Influence of stacking sequence on mechanical properties of areca-kenaf fiber- reinforced polymer hybrid composite

ABSTRACT

Hybrid laminates made using natural fibers have been finding applications in diverse fields such as automotive parts, building structures and sports goods. These laminates incorporate the benefits of the reinforcements used in constructions. The present work deals with the fabrication of hybrid laminate comprising of the natural fibers areca and kenaf in varying stacking sequences through the hand layup method. Epoxy resin (LY556) and hardener (HY951) are mixed in the ratio of 10:1 to prepare the matrix material. Six different hybrid laminates having five layers of areca and kenaf in different stacking sequences are produced. Two more laminates having either kenaf or areca in all the five layers and are produced to act as reference laminate. The prepared laminates are cut as per ASTM standards and subjected to tensile, compressive, flexural, impact and hardness tests in order to identify the properties of the fabricated laminates. The result shows that composite made with kenaf fiber as skin material and areca as core materials exhibit better tensile, flexural and hardness properties. Likewise, composites with outer layers of areca and core layers of kenaf fibers have high compressive and impact strength. The fractured surfaces after the mechanical tests are investigated through the Scanning Electron Microscope (SEM).

摘要

由天然纤维制成的复合材料层合板在汽车零部件、建筑结构和体育用品等多个领域得到了广泛的应用. 这些层合板结合了建筑加固材料的优点. 本文研究了用手工铺层法，将天然纤维槟榔果和红麻按不同的铺层顺序叠合而成的混合层压板. 环氧树脂(LY556)与固化剂(HY951)按10:1的比例混合制备基体材料. 生产了5层槟榔叶和红麻的6种不同叠层复合材料. 另外两个层板在所有五层中都含有红麻或槟榔果，作为参考层板. 制备的层压板按照ASTM标准进行切割，并进行拉伸、压缩、弯曲、冲击和硬度测试，以确定所制备的层压板的性能. 结果表明，以红麻纤维为表层材料，槟榔果为芯材的复合材料具有较好的拉伸、弯曲和硬度性能. 具有槟榔芯层和红麻纤维芯层的复合材料具有较高的抗压强度和抗冲击强度. 利用扫描电子显微镜(SEM)对断裂后的断口进行了力学分析.
