.
- the fiber-matrix connection is particularly important for the mechanical material potential.
- a prepreg was prepared from yarns B and C in conjunction with a resin film, and the compressive strength was measured according to EN 2850-B2 and the apparent interlaminar shear strength according to EN 2563 ,
- a prepreg film (HexPly 6376 prepreg film from Hexcel Composite, Dagneux (US Pat. France)) with a basis weight of 72 g / m 2 applied.
- the yarn is wound on this film with a laboratory winding machine perpendicular to the winding axis with a yarn tension of 500 cN and a winding speed of 23.1 mm / s so that a UD structure is formed.
- the layers are again wound with a prepreg film having a basis weight of 72 g / m 2 .
- This entire UD structure and the metallic core are heated in an oven under constant rotation - in 20 minutes at 80 ° C, held for 20 minutes below 80 ° C and cooled to room temperature in 60 minutes.
- the resulting UD body is cut open at the eight edges, resulting in 8 platy preprep materials.
- These prepreg materials are further processed according to the standards EN 2850-B2 and EN 2563 into multilayer laminates in an autoclave and a conventional vacuum structure and tested under standard conditions.
- yarns B and C of the invention have similar high apparent interlaminar shear strength and compressive strength to conventional carbon fiber yarn E.
- the cabling process of the present invention does not significantly deflect the filaments of the yarn from their orientation parallel to the yarn longitudinal axis otherwise the pressure characteristics would have dropped.
- Comparative yarn F which has a core of carbon fiber filaments and a crocheted jacket of polyester yarn, exhibits significantly poorer compressive strengths.
- the load-absorbing carbon fiber filaments are therefore no longer stretched along the yarn longitudinal axis and therefore fail faster at a pressure load.
- the polyester sheath obstructs the necessary adhesion between load-bearing carbon fiber and matrix material.
- the second comparative yarn G is outstandingly sewn on account of its high transverse strength and its ductile material behavior, it has very low shear and compressive strengths, so that a reinforcing effect in fiber composite materials is not to be expected.
- test specimens are produced and tested in accordance with EN 6038. Notwithstanding EN 6038, the test specimen produced has a wall thickness of 4 mm, while the test was carried out with a span of 15 mm. To this end, four layers of quasi-isotropic, four-layered multiaxial layers (NCF, 267 g / m 2 fiber surface weight of the scrubland cell) are sutured. The sewing is done with the above-mentioned yarn C with a stitch length of 4 mm, a seam spacing of 3 mm and a stretched lower thread in the lockstitch (also yarn C).
- NCF quasi-isotropic, four-layered multiaxial layers
- the resulting textile preform with a square base area of 315 mm 2 and a wall thickness of 4 mm is impregnated with RTM6 resin from Hexcel in compliance with the resin manufacturer specifications so that a pore-free fiber composite material with a fiber volume fraction of 60 ⁇ 4% , Test specimens were sawn and tested from this plate according to the test standard EN 6038 (hereinafter referred to as "NCF sewn").
- prepreg an analogously constructed prepreg laminate (16 layers each with 267 g / m 2 fiber surface weight of the prepreg single layer, mirror symmetrical to the median plane of a resin film (HexPly 6376 from Hexcel Composite, Dagneux (France)) and carbon fibers (Tenax HTS 5631 800tex applicant's application number f12000 t0) (hereinafter referred to as "prepreg").
- Table 3 shows the results of the test (residual compressive strength after impact according to EN 6038 in [MPa]) with the yarn according to the invention (NCF sewn) in comparison to an unvarnished multiaxial fabric (NCF unwown) and an analogously constructed laminate (prepreg).
- the yarn of the present invention can be used in virtually all matrices reinforced with fibers.
- Suitable matrix materials include polymers such as thermoplastics (eg, polyethyleneimine, polyetherketone, polyetheretherketone, polyphenylene sulfide, polyethersulfone, polyethersulfone, polysulfone), duromers (eg, epoxies), elastomers, and rubbers.
- thermoplastics eg, polyethyleneimine, polyetherketone, polyetheretherketone, polyphenylene sulfide, polyethersulfone, polyethersulfone, polysulfone), duromers (eg, epoxies), elastomers, and rubbers.
- ceramic materials eg silicon carbide or boron nitride
- metallic materials eg steel (alloys), titanium
- Thermoplastics and thermosets are particularly suitable because the necessary fiber-matrix adhesion between these polymeric materials and the carbon fiber is particularly good. But also the reinforcement of elastomers and rubber with the yarns according to the invention is advantageous since normally carbon fibers have a high strength but not those in these materials usual elongation properties. Due to the yarn structure of the yarns according to the invention an improved extensibility is possible and in this way an improved reinforcing effect in elastomer and rubber materials.
- the direct cabling of carbon fibers can be used not only for the production of sewing threads but also, for example, for the production of yarns for concrete reinforcement. For example, if strands are selected for direct cabling, of which one strand has a higher thread tension than the other strand, then in direct cabling the one or more strands having the lower thread tension will wrap around the strand or strands with the higher thread tension. In this way, a yarn with a kind of ribbing, as they have, for example, reinforcing bars for the reinforcement of reinforced concrete. Thus, a mechanical anchoring of the yarn in the concrete is possible.
