■ Rraman spectroscopy and electro-mechanical technique were coupled to study the deformation and failure behaviors of glass fibers with nanocomposite coating. Glass fibers with CNT coating exhibited improved electrical and mechanical properties. The coating with a higher CNT content showed a more efficient stress transfer and higher interfacial shear stress for a given applied strain than the coating with a lower CNT content. The relationship between the fiber stress and the change in electrical resistance against the fiber strain were established.

■ The correlation between the functional groups, interfacial microstructure and behavior of load transfer in carbon nanotube (CNT)/epoxy nanocomposites was reported. The results show that nanocomposites filled with functionalized CNTs exhibit a noticeable G′-band shift in tension while those containing pristine CNTs have a marginal shift. The mechanisms behind this observation are discussed with reference to fractography and thermo-mechanical properties of nanocomposites.
