Abstract

The usefulness and promise of composite materials in various industrial contexts have received extensive attention in recent years. Chemical treatment and weight fraction modifications are the subject of this investigation into the shore hardness qualities in woven E-Glass, Woven Jute, and Kenaf Hybrid composite laminates. The key objectives are to analyse how the NaOH chemical treatment affects the laminate's hardness and how the fibre weight fraction affects stiffness. Our process entails making composite laminates in a range of circumstances, from raw to treated (NaOH), and from 20% to 25% by weight. Testing the Shore hardness of the laminates is a crucial tool for determining their stiffness. According to the findings, NaOH chemical treatment clearly improves the shore hardness, which is useful for its enhanced rigidity. The importance of optimising the weight fraction of the composite design is further emphasised by the fact that raising the weight fraction of fibres typically leads to improved hardness. This study elucidates the value of shore hardness testing for characterising composites and evaluating the effects of treatment and weight fraction modification. Considering the importance of stiffness and durability in numerous fields, research has far-reaching consequences. The research also adds to the field of material engineering by advocating for environmentally friendly options by using natural fibres such jute and kenaf. In sum, the findings of this study deepen our knowledge of composite materials and pave the way for novel, eco-friendly materials and processes.
