PREDICTION OF ENGINEERING CONSTNATS OF CARBON T300/ EPOXY COMPOSITE USING SOFT COMPUTING

摘要

The present work deals with the micromechanical analysis of carbon (T300) fiber reinforced in epoxy resin whose fiber volume fraction vary from 20%???70%. A three- dimensional model with necessary boundary conditions has been developed from the unit cell of square pattern of the composite to predict the engineering constants like longitudinal young’s modulus (E1) , Transverse modulus (E2), major poisson’s ration ???12 and In-plane shear modulus (G12). The problem was modelled using ANSYS software and the results obtained from FE model was validated with the bench mark results. In this work an attempt has also been made to develop the fuzzy logic rule based model to predict the engineering constants of carbon (T300) fiber reinforced epoxy composite. From the results it was concluded that fuzzy logic model can be effectively used to predict the engineering constants of fiber reinforced composites.
