This study presents the mechanical performance enhancements of jute fibre composites, manufactured from two newly developed novel jute fibre unidirectional (UD) preforms, namely, stitching-based and sizing-based examples. To increase the use of jute fibres, which are naturally abundant and inexpensive, and to provide research into the use of mechanically advantageous continuous unidirectional (UD) preforms in composites (which are still limited in use), this study employed polyvinyl alcohol (PVA) sizing and stitching techniques, thus increasing the abilities of jute fibres to withstand higher loads and enabling them to be used for lightweight structural applications. Alkali treatment was used on jute fibres in stitched and sized preforms, and bamboo slices were introduced to the jute preforms to further optimize the mechanical properties. The jute composites exhibited significant mechanical property enhancements, with maximum improvement observed in the case of the PVA-sized alkali-treated specimen, thanks to the excellent compatibility between the sized and alkali-treated jute fibres.
本研究展示了由两种新开发的新型黄麻纤维单向（UD）预制件制成的黄麻纤维复合材料的机械性能增强，即基于缝合和基于上浆的实例。为了增加天然丰富且价格低廉的黄麻纤维的使用，并为复合材料中机械性能优越的连续单向（UD）预制件的使用提供研究（其使用仍然有限），本研究采用了聚乙烯醇（PVA）上浆和缝合技术，从而提高了黄麻纤维承受更高载荷的能力，并使其能够用于轻质结构应用。对缝合和上浆预制件中的黄麻纤维进行了碱处理，并将竹片引入黄麻预制件以进一步优化机械性能。黄麻复合材料表现出显著的机械性能增强，在PVA上浆的碱处理试样中观察到最大的改善，这得益于上浆和碱处理的黄麻纤维之间的优异相容性。
