Influence of Filler on Mechanical and Di-electric Properties of Coir and Luffa Cylindrica Fiber Reinforced Epoxy Hybrid Composites

ABSTRACT

Natural fiber hybrid composites were prepared by Hand layup technique by reinforcing coir, silk squash, and CaCO₃. Both coir and silk squash is maintained constant weight proportion of 10 wt. % and 5.7 wt. %, respectively, whereas as CaCO₃ is varied with three different proportions (0, 2 and 4 wt. %). Mechanical and dielectric properties were evaluated on the fabricated composite samples. Influence of filler content on adhesive bonding of the fractured composite samples was studied using Scanning Electron Microscopy (SEM). Higher filler content in the composite attained high mechanical properties, similar with the dielectric properties as well. The potential applications of the present fabricated composite samples are found to be increase in automobile and building industry in near future.

摘要

采用手糊法，通过增强椰壳、丝瓜和CaCO₃制备了天然纤维混杂复合材料. 椰壳和丝饼的重量比例分别为10wt %和5.7wt%，而CaCO₃的重量比例分别为(0、2和4 wt %). 对制备的复合材料样品进行了力学和介电性能评价. 采用扫描电镜（SEM）研究了填料含量对断裂复合材料粘接性能的影响. 填料含量越高，复合材料的力学性能越高，其介电性能也越接近. 研究结果表明，该复合材料样品在汽车和建筑行业的应用前景广阔.
