Definitions

  • the present invention relates to a composite component, to the use of a composite component of the invention, to a wind turbine for a wind power installation, and to a method for producing a composite component.
  • Rotor blades for wind power installations have been known for some considerable time and are described for example in DE 10 2004 007 487 A1 and DE 10 319 246 A1. In their operation they are subject to high loads as a result of wind pressure, erosion, temperature fluctuations, UV radiation and also by precipitation. Particularly at locations with a tropical climate, distinguished by highly changeable weathering effects and a high atmospheric humidity, such as in Brazil or Taiwan, for example, but also in Germany, rotor blades tend to suffer erosion.
  • the rotor blades are to be extremely lightweight, in order to minimize the bending loads acting on any rotor blade hub present and also on the associated bearings and the tower of the wind power installation.
  • Rotor blades and rotor blade elements are customarily produced in a molding process in which fiber materials and/or core materials, especially balsa wood, are inserted into a rotor blade element mold and are treated with a hardening resin so as to form a potentially load-bearing composite material.
  • epoxy resins are frequently employed as resin. They are highly suitable for the construction of the base of a rotor blade or rotor blade element from fiber material and resin.
  • UHMW-PE ultrahigh molecular weight polyethylene
  • UHMW-PE is notable for very good wear resistances and abrasion resistances even in the face of abrasive media. Its abrasion resistance is six times higher than that of polyurethane.
  • UHMW-PE possesses excellent chemical resistance and also a low coefficient of friction, outstanding dimensional stability, and high impact strength even at low temperatures.
  • UHMW-PE is very difficult to bond using conventional adhesives and in particular does not adhere to resins, such as epoxy resins, for example.
  • the polyethylene foil is joined, by means of two rubber attachment layers, to an underlying base comprising a fiber material impregnated with curable resin.
  • a total of three curing or vulcanizing steps are needed in order to coat a rotor blade element.
  • the plastic composite component described in WO 2010/118860 consists of a thermosetting synthetic resin as outer layer, an elastomer layer, and a metal and/or plastic support layer. The layers are assembled in a single operation with heat treatment or under irradiation with UV light.
  • WO 2010/118860 also describes the use of the plastic composite component in rotor blades of helicopters or wind turbines.
  • a component more particularly a rotor blade, which is notable for very high wear resistance and abrasion resistance and at the same time requires little time and low temperatures in production.
  • a composite component ( 10 ) characterized by the following layer construction:
  • the layer ( 12 ) is disposed directly between the layer ( 11 ) and the layer ( 13 ),
  • the wording that the layer “consists” at least partly of a “polyurethane and an elastomer” or “includes at least” means that the material referred to is also a polyurethane elastomer.
  • the wording “polyurethane or elastomer” means that either a nonelastomeric polyurethane or an elastomer is meant that is not a urethane elastomer.
  • a preferred polyurethane in the present context is a thermoplastic polyurethane.
  • an advantageous feature of the design is that the laminate composite comprising the layers ( 11 ) and ( 12 ) is already fully cured and need not also be cured further by exposure to heat. In the design, therefore, the temperature needed for assembling can be kept lower than would be the case if the polyurethane layer ( 12 ) or the elastomer layer ( 12 ) likewise required curing. As a result, the significant advantage is achieved of simplification and acceleration of the assembly. In comparison to a layer construction in which the polyurethane layer ( 12 ) or the elastomer layer ( 12 ) is cured simultaneously with the layer ( 13 ) and where equal temperatures are employed for both curing procedures, the adhesion of the individual layers is increased.
  • the individual layers of the composite component ( 10 ), and therefore the composite component ( 10 ) as a whole, has better properties if the layers ( 11 ) and ( 12 ) have been joined in a first operation to form a laminate composite and the layer ( 13 ) have been joined in a second operation onto the laminate composite comprising the layers ( 11 ) and ( 12 ).
  • the polyethylene is a high molecular polyethylene (HMW-PE), an ultrahigh molecular polyethylene (UHMW-PE) or polytetrafluoroethylene (PTFE), preferably an ultrahigh molecular polyethylene (UHMW-PE).

