Thermomechanical Analyses of Alkali-Treated Coconut Husk-Bagasse Fiber-Calcium Carbonate Hybrid Composites

Natural fiber-reinforced composites can contribute to reducing carbon footprint goals due their ability reduce overall product weight, bio-diverse feedstocks, and recyclability potential. In this work, natural fiber-based containing the reinforcement of coconut husk bagasse fiber with calcium carbonate (CaCO3) ingredients were prepared analyzed. The analyzed for mechanical, thermomechanical, morphological properties. reinforcements chemically functionalized using 5% w/v NaOH enhance interactions epoxy resins. chemical functionalization created perforation on surface, improving interlocking fibres resin material strengthening mechanical performance composite. developed modified treatment resulted in increased tensile strength (64.8%) flexural (70%). influenced hydrophilicity, water absorption treated was reduced more than five times compared unmodified composites. Scanning electron microscopy revealed changes modification, underlaying mechanism contraction, enhanced matrix interface adhesion strengthening. Thermal analysis confirmed that alkali improves crystallinity thereto degradation temperature (both husk), which is 375.27 °C, highest amongst hybrid
