Analysis of hybrid composite with moisture defects using finite element method and micromechanics

A unidirectional two different fibers reinforced hybrid composite lamina is analyzed using micro mechanics with the support of finite element method. The circular cross sectional fibers are assumed to be distributed in a hexagonal array. Different combinations of two fibers are studied to notify the hybrid effect on the final properties of composite lamina. The effect of the environment (with phase properties degraded due to the moisture effects) on the properties of hybrid composites is also evaluated. Further, the research is concentrated on the nano based hybrid composites. The objective of the work is attained by applying homogenization techniques. A new combination of material is proposed in place of regular hybrid composites from the findings of finite element results. The longitudinal directional properties have been found to be insignificant with the environment and nano reinforcement; however, there was significant variability in the transverse strength properties.
