Improved interfacial properties of carbon fiber composites by building stress transition layer with carbon nanotubes

For the purpose of improvement in interfacial property of carbon fiber composites through a facile process, the carboxyl‐functionalized multiwalled carbon nanotubes ( MWCNT s‐ COOH ) were incorporated into the surface of JH ‐T800 carbon fiber using sizing and deposition technology. The surface morphology of MWCNT s‐ COOH ‐modified carbon fibers and fracture surfaces of unidirectional carbon fiber composites were observed via scanning electron...
