Research Abstract

Experimental methodologies for evaluating load transfer at the interface between CNT and matrix of CNT/polymer composites were examined. In-situ SEM and TEM observation methods for evaluating the composite specimens subjected to tensile loading, and nano-pull-out testing systems for evaluating interfacial shear strength were established. These test methods were used to reveal the macroscopic and microscopic mechanical behaviors of CNT/PEEK composites.
