Development and characterization of Neem and Arjuna filler composite for sustainable applications
This study investigates the development and characterization of Neem and Arjuna bark filler composite, emphasizing sustainable material innovation. The bio composites were synthesized using a hand lay-up method with varying bark powder compositions and an epoxy resin-hardener matrix. Comprehensive characterization techniques, including FTIR, XRD, SEM-EDX, thermal analysis (TGA, DSC), and biodegradability testing, were employed to assess structural, mechanical, and thermal properties. Results revealed that Arjuna filler composite (AFC) samples exhibited the highest impact strength that is 9.7 kJ/m2 compared to Neem filler composite (NFC) which is 5.18 kJ/m2, attributed to stronger interfacial bonding. FTIR analysis identified functional groups such as hydroxyl and carbonyl, confirming cellulose integration. XRD patterns demonstrated the crystalline nature of cellulose, with neem and arjuna filler composite (NAFC) showing intermediate structural modifications. SEM-EDX analysis highlighted surface morphology differences and elemental compositions, with NAFC presenting a balanced carbon-oxygen ratio indicative of homogeneity. Thermal analysis revealed enhanced stability in AFC that is degradation onset at ∼363.3°C) compared to NFC which is ∼374.8°C, with DSC indicating significant energy absorption during transitions. Biodegradability tests indicated moderate weight changes over 32 days, with NFC and AFC demonstrating synergistic effects in microbial activity and water absorption. These results underscore the potential of neem filler (NF) and arjuna filler (AF)-based bio composite as eco-friendly applications in sustainable packaging, eco-friendly flooring and panel, light-weight composite parts and material innovation.
