Epoxy is widely used as matrix in advanced high performance polymer composites due to its mechanical properties, compatibility with most reinforcement, chemical resistance, low cost etc. But, its major drawbacks are low fracture toughness and damping properties, which can be improved by adding reinforcement phase. Carbon nanotube and graphene are most favourable choice as reinforcement, due to their chemical compatibility, as well as, exceptionally impressive mechanical and thermal properties. Present study reports a comparative analysis between carbon nanotube and graphene as reinforcement to epoxy. The behavior of these two nanofillers and their interaction with polymer matrix can be quite different, considering their vastly different morphology, leading to different mechanical and thermal properties. Tensile test, fracture analysis and DMA studies are carried out to quantify the difference in improvement in properties with different amounts and type of reinforcement. Further analysis is carried out to understand the differential mechanisms acting behind.
