Abstract Scope Single edge notched bend (SENB) tests were carried out to evaluate fracture behavior of neat epoxy and CNT/epoxy nanocomposites. Testing results showed that critical stress intensity factor (KIC) increased with increasing amounts of CNTs and reached peak values at a CNT weight fraction of 0.3wt%. Max 31% enhancement in KIC was found as compared with neat epoxy. Further increases in CNT content resulted in a relative degradation of nanocomposite KIc due to local stress concentration associated with agglomerated CNT. Fractography analysis results showed that, due to bridge effect of CNT, smaller cleavage plane size and higher surface roughness was found in nanocomposite than neat epoxy, and dispersion of CNT in matrix was characterized by cleavage planes size. Quantitative micrograph (QM) analysis results showed that average size of cleavage plans decreased from average 20um of neat epoxy to average 2um of 0.3wt% CNT/epoxy.
