A selection of woven roving and woven filament yarn E-glass fabrics, equipped with different sizing and finish formulae, were tested for compatibility with maleic anhydride functionalised polypropylene (MAH-g-PP) matrices. Glass fibre-polypropylene laminates (GF-PP) were prepared at 50% fibre volume fraction via film stacking and flat panel compression moulding. The effectivity of the utilised coupling agent concentration on interfacial adhesion was characterised through indirect method in 3-point flexural tests. Besides aminosilane A-1100 and PP-compatible fabrics, FK144 Volan “A” chromium complex finished fabrics showed exceptional compatibility and performance in combination with MAH-g-PP modified PP matrices, which has not been reported in the literature before. Mean flexural properties of FK144 laminates peaked at 450 MPa for strength and 21 GPa for modulus at 0.10% MAH loading and a fibre volume fraction of 53%. Possible coupling mechanisms were discussed, which may explain the basic compatibility between the chromium complex and PP.

测试了选择的具有不同上浆和整理配方的机织粗纱和机织长丝电子玻璃织物与马来酸酐官能化聚丙烯（MAH-g-PP）基质的相容性。玻璃纤维-聚丙烯层压板（GF-PP）通过薄膜堆叠和平板压缩成型以50％的纤维体积分数制备。通过间接法在三点弯曲试验中表征了所用偶联剂浓度对界面粘附的影响。除氨基硅烷A-1100和与PP相容的织物外，FK144 Volan“ A”铬络合物完成的织物与MAH-g-PP改性的PP基体组合显示出优异的相容性和性能，这在以前的文献中未见报道。在0.10％MAH载荷和53％的纤维体积分数下，FK144层压板的平均弯曲性能在强度上达到450 MPa，在模量下达到21 GPa。讨论了可能的偶联机理，这可能解释了铬配合物与PP之间的基本相容性。
