The over-utilisation of petrochemical products and human-affecting hazardous synthetic material has created pollution in the atmosphere. To bring solutions to such effects, research scientists and industrial professionals are keenly interested in producing a less dense and harmless product material by using natural compounds over synthetic ones. This study investigates the mechanical and fatigue properties of vinyl silane–treated areca fibre and bronze nanoparticles under aged conditions. The primary aim of this research work is to investigate how the silane-treated reinforcements in the composites enhance the properties of composites under the ageing process. The bronze nanoparticle and natural areca fibre were separately treated with vinyl silane to enhance the adhesion. Polyester resin with methyl ethyl ketone peroxide hardener was employed as the matrix. Composite plates were prepared via the hand layup process and subjected to ageing at 50 °C and 70 °C for 30 days. According to results, the specimen N2 containing 3 vol.% of bronze nanoparticles exhibited superior properties across tests, with notable values such as tensile strength of 132 MPa, flexural strength of 174 MPa, ILSS of 25.3 MPa, rail shear strength of 20.31 MPa, in-plane shear strength of 61 MPa, Izod impact value of 4.98 J, and fatigue result at 75% of UTS of 30,214. SEM analysis revealed well-dispersed nanoparticles and treated fibres. These findings suggest that vinyl silane–treatment enhances the durability and performance of composites under ageing conditions. Thus, these superior mechanical and cyclic load-bearing capacities in the composite could be utilised in areas such as interior parts of automobiles, aviation, defence weapon manufacturing, and domestic appliances. |
