Modification of Fibers

Spinning equipment for the melt spinning of glass fibers, simultaneous spinning of glass/polymer filaments (hybrid yarn)

  • Leibniz Application Laboratory
  • Spinning of E-glass, AR-glass and special glasses under industrial relevant conditions
  • hybrid yarns made of spinnable polymers PP, PLA, PBT, PA

Surface modification of reinforcing fibers by application of sizings and coatings

  • application during the spinning process and/or in a subsequent process by a foulard
  • Nanostructured surface modification for the enhancement of the mechanical fiber properties, the fiber-matrix adhesion and the chemical and thermal durability
  • development of multifunctional fiber surfaces by sizings and coatings containing nanoparticles (e.g. CNTs, graphene)

Interphase characterization

  • quasistatic and dynamic micromechanical investigation (single fiber pull out) of the fiber-matrix interphase in composites (micromechanical laboratory)
  • scanning electron/atomic force microscopical characterization of the fractured surfaces after micromechanical testing
  • investigation of the structure-property relationships: influence of interphases on the mechanical performance of composites (in cooperation with the Dept. Analytics/Dept. Mechanics and Composite Materials)
