Fabrication methodology and hardness influenced by hybrid layer of a novel Entada Rheedii and banana fibre reinforced epoxy resin composite

Abstract

In this study, the hardness properties of an innovative hybrid composite made of Entada rheedii and banana fibres mixed with epoxy resin were evaluated. A hand lay-up procedure in single or double layers was followed by fibre infusion. In comparison to synthetic and natural fibres, these combinations showed superior reinforcing and provided advantages including waste reduction. Utilising these combinations had the benefit of reducing waste disposal and treatment problems frequently encountered with synthetic composites. The project sought to improve material lifecycle management by utilising biodegradable polymers in industries like automotive, marine, and aerospace. In polymer composites, natural fibres are preferred due to their durability, low weight, cost-effectiveness, and environmental friendliness. Entada Rheedii, a new natural fibre that will improve the performance of epoxy composites, was introduced in the research. Rockwell-B hardness tests performed on the composite with double layers of Entada Rheedii and banana fibre at 45% volume fraction exhibited the highest hardness at 67 HRB. This hybrid composite holds promise for marine applications requiring essential hardness properties.
