  text: "<jats:title>Abstract</jats:title>\r\n                  <jats:p>With the growing
    demand for lightweight solutions to reduce emissions, especially in the transportation,
    automotive and aerospace sectors, recyclable, continuous fiber-reinforced plastic
    composite laminates with a thermoplastic matrix are of rising interest. To achieve
    their maximum mechanical properties, the fiber-matrix adhesion (FMA) is critical.
    In this work, continuous fiber-reinforced thermoplastic laminates (CFRTPL) with
    a polypropylene (PP) matrix and twill woven glass fiber fabrics are produced by
    film stacking. The films used contain different amounts of maleic-anhydride-grafted
    PP (MA-g-PP) as a coupling agent to produce CFRTPL of different mechanical strengths.
    To analyze the FMA, the CFRTPL are subjected to Charpy-impact and tensile tests.
    Additionally, single fiber pull-out tests (SFPT) are conducted to further investigate
    the effect of MA-g-PP on the FMA. The results of the SFPT show an improvement
    in apparent interfacial shear strength (AIFSS) when the MA-g-PP content is increased,
    which can be attributed to an increase in FMA. However, the research shows that
    MA-g-PP has a low impact on the mechanical properties if the force is applied
    parallel to the warp and weft threads during tensile testing and the results of
    the Charpy-impact testing suffer from embrittlement of the matrix material. Subsequently,
    the results of this study are compared to three-point flexural tests conducted
    in a previous study. It can be concluded that tensile and impact tests are not
    suited to investigate FMA on a macroscopic scale, while SFPT and flexural tests
    provide a better alternative.</jats:p>"

  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."

    measurements can be used for material characterization, as the propagation time
    of sound waves and thus their velocity depends on the elastic material parameters.
    Measurement results for the elastic material parameters are acquired non-destructively
    using ultrasonic transmission measurements of hollow cylindrical polymer specimens.
    To determine the material parameters, an inverse approach is used comparing measurements
    with simulated data. Previous studies show that the procedure exhibits low sensitivity
    with respect to the shear parameters of the material. In order to increase the
    sensitivity, we propose to apply a spatially annular excitation on the base of
    the specimen. As a measure to analyse the sensitivities with respect to all parameters
    and their linear independence, we observe the volume of the parallelotope of the
    sensitivity vectors. Here, a scaled boundary finite element formulation of wave
    propagation in the specimen is expanded to yield derivative information directly,
    and a sensitivity analysis can be carried out efficiently. Finally, the results
    of this sensitivity analysis with regard to the annular excitation are also applied
    to the measurement setup.</jats:p>"

  text: The degree of crosslinking in unidirectional prepreg materials was investigated
    using differential scanning calorimetry to assess their curing behavior and thermal
    characteristics. To complement these measurements with a non-destructive, in-situ
    method, the propagation properties of guided acoustic waves in cured carbon fibre-reinforced
    epoxy plates were analysed. Correlations between the degree of crosslinking and
    acoustically determined mechanical properties were drawn to enable a future non-destructive
    evaluation approach.
