在这项研究中，混合纱线的开发通过混合的连续聚丙烯和玻璃纤维使用空气喷射和直接捻制备技术。从这些混合纱线获得具有± 45 °纤维取向的无卷曲织物。采用与聚丙烯基体相容和不相容的纤维浆料制备织物，以研究界面粘合对热塑性复合材料性能的影响。采用热压工艺制备了复合材料板材，并对复合材料的微观结构和力学性能进行了研究。结果表明，混纤纱的制备工艺和玻璃纤维上浆对复合材料的性能有重要影响。由喷气混合纱制备技术生产的织物制成的复合材料表现出比直接加捻包覆（单或双）混合纱制备技术生产的复合材料更好的结果。最高的弯曲性能（99.1 MPa的弯曲强度和9.55 GPa的弯曲模量），从织物含有兼容的上浆，由于更好的粘合在玻璃纤维和聚丙烯基体的界面处制造的复合材料。由具有聚丙烯相容胶料的织物制成的复合材料也表现出最高的抗剥离性（层间剥离强度值为5.87N/mm）。另一方面，研究发现，混杂纱制备工艺和玻璃纤维浆料的类型对玻璃纤维/聚丙烯复合材料的冲击性能的影响不显著。
In this study, hybrid yarns were developed by commingling the continuous polypropylene and glass fibers using air jet and direct twist preparation techniques. The non-crimp fabrics were obtained with ± 45 ° fiber orientation from these hybrid yarns. The fabrics were prepared with fiber sizings that are compatible and incompatible with polypropylene matrix to investigate the effect of interfacial adhesion on the properties of the thermoplastic composites. Composite panels were produced from the developed fabrics by hot press compression method and microstructural and mechanical properties of the composites were investigated. It was found that type of the hybrid yarn preparation technique and glass fiber sizing applied on the glass fibers have some important role on the properties of the composites. Composites made of fabrics produced by air jet hybrid yarn preparation technique exhibited better results than those produced by direct twist covering (single or double) hybrid yarn preparation techniques. The highest flexural properties (99.1 MPa flexural strength and 9.55 GPa flexural modulus) were obtained from the composites manufactured from fabric containing compatible sizing, due to better adhesion at the interface of glass fibers and polypropylene matrix. The composite fabricated from fabric with polypropylene compatible sizing also exhibited the highest peel resistance (interlaminar peel strength value of 5.87 N/mm). On the other hand, it was found that hybrid yarn preparation technique and type of the glass fiber sizing have insignificant effect on the impact properties of the glass fiber/polypropylene composites.
