Definitions
- the invention relates to a flat semifinished product, a Ver ⁇ drive for the production of sheet semi-finished products and the use of a sheet semi-finished product according to the preambles of the independent claims.
- Fiber-reinforced plastics win for making constructive ⁇ tureller components increasingly important. Such components are particularly suitable for use in motorsport, aerospace, rail ⁇ nen poverty- and aircraft. For example, these construction ⁇ share the same performance a lower weight than conventional components made of steel, aluminum or wood on, leading to savings in energy - leads and fuel consumption.
- Fiber-reinforced plastics can be achieved, for example, by embedding fibers in a plastic matrix and then curing.
- the plastic matrix is dominated by thermosetting resin systems.
- the fibers and resin may be combined with suitable hardeners and stored in an uncured state.
- the crosslinking to a fiber-reinforced plastic then takes place only at a later time ⁇ point.
- epoxy resins are used as resins.
- these are storage-stable only for a limited time due to the presence of hardeners and accelerators in the resin matrix.
- such reactive systems are stored at low temperatures (about -20 ° C) and must be thawed before further processing.
- WO 2015/097097 A1 describes a storage-stable prepreg based on an epoxy resin which cures to a thermoset with a crosslinking agent.
- the storage stability is by a spatial separation of reactive resin and crosslinking agent after the drying achieved.
- the mixing of the components can then be carried out by increasing the temperature at which all components are melted.
- these latently reactive epoxy resins cause relatively long pressing times at relatively high temperatures during the processing of the prepregs. Longer pressing times and higher process temperatures would also affect the types of fibers that can be used. Low melting fiber types such as polyamide, polyethylene or polyester are not usable. In addition, only curing to duromers is possible.
- thermosets have the disadvantage that they lead to cracks and cracks in the material under high and instantaneous mechanical action and thus to a weakening of the material.
- WO 99/29755 describes a process for the preparation of storage-stable, latently reactive layers and powders of surface-deactivated, solid polyisocyanates and dispersions or aqueous solutions of isocyanate-reactive polymers, which can be used as adhesives and covers.
- WO 2013/139704 discloses storage-stable prepreg (pre-impregnated fibers) on the basis of low-viscosity polyurethane systems and articles made flat fiber composite components (moldings, composite components) obtained by means of an impregnation process for fibers-reinforced materials such as woven and nonwoven ⁇ the.

- Plastic composition to an elastomer, in particular to a thermoplastic elastomer, is curable
- the fibers are embedded in the matrix continuous fibers, wherein the fibers are preferably aligned unidirectionally.
- the fibers are enveloped by the matrix.
- the wrapping can be done for example by spraying with the matrix or by pulling the fibers through a matrix solution.
- the inventive semi-finished product has the advantage that the fibers impregnated completely, that is surrounded by the plastic matrix ⁇ are. Before further processing (ie shaping and curing), the semi-finished product can be stored at room temperature over a long period of time.
- the semi-finished product according to the invention is further distinguished by the fact that it is suitable for the production of fiber composite component with a high resistance to mechanical action.
- the resistance to mechanical action also results from the use of continuous fibers. Such fibers increase the stiffness and strength of the composite.
- continuous fibers are all fibers having a length of 50 mm.
- the fibers are unidirectionally aligned.
- unidirectional means that the longitudinal axes of the individual fibers are substantially parallel, and “substantially parallel” means that the
- Longitudinal axes of the fibers do not enclose angles of more than ⁇ 25 ° with each other. Preferably, the angles between the longitudinal axes of the fibers are less than ⁇ 10 °.
- Unidirectional semi-finished products have the advantage that they can be stacked along the course of force. If several planar semi-finished products, each with unidirectional fibers aligned twisted to each other, resulting in a particularly high resistance to ⁇ over mechanical influences from different sides.
- the fibers can be based on proteins, cellulose, synthetic polyme ⁇ ren or inorganic substances.
- Protein-based fibers can be selected from the group: wool, silk, angora, cashmere, casein, collagen, ardine and zein.
- Cellulosic fibers may be cotton and bast fibers such as cotton, linen, hemp or jute. Cellulosic fibers may also be wood-based such as Viscose, Modal, Lyocell, Cupro, acetate.
- Fibers of synthetic polymers may be selected from the group: polyethylene, polyester; Polyamide; aramid; Polypropylenes; Polyurethane (elastane); Acrylic; polytetrafluoroethylene; Polyphenylene-2, 6-benzobisoxazole; Liquid crystal polymers (LCP), in particular ⁇ poly (p-hydroxybenzoic acid-co-hydroxy-6-naphthoic acid.
- the group of fibers of inorganic substances include carbon, ceramics, glass, quartz, metal.
- the fibers may be embedded as single fibers in the matrix or previously spun into a thread and embedded as a thread. Likewise, the fibers may have been processed into threads and then into a fabric, thereby embedding the fabric. It is possible to embed ⁇ also filaments. Where among filaments artificial, arbitrarily long fibers to be understood. It is also conceivable that a combination of different fibers is embedded.
- the plastic composition comprises a polyurethane and a latently reactive isocyanate.
- the isocyanate is preferably encapsulated or surface-deactivated or blocked.
- a radiation-crosslinkable isocyanate would also be conceivable.
- the amount Behaves ⁇ nisse between polyurethane and isocyanate may vary.
- the following compositions for surface-deactivated isocyanates are conceivable: At 100 parts by weight (pbw) of polyurethane, 5 to 10 pbw of toluene-2,4-diisocyanate dimer (TDI dimer) can be added.
- IPDI trimer isophorone diisocyanate trimer
- HDI trimer hexamethylene-4,6-diisocyanate trimer
- the latent-reactive isocyanate takes place at room temperature- no reaction between the isocyanate and the free OH groups of the polyurethane.
- the sheet-like semi-finished product can be stored at room temperature ⁇ for a long time without any hassle.
- the reaction process ie the reaction with a surface-deactivated isocyanate, can be carried out by briefly starting the reactions at low temperatures ( ⁇ 120 ° C). But it can be used, which until hö ⁇ higher temperatures, for example at temperatures above 120 ° blocked isocyanates can be activated.
- the molding process eg pressing, vacuum bag process or autoclave

