摘要: In this paper, interfacial healing was achieved in carbon fiber composites via local heating generated by photothermal effect of gold nanoparticles (Au NPs). The damage can be locally repaired melting polymethyl methacrylate and re-infiltrating to form a new interface. Au NPs were coated on fibers electrophoretic depositions as nano-heaters the coating density controlled varying electrophoresis time. ability confirmed micro bond test comparing shear strength surface morphology samples before after healing. Experimental results showed that irradiation intensity played key role. Repeated healings with only small reduction strength.
