CNTs are among the most exciting new material which has been discovered in the last three decades. Since their discovery of CNT , CNTs have generated huge activity in most areas of science and engineering due to their superlative mechanical, thermal, and electronic properties [2,3]. Polymer matrix composites are being utilized in an increasing number of industrial applications including transportation, automotive, aerospace, defense, sporting goods, energy, and infrastructure sectors . This is due to their high durability, high strength, light weight, and process flexibility. The two phase epoxy–carbon composites have been extensively used in last few decades . Traditional fiber-reinforced composite materials made of oriented fiber stacks embedded in a polymer have excellent in-plane properties but have poor through-thickness properties. The CNT reinforcement can improve the through-thickness mechanical properties and resultant nanocomposite can provide high elastic modulus, tensile strength, and fracture toughness .
