  text: 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.
