Abstract

Due to strict regulations, the reuse of industrial by-product as filler material in developing any novel composites along with using natural fibres as reinforcements has become increasingly mandatory in recent times. Hybrid composite laminates are developed by combining organic natural fibres and in-organic filler material in polymer matrix. Hybrid laminates are formulated by reinforcing 10 wt.% of linen fabrics and 10 wt.% of jute fabrics in fumed silica (1 wt.%, 2 wt.% and 3 wt.%) incorporated epoxy matrix. The hand lay-up method is utilised for polymer hybrid laminates’ formulation. Mechanical properties (such as tensile, flexural and impact) and thermal stability of the formulated hybrid laminates are assessed. Morphological analysis of the hybrid laminates is analysed. The hybrid laminate formulated using 2 wt.% fumed silica incorporated has registered superior mechanical properties. Due to agglomeration, the mechanical properties diminished beyond 2 wt.% fumed silica addition. Whereas 3 wt.% fumed silica incorporated hybrid laminate has registered maximum onset temperature of degradation.

摘要

由于严格的规定，近年来，在开发任何新型复合材料以及使用天然纤维作为增强材料时，工业副产品作为填充材料的再利用已变得越来越强制。混合复合层压板是通过将有机天然纤维和无机填充材料结合在聚合物基质中而开发的。通过在掺入的环氧基质中的气相二氧化硅（1％，2％和3％）中增强10％（重量）的亚麻织物和10％（重量）的黄麻织物来配制混合层压材料。手工铺层法用于聚合物混合层压板的配方。评估配制的混合层压材料的机械性能（例如拉伸，挠曲和冲击）和热稳定性。分析了混合层压板的形态分析。混合层压板使用2 wt。掺入的气相二氧化硅具有优异的机械性能。由于附聚，机械性能降低超过2重量％的气相二氧化硅添加量。而掺入有3％（重量）的热解法二氧化硅的混合层压材料具有最高的起始降解温度。