- the plastic composition may also be present as a powder or melt.
- the application of the dispersion can be carried out, for example, by spraying, knife coating, impregnation, infusion and / or vacuum infusion.
- the fibers can also be pulled through the dispersion solution and thereby spread.
- the dispersion promotes fiber spreading. As a result, the degree of wetting can be increased, which leads to optimum fiber incorporation and a high fiber content in the matrix.
- the plastic composition is essentially free of VOC (volatile organic compounds). This increases occupational safety when dealing with the plastic composition.
- terer functional additives such as flame retardants, agents with antimicrobial activity, adhesion promoters eg to increase the affinity for metals or to increase the affinity to rubber or similar materials, fluorescence agents or UV protection agents, have further properties.
- the fibers are arranged substantially in longitudinal extension to a main surface of the semi-finished product.
- Unidirectional semi-finished products have the advantage that they can be stacked along the course of force. After further processing (pressing, curing), a robust and resistant fiber composite component can thus be obtained.

- the matrix has at least one latently reactive plastic composition, which is curable to form an elastomer, in particular a thermoplastic elastomer.
- the semi-finished product produced in this way can be mounted at room temperature ⁇ over a long period.
- latent-reactive, encapsulated, surface-deactivated or blocked isocyanate makes it possible to activate only at high temperatures. This is in contrast to two-component systems whose reactivity depends on the activation state of a catalyst.
- Such Sys ⁇ tems are typically re ⁇ already active at temperatures below 100 ° C and can thus ER- short-lasting shelf life ranges are.
- the latent reactive plastic composition can be cured at temperatures in the range of 60 to 180 ° C, preferably 100 to 140 ° C.
- the curing can be done after shaping.
- the semi-finished product is optionally cut and placed in a mold ⁇ tool, such as a press.
- the curing can take place simultaneously.
- the reactivation temperatures can be low compared to conventional methods and thus also allow the use of low-melting fiber types. Subsequently, the fiber composite component can be removed from the mold and, if necessary, reworked.
- the fibers may for albumin, cellulose, synthetic polyme ⁇ ren or inorganic substances such as off already in the foregoing, based described in detail.
- a combination of different fibers in a semi-finished product is also conceivable. By choosing the fibers, the properties of the semi-finished product as well as of the fiber composite component can be controlled.
- the plastic composition preferably comprises polyurethane and a latent reactive isocyanate.
- the isocyanate can be verkap ⁇ selt, ober sunlightdes15ert or blocked.
- Latent reactive isocyanates remain unreactive at room temperature for a long time. As a result, semi-finished products produced in this way can be stored for months and without any effort before further processing. Reactivation may be at lower temperatures compared to conventional processes. Process times and energy input can be reduced.
- such a plastic composition results in an elastomer, in particular a thermoplastic elastomer, with soft and hard segments.
- the resulting fiber composite member exhibits high end properties such as cohesion, tensile strength, toughness, fatigue, aging.
- the component is essentially stress-free compared to other fiber composites.
