Definitions
- the present invention relates to a thermoplastic fiber material spun from a raw material containing polyhydroxyether, a process for its preparation, and particular uses therefor.
- melt spinning process For the production of synthetic fibers from polymers, the melt spinning process is preferred today, because it is particularly economical. Only polymers which can not be melt-removed will be limited to other spinning processes such as e.g. resorting to solution spinning.
- Melt spinning presupposes that the polymer to be spun is thermoplastic and that it is sufficiently stable in the melt state under pressure and at the required extrusion temperature, that is, it does not degrade, build or crosslink.
- Polyhydroxyether is a thermoplastic polymer that excellently adheres to many materials and, because of this property, is popular for a variety of applications. At elevated temperatures, however, it is very unstable, which is according to US 3,375,297 limits or even prevents its use in cases where resistance to elevated temperatures is required. Consequently, difficulties are to be expected especially in melt spinning, since the extrusion temperature must be much higher than the softening temperature because of the fine capillaries in the nozzle plate of the spinneret than in other extrusion processes.
- synthetic fiber yarns especially polyester yarns (PET) are used as auxiliary yarns to stabilize the reinforcing fibers prior to embedding them in the matrix.
- PET polyester yarns
- UDs mat-shaped unidirectional layers
- the auxiliary thread is used to fix the mutually parallel reinforcing fibers in their parallel position and thereby make the clutches as a coherent mats.
- LM Liquid Molding
- RV Resin Transfer Molding
- VARTM Vacuum Assisted Resin Transfer Molding
- RFI Resin Film Infusion
- LRI Liquid Resin Infusion
- RIFT Resin Infusion Flexible Tooling
- the auxiliary thread has various disadvantages in the finished component.
- the reinforcing fibers are kinked at the crossing points with the auxiliary thread, whereby they are not oriented ideally in the main force flow direction, which can lead to a significant weakening of the component. Its different physical properties, such as its different thermal expansion coefficient, can weaken the component.
- Other disadvantages that can occur are shrinkage or a rough surface of the component.
- GRILON® melts from EMS with low melting point, ideally 60 ° C or 85 ° C. These semi-crystalline yarns melt during curing of the matrix and, depending on the conditions, partially or completely dissolve, so that the reinforcing fibers can better be arranged in the component.
- the polymeric melt yarn material remains in the component in addition to reinforcing fiber and matrix as a third phase as such. With its other physical properties, such as In turn, a different thermal expansion coefficient, it weakens the component.
- Polyhydroxy ether sizing agents adhere well to the major reinforcing fibers such as glass fibers and carbon fibers and are compatible with conventional matrix systems based on epoxy, unsaturated polyester, cyanate ester, urethane, phenol, formaldehyde, melamine, or combinations thereof. They are usually applied as aqueous polymer dispersions. They are not suitable for stabilizing the reinforcing fibers or a preform made therefrom before they are embedded in the matrix.
- the present invention is based on the finding that polyhydroxyethers, despite their low stability to elevated temperatures, can be produced economically even by melt spinning in an economical manner a thermoplastic fiber material having a substantially amorphous structure, which with particular advantage for stabilizing the reinforcing fibers or a thereof prepared preform before it is embedded in the matrix of fiber composites.
- the polyhydroxyether fiber material dissolves completely in the matrix material at a temperature above its glass transition temperature, thus, for example, the kinking problem with respect to the Reinforcing fibers is eliminated.
- it crosslinks with the matrix material when it hardens to a homogeneous matrix.
- the crosslinking takes place on the basis of as well as on the OH-groups repeated many times along the molecular chain.
- the polyhydroxyether fiber material is thus integrated into the matrix and can no longer adversely affect the mechanical properties of the component.
- the result is a composite material consisting of only the two phases, namely reinforcing fiber and matrix. The problem of incompatibility of matrix and auxiliary thread or auxiliary thread material is eliminated.
- thermoplastic fiber material spun from a raw material containing polyhydroxyether, wherein the raw material contains polyhydroxyether as a single polymer, wherein the polyhydroxy ether has a substantially amorphous structure, a molecular weight Mw of 10'000 to 80 ' 000 Daltons and a glass transition temperature T g of not more than 100 ° C.
- Molecular weight Mw means the weight average of the molecular weight. This value is preferably 20,000 to 60,000 daltons, in particular 30,000 to 55,000 daltons. These polymers are thermoplastic and linear in contrast to the chemically related epoxy, which is of great importance for fiber spinning. Under suitable cooling conditions they solidify completely amorphous. This is advantageous in the above-mentioned use for stabilizing the reinforcing fibers (or a preform made therefrom) prior to their embedding in the matrix of fiber composites, because they are easier to dissolve. Its glass transition temperature Tg (DSC) is typically between 84 ° and 98 ° C and is preferably less than 95 ° C, and more preferably less than 90 ° C.
- a polyhydroxy ether can be used in which with short, grafted polycaprolactone side chains (eg
- the glass transition temperature Tg has been reduced e.g. to a value between 30 and 80 ° C, so that this is a few degrees below the curing temperature.
