Influence of glass fiber hybridization on flexural and water absorption behaviour of banana fiber reinforced epoxy composites

Abstract

The majority of vehicle constructions used in the aviation, automotive, and marine industries are subject to various loads. These constructions are more vulnerable to flexural stress, as can be observed. Under the influence of flexural loads, structures can gradually suffer harmful deterioration. The resistance of curved banana/glass fiber reinforced hybrid composites to flexural stress is very important. This research is aimed to examine the influence of glass fiber hybridization on flexural and water uptake percentage of banana fiber reinforced epoxy composites. Glass fiber is a manmade fiber composed mainly of silica, known for its high strength, rigidity, and resistance to heat and chemicals. Banana fiber, in contrast, is a natural fiber derived from the banana plant, offering moderate strength, flexibility, and biodegradability. Glass fiber finds applications in industries requiring strong and durable materials, while banana fiber is sought after for its sustainable and eco-friendly characteristics. In this work, we have fabricated the banana fiber reinforced epoxy composites by adding glass fiber from 0 to 20 weight% through hand layup technique. Then, flexural test and water absorption test has been investigated as per ASTM standards and compared the hybridization effect of glass fiber. From the findings, it is determined that, increase in weight % of glass fiber increasing the flexural behaviour and water resistance of the composites.
