Definitions

  • the invention relates to a rollable textile nonwoven sheet product, consisting of a mixture of recycled carbon fibers and thermoplastic fibers, which are laid into a fiber pile by means of a carding process, subjected to a fleece formation and then thermally bonded, according to the preamble of claim 1.
  • the fiber composite material has fibers and at least one thermoplastic matrix material.
  • the aforementioned fibers are isolated from fiber-containing waste or old parts and mixed with thermoplastic fibers and laid flat in a carding process so that a fiber pile is produced.
  • a plate material is formed under the action of heat in the form of a pressing step.
  • carbon fibers that are available at low cost can be used as reinforcing fibers.
  • carbon fibers, carbon fiber bundles or their mixtures are isolated from carbon fiber-containing waste or old parts and these are mixed with thermoplastic foreign fibers.
  • flat laying down and alignment takes place in such a way that a fiber web is created with a targeted orientation of the fibers in the longitudinal direction.
  • the already mentioned pressing is then carried out under the action of heat to form a plate material.
  • FIG WO 2011 / 101094A1 proposed adding foreign textile fibers, such as polypropylene, to increase the degree of fiber orientation of the carbon fibers as well.
  • Auxiliary fibers are used to specifically influence the degree of fiber orientation of carbon fibers.
  • the oriented carbon fibers are brought into an adhesive state through the proportion of thermoplastic fibers with subsequent compression and compression to form sheet goods and finally cooling.
  • pressing takes place at a pressure of 400 N / cm 2 , in the sense of compacting.
  • thermoplastic component used being a fibrous material made from polyhydroxyether.
  • the EP 1 772 258 B1 discloses a laminate structure of a plastic part with coarse fibers of ⁇ 10 dtex.
  • the composite material consists of aligned reinforcing fibers embedded in a thermoplastic matrix, a scrim made from the aligned reinforcing fibers and thermoplastic material and the thermoplastic material being heated to a temperature above its melting point.
  • reinforcing fibers carbon fibers come into consideration.
  • the EP 2,886,693 discloses a rollable textile nonwoven sheet product consisting of a mixture of recycled carbon fibers and thermoplastic fibers, which is laid into a fiber web by means of a carding process, subjected to a nonwoven formation and then thermally bonded.
  • the object of the invention to provide a further developed rollable, i.e. Rollable or windable textile nonwoven sheet product, consisting of a mixture of recycled carbon fibers and thermoplastic fibers, to indicate which has an open-pore nonwoven structure, so that a later further treatment, e.g. Impregnation with a resin is possible in a simple manner.
  • the nonwoven sheet product to be created should retain the carbon fibers used in their original consistency, i.e.
  • One of the main goals is to keep the carbon fiber content as high as possible, but also to ensure the mentioned impregnation properties and to minimize the generation of dust from unbound fiber pieces.
  • a rollable and therefore easy to handle textile nonwoven sheet product which consists of a mixture of recycled carbon fibers and thermoplastic fibers. This mixture is laid into a fiber web by means of a carding process, subjected to a fleece formation and then thermally bonded, specifically in the sense of a pre-consolidation.
  • thermoplastic fibers in the mixture is in the range from 5% by weight to 40% by weight and the proportion of carbon fibers in the range between 60% by weight and 95% by weight, the thermal bonding to avoid carbon fiber damage under low pressure of ⁇ 20 N / cm 2 takes place in such a way that the desired open-pored, impregnable fleece structure is retained.
  • the fiber fineness of the carbon fibers used is in the range ⁇ 1 dtex.
  • the cut length of the carbon fibers is in the range between 30 mm and 80 mm.
  • the fiber fineness of the thermoplastic fibers is in the range between 1.0 and 4.0 dtex.
  • the cut length of the thermoplastic fibers is in the range between 30 mm and 70 mm.
