  text: "Woven fibre-reinforced polymers are used in a variety of application, especially
    where a low mass to stiffness ratio is required. Of paramount importance for the
    tailored mechanical properties these composite materials exhibit is the type and
    geometry of the fibre weave. Especially continuous fibre-reinforced thermoplastic
    composites are fabricated as laminates and subsequently exposed to forming processes
    which alter the geometry of the fibres unit cell and thus the local mechanical
    properties of the material. An approach utilising broadband ultrasonic waves is
    proposed to non-destructively determine the geometry of the unit cell of the weave.\r\n\r\nThe
    dispersive behaviour of woven fibre-reinforced sheets is described in accordance
    with the Flouquet-Bloch theorem as a phononic crystal. In order to develop a model
    for a description of these periodically structured waveguides, the smallest repeating
    unit of the wave is modelled with periodic boundary conditions. The resulting
    dispersion diagram exhibits similarities to that of a homogeneous plate, but additionally
    displays a periodicity in the wavenumber regime, which correspond with the size
    of the unit cell. Experimental studies of the dispersive behaviour of acoustic
    waves in woven fibre-reinforced samples also show a periodicity in the wavenumber
    regime, enabling a measurement procedure of the unit cell geometry."

  text: <jats:p> Microcellular wood fiber reinforced polymers offer the possibility
    to reduce the use of fossil raw materials. In particular, thick-walled structures
    with thicknesses greater than 6 mm offer a high potential for weight savings.
    This study investigates the cell structures and mechanical properties of injection-molded
    test specimens. The influence of different thicknesses (6–10 mm) along with different
    chemical blowing agents (endothermic, exothermic) with varying dosages (0–2 wt%)
    is analyzed. The investigations reveal that exothermic chemical blowing agents
    form finer cells consistently to thin-walled structures than endothermic ones.
    Higher foaming agent content leads to higher pore fractions, with many small cells
    coalescing into a large open-pore cell network. The mechanical properties depend
    mainly on the pore content of the sample. The specific tensile properties deteriorate
    with the use of chemical blowing agents (CFA), whereas the sandwich structure
    produced with compact edge layers has a positive influence on the specific flexural
    properties. </jats:p>

  text: <jats:p>Wood–plastic composites (WPC) are enjoying a steady increase in popularity.
    In addition to the extrusion of decking boards, the material is also used increasingly
    in injection molding. Depending on the formulation, geometry and process parameters,
    WPC tends to exhibit irregular filling behavior, similar to the processing of
    thermosets. In this work, the influence of matrix material and wood fiber content
    on the flow, mold filling and segregation behavior of WPC is analyzed. For this
    purpose, investigations were carried out on a flow spiral and a sheet cavity.
    WPC based on thermoplastic polyurethane (TPU) achieves significantly higher flow
    path lengths at a wood mass content of 30% than polypropylene (PP)-based WPC.
    The opposite behavior occurs at higher wood contents due to the different shear
    thinning behavior. Slightly decreased wood contents could be observed at the beginning
    of the flow path and greatly increased wood contents at the end of the flow path,
    compared to the starting material. When using the plate cavity, flow anomalies
    in the form of free jets occur as a function of the wood content, with TPU exhibiting
    the more critical behavior. The flow front is frayed, but in contrast to the flow
    spiral, no significant wood accumulation could be detected due to the shorter
    flow path lengths.</jats:p>
