Abstract Researchers and engineers have shifted their interest from synthetic fibres to natural fibres. These fibres are not only light weight and high-strength materials but are also more economical than the conventional synthetic fibres. Moreover, the natural fibres are eco-friendly and biodegradable. Banana fibre is a bi-product of banana fruit cultivation and hence abundant in nature. Banana fibre being one of the strongest natural fibres can be used for different applications when reinforced with some binding resin. Epoxy resin has excellent binding properties and is thus suitable matrix for composite formation. As it has been widely discussed in previous studies that fibre loading or fibre volume fraction affects mechanical strengths and properties of natural fibrereinforced composite, this study is aimed finding the relation between the fibre volume percentage and the load-bearing capacity of banana fibre-reinforced epoxy composite material by data-driven decision method. In the finite element analysis conducted on the banana-epoxy composite, it has been seen that the composite bear maximum tensile load of up to 7956 N, flexural load of up to 411 N and has hardness of up to 167.28. On the basis of this study, it can be said that due to excellent load-bearing properties, banana-epoxy composite can be used for various medium to high-load industrial applications. The following paper also proposes an analytical relation based on the regression model superposition of the results of tensile, flexural and hardness test simulation conducted by finite element analysis software ANSYS 16.0 which was prepared on Minitab 19 software.

1 Introduction Natural fibre are plant-derived fibres such as banana fibre, wood, sisal, hemp, coconut, cotton, kenaf, flax, jute, abaca, bamboo and wheat straw [1]. These fibres when reinforced with plastic binder form a hard composite material. The development of synthetic fibres was seen as a better alternative to the conventional forms of materials such as steel and aluminium. The synthetic fibres are stronger as compared with steel and even lighter than aluminium. The natural fibre composites being comparatively less strong have strength up to * Upendra Sharan Gupta [email protected] 1
