Glass/
Caryota urens
hybridized fibre-reinforced nanoclay/SiC toughened epoxy hybrid composites were prepared and characterized for its mechanical, drop load impact toughness, hydrophobicity, and fatigue behaviour. The rapidly increasing demand in polymer matrix composites proportionally increasing the environmental pollution and now this factor is a prime concern for all researchers worldwide. Thus, this research study is aimed to prepare and investigate the natural fibre-based polymer matrix composites by keeping the environmental factors in consideration. Replacing the synthetic fibres completely by natural fibre also not a great development since, the natural fibres are inferior in useful properties. Thus, in this present investigation, a hybrid form of glass-
Caryota urens
fibre was introduce as primary reinforcement for nanoclay-SiC toughened epoxy resin matrix. The mechanical and drop load impact results revealed that the addition of nanoclay and SiC into the epoxy resin improved the toughness together with glass-
Caryota urens
hybrid fibre. Moreover the addition of nanoclay and
Caryota urens
fibre in epoxy resin matrix improved the fatigue life cycle up to 55,182 for 50% of ultimate tensile stress. The hydrophobicity of silane-treated reinforcements gives marginal loss in water absorption compared to bare epoxy resin. These properties improved hybrid fibre epoxy composites could be used in many engineering applications.
