Effect of Unit Cell on Elastic Properties of Fiber Reinforced Polymer Composite Materials

Authors(4) :-CH Sai Krishna, S Suneel Kumar, Siva Bhaskara Rao Devireddy, Anand Babu Kotta

The mechanics of fiber reinforced composites are complex due to their anisotropic and heterogeneous characteristics. The present work is to evaluate the material properties of fiber reinforced composites for different volume fractions up to 60%. A numerical homogenization technique based on the finite element analysis (FEA) with unit cell was used to evaluate the material properties of unidirectional Kevlar fiber reinforced Epoxy composite. A three-dimensional single and multiple unit cell micromechanical models have been developed by using ANSYS software. The material properties obtained using the numerical homogenization techniques were compared with different analytical methods like rule of mixture, Halpin-Tsai, and periodic microstructure methods. The effect of volume fraction of fiber on predicted material properties of composite is also studied.
