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."}],"quality_controlled":"1","project":[{"name":"FaMOUS: Ein ultraschallbasiertes Messverfahren unter Berücksichtigung viskoelastischer Eigenschaften zur Charakterisierung der Faser-Matrix-Haftung bei Organoblechen sowie deren realitätsnahe Modellierung","grant_number":"495847374","_id":"157"}],"publication":"International Polymer Processing","citation":{"mla":"Moritzer, Elmar, et al. “Fiber-Matrix Adhesion in Glass Fiber Reinforced Thermoplastic Composite Laminates and Its Effect on Mechanical Properties.” <i>International Polymer Processing</i>, Walter de Gruyter GmbH, 2026, doi:<a href=\"https://doi.org/10.1515/ipp-2025-0077\">10.1515/ipp-2025-0077</a>.","bibtex":"@article{Moritzer_Brandes_Wittler_Claes_Wippermann_Haag_Gries_Henning_2026, title={Fiber-matrix adhesion in glass fiber reinforced thermoplastic composite laminates and its effect on mechanical properties}, DOI={<a href=\"https://doi.org/10.1515/ipp-2025-0077\">10.1515/ipp-2025-0077</a>}, journal={International Polymer Processing}, publisher={Walter de Gruyter GmbH}, author={Moritzer, Elmar and Brandes, Philipp and Wittler, Maurice and Claes, Leander and Wippermann, Mareen and Haag, Markus and Gries, Thomas and Henning, Bernd}, year={2026} }","ama":"Moritzer E, Brandes P, Wittler M, et al.
