Abstract: Fibre reinforced composite materials have become a popular engineering material type. They have excellent mechanical characteristics, a wide range of flexibility in design, and are simple to fabricate. Fibre reinforced composites (FRP) are gradually displacing traditional materials in a wide range of applications, including aircraft, automobiles, containers, space vehicles, offshore constructions and pipelines, sporting goods, and electrical appliances. The mechanics of FRPs, on the other hand, are complicated due to their anisotropic and heterogeneous properties. To determine the elastic behaviour of the composite, a representative volume model was considered in this paper, and a finite element model incorporating the required boundary conditions was developed using FEA ABAQUS software. The results of the analysis are compared to those acquired from numerical calculations, and it is seen that they are in good agreement and are applicable to all volume fractions of the composite.

Keywords: cotton waste; effective elastic constants; ABAQUS; rule of mixture.
