Natural fibre reinforced polymer (NFRP) composites are emerging as a viable alternative to metal parts for lightweight components in the automotive and aerospace industry. They are economical and eco-friendly, but their use is confined due to their performance properties. Currently, fillers are often incorporated in NFRP composites to modify their properties. This study explores the reinforcing effects of hollow glass microspheres (HGM) as fillers in continuous NFRP composites. Continuous NFRP laminates were fabricated using woven fabrics (jute, hemp, flax, polypropylene) and HGM with compression moulding. Tensile, flexural and impact tests were conducted to investigate the influence of HGM on the mechanical properties of these laminates. The results indicate that the loading of 1.5 % HGM improves the tensile and flexural properties, but further addition of HGM (3 %) leads to a decline in these properties; furthermore, the impact strength was significantly improved (17 %, 8 %, 24 %) in jute, hemp and flax laminates, respectively by the addition of 3 % HGM.

天然纤维增强聚合物（NFRP）复合材料正在成为汽车和航空航天行业中轻质部件的金属零件的可行替代品。它们既经济又环保，但是由于其性能，它们的使用受到限制。当前，通常将填料掺入NFRP复合材料中以改变其性能。这项研究探讨了中空玻璃微球（HGM）作为连续NFRP复合材料中填料的增强作用。连续NFRP层压板是使用机织织物（黄麻，大麻，亚麻，聚丙烯）和HGM压模制成的。进行拉伸，挠曲和冲击试验以研究HGM对这些层压材料的机械性能的影响。结果表明，加入1.5％HGM可以改善拉伸和弯曲性能，但进一步添加HGM（3％）会导致这些性能下降；此外，通过添加3％的HGM，黄麻，大麻和亚麻层压板的冲击强度显着提高（分别为17％，8％，24％）。
