description	Regarding thermal, mechanical and electrical properties, substantial prospective advances have been offered by Nanotube-reinforced polymers in comparison with pure polymers. This project studies the extent to which the effective stiffness of these materials can be influenced by the characteristic waviness of nanotubes embedded in polymers.

According to the obtained results, nanotube waviness causes a decrease in the effective modulus of the composite compared to the straight nanotube reinforcement. The degree to which this decrease happens depends on the ratio of the sinusoidal wavelength to the nanotube diameter.
