Abstract

This article provides an overview of the modeling of the effective thermomechanical properties of the multifunctional carbon nanotube (CNT) reinforced hybrid composites for advanced structural applications. The novel constructional feature of such multifunctional CNT-reinforced hybrid composite is that CNTs are radially grown on the circumferential surfaces of the carbon fiber reinforcements. Several micromechanical models have been developed to predict the effective thermomechanical properties of these multifunctional CNT-reinforced hybrid composites. The waviness of CNTs is intrinsic to many manufacturing processes and influences the thermomechanical behavior of CNT-reinforced composites. An endeavor has also been made to investigate the effect of wavy CNTs on the thermomechanical properties of the multifunctional CNT-reinforced hybrid composites. Radially aligned CNTs grown on the circumferential surfaces of the carbon fibers assure that the CNT-reinforced hybrid composites are truly multifunctional and may be a promising advanced next generation composite for structural applications.
