Finite Element Analysis on Hybrid Boron-Carbon Composites

Adaptability to different situations and the ease of combination makes composites one of the most extensively used materials in the engineering industries. One of the ways of managing properties of composites is hybridization of different fibers in one composite. This work merely focuses upon the analysis of effective stiffness of Hybrid materials which is carried out using Finite Element Method. A series of models were experimented in a sequence by imposing various conditions on each of them. Boron and Carbon fibers were used primarily for these experiments because of their better compatibility than other combinations of fibers. Due to the difference in diameters of the fibers it was possible to achieve very high volume concentration of fibers. Longitudinal properties of hybrid composites are studied well in literature but prediction of transversal properties was a challenge. The results of FEM modelling were compared with the theoretical predictions and conclusions were drawn.
