摘要

The present research aims to develop eco-friendly green composites using cashew nutshell liquid (CNSL) as a bio-based resin and natural fibres such as manga bamboo, areca nut palm leaf sheath, and coconut leaf midrib as reinforcements. To enhance mechanical integrity, fracture resistance, and load transfer efficiency, graphene, single-walled carbon nanotubes (CNTs), and silicon dioxide nanoparticles were incorporated in selected weight ratios. Prior to composite fabrication, fibres were treated with silane and alkali solutions to improve interfacial bonding. A total of eighty-one composite samples were produced using compression moulding, vacuum bagging, and hand lay-up techniques, with twenty-seven specimens prepared by each method. A Taguchi L81 orthogonal array was used to evaluate the combined influence of five factors i.e., manufacturing process, nano-filler type, fibre treatment, fibre type, and fibre weight%, each at three levels. The mechanical and water absorption characteristics of the developed composites were analyzed, and scanning electron microscopy was used to study fibre-matrix adhesion, filler dispersion, and fracture behaviour. The optimization study revealed that compression moulding, 10% (by wt) bamboo fibre, graphene nano-filler, and silane surface treatment provided the most desirable combination, achieving a tensile strength of 39.6 MPa, flexural strength of 32.5 MPa, and water absorption of 12.9%. The enriched mechanical properties and reduced moisture uptake confirm the potential of CNSL-based green composites as a sustainable and lightweight material suitable for future structural and engineering applications.
