    2011-5-31 · The project “Hybrid Yarn Development” is focussed on commingled CF/PEEK hybrid yarnsparticularly for the production of failure tolerant high performance rotors for high temperatureapplicationsContinuous fiber reinforced composites with a thermoplastic matrix gains market importanceon the basis of numerous advantages regarding manufacturing and application. Compared tothermoset matrix composites they are characterized by higher toughness, failure tolerant ma-terial behavior, and the ability of being reshaped and repaired subsequent to manufacturing aswell as the unlimited storage time of the prepregs. Owing to a higher melt viscosity comparedto the thermoset plastics the impregnation of the textile reinforcement structure with the ther-moplastic matrix is significantly difficult. This can result in insufficient composite properties.It is extreme for the application of PEEK as a matrix material for example. In order to solvethis problem prior to consolidation, hybrid yarns …

    Fibers made of elements such as carbon, aramid and glass have higher mechanical properties than other conventional textile fibers and they enable the production of light weight composites as end products. Furthermore, commingling hybrid yarns generally have a characteristic feature so that their components are distributed homogeneously enough over the yarn cross section.

  • Manufacturing of Hybrid Yarn Thermoplastic Composites

    Abstract: Filament winding is a manufacturing method to produce composite materials with a thermosetting or thermoplastic matrix impregnated continuous fibers. Due to the high melt viscosity of thermoplastics, some problems such as inadequate fiber dispersion in the structure, low wetting ability, and interface quality problems between matrix and fiber might emerge.

    2015-12-15 · Scientists at Dresden Technical University have developed an extremely light three-dimensionally reinforced high-speed rotor made of carbon fibre reinforced plastic. The rotor is expected to find applications in centrifuges used in food-manufacturing or in the flywheels of vehicles. The developments at Dresden feature the use of commingled hybrid yarns (CF/PEEK hybrid yarn).
