Interfacial and fatigue-resistant synergetic enhancement of carbon fiber/epoxy hierarchical composites via an electrophoresis deposited carbon nanotube-toughened transition layer

To synergistically improve interfacial and fatigue-resistant performance of carbon fiber/epoxy composites, a transition layer reinforced by oxidized multiwall carbon nanotubes (OCNTs) was built. OCNTs were integrated onto carbon fibers using a continuous electrophoretic deposition method. Results of static and fatigue tests showed that compared with composites without OCNTs, the hierarchical composites not only showed increases of 33.3% in...
