STUDY OF CARBON NANOTUBE REINFORCED POLYMERIC COMPOSITE

Abstract

It was planned to develop a multifunctional composite of CNTs for this we grow the CNTs on carbon fibre cloth by CVD method. These CNT grown carbon fiber cloth were used as re-inforcement in epoxy resin matrix to develop hybrid CF-CNT composite. The growth morphology and the other characteristics of the as grown CNTs were analysed by SEM, TEM, FTIR, TGA, and XRD which confirmed the nature of these tubes as multiwalled and the wall diameter ranging from 10 to 60 nm. The flexural strength (FS), modulus of the composite and hardness shown remarkable improvement. Thermal conductivity both in the CF direction and transverse direction shown good result. The thermal conductivity in transverse direction show about 10 times increment over thermal conductivity shown in CF direction.
