“…To characterize the waviness morphology and understand the waviness effect of the CNTs and micro-fibres on the elastic properties of composites, extensive investigations have been carried out, experimentally [12], analytically with the aid of micromechanics [8,11], numerically with the finite element (FE) analysis [13], or with a combination of the FE-micromechanics methods [4,5]. Although the overall properties of a nanocomposite can be measured by experiment, it has been extremely hard to explore the mechanisms of property variations of nano-composites in this way, primarily due to the great number of influential factors.…”