  • the fiber mixture is subjected to a solidification by increasing the temperature in the range up to 200 ° C and subsequent cooling, whereby a melting of the thermoplastic fibers is prevented, but the fibers are melted to connect with the carbon fibers.
  • the nonwoven sheet product obtained has an open-pored, good impregnation property, but also a very uniform, high-quality surface.
  • the carbon fibers are not damaged or only slightly damaged by the measures according to the invention during the solidification process, so that there is no reduction in strength in the later composite material and disadvantageous dust generation from unbound fiber pieces.
  • the fiber web is produced using a carding process.
  • the proportion of carbon fibers is chosen as high as possible, since the added proportion of thermoplastics is a foreign component.
  • a bicomponent fiber one of the components has a lower melting point than the other, second component.
  • the recycled carbon fibers used can be, for example, cut roving residues, pre-dissolved scraps of scrim or fabric, edge sections, Fibers that come from carbon fiber-reinforced plastics and have been recovered there by means of thermal, chemical or other processing.
  • a hot calender, a smoothing unit, a belt calender, a shirt collar press, a belt press or a hot ironer are used as the consolidation unit, whereby a modification is made such that the pressure applied is in the range ⁇ 2 bar, i.e. ⁇ 20 N / cm 2 , to avoid fiber damage definitely to avoid.
  • the resulting goods are wound up gently and with little tension by means of an ascending batch winder.
  • the weight of the nonwoven fabric obtained is in the range from 50 to 200 g / m 2 , preferably in the range between 80 to 150 g / m 2 .
  • the strength properties of the nonwoven sheet product are low compared to the weight per unit area, but far more than sufficient to ensure both the desired winding and positive handling during subsequent processing.
  • further components of high-performance fibers from recycling processes can be mixed in in addition to the carbon fiber content.
  • This can be, for example, aramid fibers, glass fibers, basalt fibers or the like.
  • care must be taken to ensure that the proportion of thermoplastic fibers of 5% by weight to a maximum of 40% by weight is maintained and not exceeded.
  • the material can be wet-finished with chemical substances, with these substances then reacting out by means of a drying and fixing process.
  • the nonwoven sheet product can be pre-impregnated with resin to obtain a prepreg.
  • nonwoven sheet product Possible application examples for the use of the nonwoven sheet product are applications in the automotive sector, in particular the interior, the visible side cover of a hood of a motor vehicle, but also the use as a sandwich structure, as a filler or as the top of rotor blades in wind turbines.
  • a fiber mixture of 90% edge cut from a multiaxial fabric production and 10% bicomponent fibers based on polyester are mixed. This mixture is laid into a fleece using the carding process and cross-layer. The fleece is then consolidated under minimal pressure and at a temperature of ⁇ 200 ° C.
  • the nonwoven fabric obtained has a strength in the longitudinal direction of> 1.7 N / cm 2 , specifically with a weight per unit area of 150 g / m 2 .
  • the nonwoven fabric obtained in this way serves as fiber reinforcement for a polyester resin matrix, which is then shaped into a plate and has a 1A surface quality.
  • thermoplastic fibers are not melted or liquefied in their entirety, but only melted on in order to effect a connection or gluing with the carbon fibers.
  • the low application of pressure in the range 20 20 N / cm 2 does not lead to undesired compression of the material, but merely serves to smooth the surface of the material and to support the connection between the thermoplastic fibers and the carbon fibers. This treatment almost eliminates fiber damage.
  • the pile layer made from the fiber mixture using the carding process can be paneled in accordance with possibly desired higher grammages.
  • the fibers are glued together at temperatures of up to 200 ° C.
  • the nonwoven fabric according to the invention can be used as a flat product or as a reinforcement material for other composite materials, but can also be used as an intermediate layer or for structural reinforcement in areas where no high tensile forces are required. Due to the lack of structuring and the high fiber resolution, class A surface properties are achieved. Since there is no pressure-relevant mechanical fastening, the resulting nonwoven is an alternative to wet-bonded nonwovens.