- a reduction of the glass transition temperature Tg can also be achieved by adding a plasticizer.
- the fibrous material according to the invention may be a monofilament or contain such, e.g. having a linear density of 20-12,000 dtex, preferably 100-3,000 dtex, and more preferably 200-1,500 dtex.
- the fibrous material of the present invention may be or may contain a multifilament yarn having a plurality of single filaments, e.g. with a total titre of 20-5,000 dtex, preferably 100-1,500 dtex.
- the number of individual filaments is e.g. 10-120, preferably 20-50.
- the fibrous material according to the invention may also be a staple fiber or contain such and, e.g. be further processed by conventional spinning processes to ring yarn, compact yarn, rotor yarn or carded yarn.
- textile fabrics such as woven fabrics, knitted fabrics, knitted fabrics, nonwovens, felts, scrims or the like.
- the unit m 3 / kg means that it is the specific blast air consumption relative to the polymer throughput, ie the ratio of the blast air flow rate (in m 3 blast air per unit time) to the polymer mass flow (in kg per same time unit), the throughput goes through the spinning machine or is produced in the form of polymer threads.
- the melt spinning method according to the present invention may include a method of spinning cables followed by stretching and cutting into staple fibers, a process of single-stage staple fiber staple stretching, bulk continuous filament spinning (BCF), filament spinning of partially oriented yarn (POY) or fully drawn yarn (FDY), electrospinning of microfibers, or even a process of spinning monofilaments in air or in a water bath.
- BCF bulk continuous filament spinning
- POY filament spinning of partially oriented yarn
- FDY fully drawn yarn
- electrospinning of microfibers or even a process of spinning monofilaments in air or in a water bath.
- thermoplastic fiber material according to the invention could be produced only by melt spinning.
- the stated melt spinning process is preferred because of its economy.
- thermoplastic fiber material as defined above as according to the invention in the manufacture of components from Fiber composites with embedded in a matrix reinforcing fibers for fixing the reinforcing fibers in a defined geometric arrangement before their embedding in the matrix.
- the reinforcing fibers can in this case be fixed with a thread made of the thermoplastic fiber material, in particular by embroidery, sewing and / or weaving techniques.
- the reinforcing fibers can also be fixed with a textile fabric made of the thermoplastic fiber material by such a sheet, in particular in the form of a so-called nonwoven fabric made of staple fibers, e.g. sandwiched between the layers of a multi-axial web of reinforcing fibers.
- a textile fabric made of the thermoplastic fiber material by such a sheet, in particular in the form of a so-called nonwoven fabric made of staple fibers, e.g. sandwiched between the layers of a multi-axial web of reinforcing fibers.
- a stabilized preform is to use a sheet, e.g. a fabric or a scrim, consisting of a mixture of reinforcing fibers and polyhydroxyether fiber material according to the invention in a hot press above the softening temperature of the polyhydroxyether fiber material to press and shape.
- the polyhydroxy ether melts fiber material and serves as a hot melt adhesive which stabilizes and holds together the preform after cooling and solidification.
- the matrix material of the polyhydroxyether melt adhesive remains mechanically stable and only during the curing of the matrix material it dissolves in this and cross-linked with the matrix material to form a homogeneous matrix.
- the fiber material according to the invention can be used particularly well together with reinforcing fibers of glass, carbon, aramid, polybenzoxazole, polybenzimidazole and / or other, so-called "rigid rod” polymers as well as matrix materials of a crosslinkable resin system such as epoxy resin, unsaturated polyester resin, isocyanate ester resin, phenolic resin, Formaldehyde-phenolic resin, melamine resin or a combination of these resins.
- a crosslinkable resin system such as epoxy resin, unsaturated polyester resin, isocyanate ester resin, phenolic resin, Formaldehyde-phenolic resin, melamine resin or a combination of these resins.
- the matrix could also consist entirely of polyhydroxyether.
- the temperature should be higher than the glass transition temperature Tg of the polyhydroxyether used in the fiber material according to the invention, so that according to the invention the fiber material dissolves in the matrix and crosslinks with it.
- the polyhydroxyether fiber material according to the invention is preferably produced by melt spinning. Especially preferred is a spin-draw process.
- the raw material used was a commercially available polyhydroxyether, as sold, for example, by InChem under the name InChemRez® PKHH phenoxy resin, having a molecular weight Mw of 52,000 daltons. Its glass transition temperature Tg (DSC) was 92 ° C. The use of higher or lower molecular weight InChemRez® grade or the use of a similar raw material from another manufacturer would also be possible.
- the polyhydroxyether polymer was fed in the form of pellets to the spinning machine. If necessary, heat and UV stabilizers or other additives in this phase can still be added via a volumetric or preferably via a gravimetric dosing unit.
- the pellets were previously dried to a residual moisture of less than 0.01% H 2 O to prevent formation of water vapor bubbles in the melt. In the spun filaments such bubbles lead to defects, which can lead to tearing even at the lowest mechanical stress.
- a vacuum tumble dryer was used for drying. It was dried for 15 hours at 80 ° C.
