Abstract—This paper is proposed to analyse the multi shaped reinforced elements like carbon fibre, glass fibre and highly dispersed nano sized alumina particles in the matrix of thermoset polymer’s interphase properties. The thermoset epoxy resin was taken as the matrix materials. Fundamental tests like tensile, compressive and flexural were carried out for the different loading condition. The similar test was simulated through the FEA technique using ANSYS and the argument was established to explain the deviation among the results. A third phase material was introduced to represent the inter phase region and the mechanical properties as a function of inter phase strength was reported. In our analysis the different shape and size fiber inclusions were used, i.e., spherical, cylindrical, rectangular, cylindrical fibers with hemispherical ends. The volume fractions of fiber inclusions were varied from 0% to 40% and the FEA analysis was carried out to understand the behavior of material at the different loading conditions. The analysis also extended to calculate the behavior of the hybrid composite which contains glass fiber, carbon fiber and alumina particles in the matrix of epoxy. Detailed analyses of the enhancements of the mechanical properties due to the incorporation of the interphase material were studied.
