Abstract

This work aims to predict the elastic modulus of the fiber-reinforced polymer composites. A representative volume element (RVE) of size 420x420x420 micron has been created in Solidworks with 10%, 17%, 27%, 40% and 54% of fiber volume. The fiber of circular, square and hexagonal cross-section has been considered in this analysis. The symmetric boundary conditions have been applied to the representative volume element. It has been observed from the ANSYS that the results are not exactly similar to the rule of mixture. The results are varying with a change in the cross-section of the fiber. It is noticed that the elastic modulus is increased when the cross-section changes from circular to square to a hexagon with all said fiber volume. It is attributed due to increase in fiber-matrix surface area and the adhesion. Surprisingly it observed that in hexagonal and square fiber cross section cases the elastic modulus has decreased after 40% of volume fraction.
