Nano-Mechanical Properties of Coiled Carbon Nanotube Reinforced Epoxy Composites
The applications of carbon nanotubes benefit to a wide range of engineering, applied physics and biomaterials areas for their superior mechanical and electrical properties. Recently, coiled carbon nanotube (CCNT) has opened a new alternative to reinforce traditional advanced composites. Their coiled shapes are considered to induce mechanical interlocking between the nanotubes and matrix which result in the enhancement of fracture toughness and mechanical strength of the composites. In this study, nanomechanical properties of CCNT reinforced epoxy composites with varying weight percentages (0, 1, 3, and 5 wt %) of nanotubes were measured by the nanoindentation technique. Hardness and elastic modulus measurement of the composites were conducted.
