Definitions

  • the invention relates to a roll cover made of a fiber composite material.
  • Roll coverings made of fiber composite materials are used in web-processing machines in a variety of ways. The most demanding requirements are placed on elastic calendar covers with regard to compressive stress and dynamic stress on paper machines. These covers are usually constructed of fiber composite material.
  • Roll covers are known with varying fiber content in the matrix component.
  • the BP 0 487 447 A1 further discloses a roll cover with wear reducing filler in the matrix material.
  • the so-called filament winding method in which fiber bundles are wound onto a roll body and then joined together by means of resins to form a fiber composite material.
  • the disadvantage is that the finished roll cover is made up of different layers.
  • the interface between different layers is often here, due to the sudden change in material properties, the starting point for Delaminationserscheinonne in roll cover.
  • the second application method is not suitable, for example, for the production of wear layers to be brought into contact with the paper web in straighteners, since such roll shells lead to an uneven smoothing of the paper web, since the wound fibers are substantially rectified.
  • roller covers produced by the filament winding method are additionally provided with one or more laminated layers, which takes over the function of the wear layer.
  • roller covers are created here, which are composed of several underschildlichten layers.
  • the present invention provides a fiber composite roll cover made of a material having a fibrous component and having a matrix component comprising the fibrous component material composition and a matrix component
  • the matrix component changes quantitatively and qualitatively at least in sections continuously and in which a wear-reducing type of filler is used, which is formed by a carbide or oxide and has a particle size in the nanometer range.
  • a matrix component is to be understood as meaning the material or the material composition in which other dissolved or undissolved materials are embedded.
  • the fiber component is embedded in the matrix component.
  • the invention thus provides, at least in sections, a roll cover without boundary layers, since the material composition of the roll cover changes continuously in sections.
  • a roll cover which has a continuous course of characteristic properties such as, for example, Young's modulus, fracture toughness, abrasion resistance or hardness.
  • the Materialzusarnrrmen GmbH of fiber component and matrix component and filler component changes at least in sections continuously.
  • a roll cover At a roll cover a variety of requirements are made. For example, it is often necessary that a roll cover is dimensionally stable and at the same time has a high wear resistance.
  • the dimensional stability is realized here by the radially inward areas.
  • the wear resistance is realized by the radially outward areas.
  • a preferred embodiment of the invention therefore provides that the material composition in the axial direction and / or in the radial direction of the roll cover changes continuously at least in sections.
  • the material composition of the roll cover material can change continuously.
  • the proportion of the material composition of at least one of the components changes, namely the fiber component and / or the matrix component and / or the filler component.
  • the proportion of the fiber component in the radial direction it is possible for the proportion of the fiber component in the radial direction to be reduced from 30% to 5% to the outside, whereas the proportion of the matrix component increases correspondingly while the proportion of the filler component remains the same.
  • composition of one or more of the components changes.
  • the fiber component is preferably formed by one or more fiber types.
  • a change in the composition of the fiber component should be understood to mean that the proportion and / or the diameter and / or the length distribution and / or the orientation of the fibers of at least one fiber type change.
  • a desired property profile of the roll cover can be adjusted depending on the location.
  • the stability can be influenced location-dependent.
  • the tensile strength is strongly dependent on the orientation of the fibers.
  • the matrix component preferably comprises one or more resin types and one or more types of curing agents.
  • a change in the composition of the matrix component should be understood to mean that the mixing ratio of at least one type of resin and / or at least one hardener component in the matrix component changes.
  • the mixing ratio of at least one type of resin changes while maintaining the hardness in the radial direction of the roll cover in which the proportion of epoxy resin from the inside of the roll cover towards the outside (paper side) of the roll cover from 100% to 0% continuously decreases whereas the proportion of polyurethane resin inversely increases from 0% to 100% in the direction of the outside of the roll cover from the inside of the roll cover.
  • a roll cover is produced, which has a paper-side wear layer of polyurethane resin and a base layer of epoxy resin, wherein the two layers merge continuously in the radial direction.
  • the filler component is preferably formed by one or more types of fillers.
  • a change in the composition of the filler component should be understood to mean that the proportion and / or the grain size of at least one filler type changes.
  • Preferred fiber types include inorganic fibers of glass, metal, ceramic fibers, boron or organic fibers, for example carbon and / or aramid and / or polypropylene or polyester or high-performance thermoplastics such as, for example, PPS or PEEK or PTFE fibers.
  • the fiber component consists of only one type of fiber
  • the proportion of one fiber type for example glass fibers
  • the proportion of the fiber component in the material composition can be changed continuously in the radial direction.
  • a preferred embodiment of the invention provides that at least one fiber type is formed by fiber pieces with a defined length distribution, which are not connected to one another before being embedded in the matrix component.
  • Fiber pieces should be understood in this context that the fibers are not formed as fiber bundles (in contrast to filament winding process) or as fiber mats (in contrast to the lamination process). Rather, pieces of fiber having a defined length distribution prior to embedding in the matrix component are discrete, i.e., loose. unconnected fiber pieces.
  • a preferred embodiment of the invention provides that at least one type of fiber comprises a portion of fiber pieces embedded in an undirected orientation in the matrix component.
