Abstract

The tensile modulus of carbon nanotube reinforced polymer composites was calculated with 3-D Finite Element Method. The effects of nanotube orientation and nanotube agglomeration on tensile modulus of the composites were investigated. The simulation results show that the tensile modulus of a nanotube reinforced composite drops sharply either when the nanotubes diverge from the applied load direction, or when the nanotube agglomerations are formed. This finding could explain why the predicted tensile modulus of a nanotube composite, based on the assumption that the nanotubes are fully isolated and aligned in polymer matrix, is much higher than the values obtained from experiments.
