Laser welding of carbon nanotube networks on carbon fibers from ultrasonic-directed assembly

A facile method to prepare carbon nanotube/carbon fiber hybrid fiber was explored by an intermittent ultrasonic-directed electrophoretic deposition, and a following laser transient heating was used for welding the deposited carbon nanotubes on carbon fibers at joints. The formed porous networks were favourable for resin infiltration, leading a significant increase in interfacial bonding strength of carbon fiber reinforced polycarbonate composites.
