Thermomechanical Response and Interphase of a Novel Carbon Nanotube Array-Reinforced Laminated Composite Material

摘要

Polymeric laminated composite materials have been widely used in aerospace and other high performance applications due to their high in-plane mechanical properties and light weight. However, the low interlaminar mechanical properties constrain its more widespread use due to the absence of reinforcement in the through-the-thickness direction. A solution to this problem is being addressed through the creation of a nanoreinforced composite material with an interphase between the composite plies that increase shear stress transfer. An aligned dense multi-walled carbon nanotube (MWCNT) array is considered as the reinforcement to increase the interlaminar mechanical properties of the laminated composite material. The fabrication process the mechanical response under interlaminar shear and in-plane loading are presented in this paper. It is shown that the nanoreinforced composite material possesses superior interlaminar mechanical properties than regular non-reinforced composite materials.
