Numerical Analysis of Hybrid Carbon Fiber Composite Specimen and Validation of Results

This paper focused on numerical study of hybrid composite specimens, which was experimentally done by preparing according to ASTM standards. Hybrid Composites are the formed by the combination of more than one reinforcement and matrix, which exibits very good properties compared to that of single reinforcement composites. These materials shows better flexibility when comparing with other composites. Hybrids consists of two types of fibers a high modulus fiber and a low modulus fiber. The high-modulus fiber provides better stiffness and high load bearing capacity, whereas the low-modulus fiber provide more damage tolerance and reduces the material cost. The mechanical properties of a hybrid composite can be altered by varying volume ratio and stacking sequence of different plies. The numerical study was conducted by developing specimen models in Solid Edge ST4 and later importing to ANSYS Workbench 15.0. The boundary conditions were applied and analysis results compared with that of experimental results to suggest its further applications.