- the residence time should therefore be less than 15 minutes.
- the residence time is less than 10 minutes and more preferably even less than 8 minutes.
- the spinning machine and the spinning parameters were suitably designed, i.a. by using only one extruder per spinneret and thus a relatively short melt line and a volume-optimized spinneret.
- the extruder and spinning head temperature should be adapted to the melt viscosity, respectively to the molecular weight of the polymer, so that the material is sufficiently ductile and no brittle fractures occur immediately after the spinning head, where the spinning distortion is high.
- InChemRez®-PKHH these are about 100 ° above its initial flow temperature, that is to say at 240 to 300 ° C., preferably at 260 to 280 ° C.
- the nozzle plate had capillaries with a diameter of 0.5 mm, with diameters of 0.35 to 0.80 mm would also be possible. This resulted in a nozzle pressure of about 50 to 100 bar, which guaranteed a uniform distribution of the melt on all capillaries (nozzle hole bores).
- the nozzle plate was provided with a diameter of 180 mm with only 40 capillaries.
- the capillary density was thus smaller than 0.25 holes / cm 2 . It was thus also about 10 times smaller than in melt spinning for example of polyester or polyamide usual.
- the mutual spacing of the individual filaments emerging from the capillaries was conversely comparatively large and the thread curtain formed by the individual filaments comparatively particularly well permeable. This enabled optimum passage of the blast air flow and thus a very effective cooling of the individual filaments.
- the blast air consumption was 200 - 300 m 3 / kg.
- the blowing air was additionally pre-cooled to approx. 16 ° C. As mentioned, was blown in the cross flow. Central blowing would also be possible and possibly even preferable.
- the convergence length between the nozzle plate and a preparation device before the first godet duo was about 5 m and was thus much larger than those used in melt spinning the usual fiber polymers.
- the individual filaments had relatively much time for cooling and loss of stickiness.
- the Galettenduos were heated to fix the multifilament yarn formed from the individual filaments after stretching at temperatures between 80 and 120 ° C.
- the fixation could be further improved and disturbing shrinkage in further processing can be largely prevented.
- the polyhydroxyether multifilament yarn thus prepared had the following properties: titres tex 50 Number of individual filaments f 40 Tensile strength N 5.5 tensile strength CN / tex 11 elongation at break % 41 rice energy N cm 102 Glass transition temperature ° C 93
- Example 2 The same spinning system was used as in Example 1 and the same procedure was followed.
- the lower melt viscosity allowed reduced spinning temperatures of 200 to 220 ° C at which the material under the spinneret was still sufficiently ductile. At this lower temperature level, gas bubble formation in the melt could be avoided. Thus, no intensive blowing of the filaments was necessary.
- the lower extrusion temperature required milder cooling conditions to keep the fresh filament stretchable, so the cooling air flow was reduced to 10-50m 3 / kg.
- the take-off speed was 1500 m / min and only one final stretch could be set by a factor of 1.1 - 1.2.
- the filaments were air-swirled with a Heberlein Polyjet SP25 for better thread closure.
- the produced polyhydroxyether multifilament yarn had the following properties: titres tex 50 Number of individual filaments f 28 Tensile strength N 4.7 tensile strength CN / tex 9.4 elongation at break % 38 Glass transition temperature ° C 85
- Example 1 Due to the lower molecular weight than in Example 1, the yarn had a slightly lower tensile strength, but the spinning process was more stable and the yarn showed hardly any broken individual filaments.
- Example 1 On a pilot staple fiber line developed and built by EMS-CHEMIE, 10 bobbins of Example 1 were pulled off parallel with this polyhydroxyether multifilament yarn and plied, air-textured and cut into staple fibers with a staple length of 80 mm.
- the application properties of the polyhydroxyether fiber material were determined by tests as follows:
- the cross-linking was checked by an extraction test.
- 10% short cut polyhydroxyether fibers in epoxy (Araldite® PY306 from Huntsman, Araldite® MY0510 from Huntsman, EPICURE TM 3601 from Resolution Performance Products) were dissolved and cured.
- the cast plate was milled with dry ice cooling and particles less than 60 microns were deposited.
- a plate without polyhydroxyether fibers and one with 10% polyester fibers (GRILENE® F3 6.7dtex) was prepared and prepared in the same manner.
- the powder fractions> 60 microns were extracted in m-cresol (Merck) for 2 hours at 95 ° C with stirring.
- the polyhydroxyether fiber material had completely dissolved under these conditions.
- the mechanical properties were tested on carbon fiber - epoxy composite panels.
- a 1200 mm wide UD fabric was produced with a T-700S 6K carbon fiber from Toray. In the shot everyone was 10 mm for fixation a polyhydroxyether multifilament yarn 500 dtex f40 woven.
- a sample was used with a commercially available Trevira® filament yarn (330 dtex), ie a finer thread, which should be less disturbing due to the thinner cross-section.
- the bending strength of the sample plate with polyhydroxyether fiber material according to the invention could be improved by 12% compared to the reference plate with polyester filament.
