Keywords: MWNT/Reinforcement/Dispersion//Load transfer/SEM
This paper presents the synthesis of epoxy based Multiwalled Carbon nanotubes (MWCNTs)
reinforced composites by method of sonication. The variation in the nature of reinforcement
(Aligned & Randomly oriented MWNTS) has resulted in the improvement of mechanical
properties like flexural modulus, tensile strength and hardness. A small change in chemical
treatment of the nanotubes has a great effect in the mechanical and morphological properties
of nanocomposites due to effective load transfer mechanism and state of dispersion. The
change in properties has been verified by optical microscopy and Scanning electron
microscopy. Apart from that the prepared composites has been treated under different
temperatures (like hot water, room temperature and liquid nitrogen temperature) and the
change in mechanical as well as morphological nature has been verified by SEM of
Fractographic surface this proved the elasticity and ductility of the composites.
