Study on Tensile Fracture-surface Morphology of Carbon Nanotube/Epoxy Composites by SEM and FESEM

In this paper the tensile fracture-surfaces of carbon nanotube/epoxy composites as the researched objects were observed using the scanning electron microscopy(SEM) and the field emission scanning electron microscopy(FESEM),the dispersed states of carbon nanotubes in epoxy resin were analyzed,the influence of carbon nanotube content,types and solvents on the micro-morphology of fracture-surfaces of composites were investigated as well.