  • UHMW-PE ultrahigh molecular polyethylene
  • PTFE polytetrafluoroethylene
  • the ultrahigh molecular polyethylene (UHMW-PE), in particular, is distinguished by very good wear resistances and abrasion resistances even in the face of abrasive media.
  • a layer ( 11 ) which consists at least partly of UHMW-PE, in the composite component it is possible to improve significantly the wear resistance and abrasion resistance of the composite component, more particularly of rotor blades.
  • a high molecular polyethylene (HMW-PE) for the purposes of the present invention is a high molecular polyethylene having an average molar mass of 500 to 1000 kg/mol.
  • An ultrahigh molecular polyethylene (UHMW-PE) in the context of the present invention is an ultrahigh molecular polyethylene having an average molar mass of more than 1000 kg/mol.
  • the UHMW-PE used has an average molar mass of between 1000 kg/mol to 10 000 kg/mol, more preferably an average molar mass of between 1000 kg/mol and 5000 kg/mol, especially preferably between 3000 kg/mol and 5000 kg/mol.

  • the polyethylene used may be a linear or a crosslinked polyethylene.
  • the ultrahigh molecular polyethylene used preferably has a density of 0.93 to 0.94 g/cm 3 .
  • the layer ( 11 ) further comprises a UV stabilizer which protects the polyethylene against aging caused by ultraviolet light.
  • Preferred UV stabilizers are organic and inorganic UV absorbers, selected more particularly from the list encompassing benzophenones, benzotriazoles, oxalanilides, phenyltriazines, carbon black, titanium dioxide, iron oxide pigments, and zinc oxide, or 2,2,6,6-tetramethylpiperidine derivatives such as bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate (“hindered amine light stabilizer (HALS)”).
  • HALS hinderetramethyl-4-piperidyl

  • UHMW-PE ultrahigh molecular polyethylene
  • a polyurethane in the context of this invention is a polyaddition product of at least dialcohols (diols) and/or polyols (e.g., long-chain diols) with polyisocyanates with formation of urethane groups (—NH—CO—O—).
  • the elastomer is an ethylene-propylene rubber (EPM), ethylene-propylene-diene rubber (EPDM), ethylene-acrylate rubber (EAM), fluorocarbon rubber (FKM), acrylate rubber (ACM) or acrylonitrile-butadiene rubber (NBR), preferably an ethylene-propylene-diene rubber (EPDM).
  • EPM ethylene-propylene rubber
  • EPDM ethylene-propylene-diene rubber
  • EAM ethylene-acrylate rubber
  • FKM fluorocarbon rubber
  • ACM acrylate rubber
  • NBR acrylonitrile-butadiene rubber
  • EPDM ethylene-propylene-diene rubber
  • polyurethanes and elastomers (especially those which are preferred) produce particularly effective bonding between the layer ( 11 ), which consists at least partly of polyethylene, and the layer ( 13 ).
  • polyurethane and also ethylene-propylene-diene rubber (EPDM) have particularly good adhesion properties when the polyethylene of the layer ( 11 ) is ultrahigh molecular polyethylene (UHMW-PE) and when the layer ( 13 ) is a at least partly of a plastic reinforced by fibers ( 14 ).
  • the polyurethane is a thermoplastic polyurethane.
  • thermoplastic polyurethane in the context of this invention is a polyurethane which within a particular temperature range can be (thermoplastically) reversibly deformed.
  • Thermoplastic polyurethanes are to be distinguished in particular from thermoset polyurethanes, which after they have cured can no longer be thermoplastically deformed.
  • the polyurethane is a polyurethane elastomer.
  • a polyurethane elastomer in the context of this invention is a polyurethane which is elastically deformable and preferably have a glass transition temperature (Tg) (determined by differential scanning calorimetry (DSC) with a heating rate of 10 K/min) of at most 20° C.
  • Tg glass transition temperature
  • the polyurethane elastomer has a glass transition temperature T g of between ⁇ 5° C. and ⁇ 45° C. (determined by differential scanning calorimetry (DSC) with a heating rate of 10 K/min).
  • the polyurethane elastomer has a Shore A hardness as per DIN ISO 7619-1 of at most 95, preferably of at most 85, more preferably of at most 75.
  • the polyurethane elastomer has a Shore A hardness as per DIN ISO 7619-1 of more than 40, preferably of more than 50, more preferably of more than 60.
  • the polyurethane elastomer has a Shore A hardness as per DIN ISO 7619-1 in the range from 40 to 95, preferably in the range from 50 to 85, more preferably in the range from 60 to 75.
