Natural plant based fibres are being increasingly used in sustainable fibre reinforced composite applications in order to meet the demand of using environmentally friendly materials for composites. Fibre metal laminates (FMLs) are used in aerospace, automobile, marine and civil engineering applications, due to their excellent mechanical behaviors compared to traditional metals and their alloys. This study describes a novel fabrication of jute fibre reinforced aluminum metal laminates, using different jute fibre architectures (plain and twill fabric structures), wherein jute fibres were used in the skins and aluminum in the core layers. Jute fibres and aluminum sheets were chemically treated to enhance the compatibility and interfacial bonding at fibre-metals-matrix interfaces. FMLs were manufactured by hot pressing technique, after the application of wet lay-up process for the resin impregnation and they were further tested under tensile, flexural and impact loading conditions. While comparing results, the twill architecture showed improved tensile and flexural properties compared to plain fabric based FMLs. Chemical treatments on twill jute fibres and metal sheets further exceptionally enhanced the flexural properties (151 MPa flexural strength and 21.3 GPa modulus and they were increased by 186.5 % and 722.7 % respectively compared to the untreated jute fibre counterparts) of the laminates due to a significant improvement in the adhesion between the jute fibre and aluminum sheet after alkali treatment applied. Therefore, with these enhanced properties, jute based FML laminates can be used as sustainable composite materials in many structural applications.
为了满足对复合材料使用环保材料的需求，天然植物基纤维在可持续纤维增强复合材料应用中越来越多地被使用。纤维金属层压板（FML）由于其与传统金属及其合金相比具有优异的力学性能，被应用于航空航天、汽车、船舶和土木工程领域。本研究描述了一种新型黄麻纤维增强铝金属层压板的制造方法，使用了不同的黄麻纤维结构（平纹和斜纹织物结构），其中黄麻纤维用于表层，铝用于芯层。对黄麻纤维和铝板进行化学处理，以增强纤维-金属-基体界面处的相容性和界面结合力。在采用湿法铺层工艺进行树脂浸渍后，通过热压技术制造FML，并在拉伸、弯曲和冲击载荷条件下对其进行进一步测试。在比较结果时，与基于平纹织物的FML相比，斜纹结构显示出更好的拉伸和弯曲性能。对斜纹黄麻纤维和金属板的化学处理进一步显著提高了层压板的弯曲性能（弯曲强度为151MPa，模量为21.3GPa，与未处理的黄麻纤维对应物相比，分别提高了186.5%和722.7%），这是由于在进行碱处理后黄麻纤维与铝板之间的附着力有了显著改善。因此，凭借这些增强的性能，基于黄麻的FML层压板可在许多结构应用中用作可持续复合材料。
