A mean-field micromechanical approach to design of multiphase composite laminates

A mean-field micromechanical model has been applied to design and analysis of nonlinear behavior of multiphase composite laminates. The analysis accounts for visco-elastic–plastic deformations of the composites. Using the developed model, a numerical study has been made, which includes the tensile behavior of angle-ply carbon fiber/polycarbonate composite laminates, thermal expansion behavior of angle-ply grass fiber/polypropylene composite laminates, and thermo-mechanical behavior of angle-ply grass fiber/SiCw/polycarbonate hybrid composite laminates with a high thermal dimensional stability. The simulation has well represented experimental data and provided a new insight into design of multiphase composite laminates.
