Fiber-reinforced thermoplastics (FRTP) have better specific strength and specific modulus than metal and ceramics. In recent years, improvement of mechanical properties of FRTP due to addition have been considered for weight reduction of FRTP. In this study, CNT dispersion effects on weld strength of injection molded fiber reinforced thermoplastic were investigated. It was found that the addition of CNTs can increase the weld strength. It was found that the addition of CNTs can increase the weld strength. It is suggested that this effect is manifested the increase of elastic modulus of base materials and interaction force generated at the interface with resin and fiber by the addition of CNT. In addition, the interaction force between resin and fiber was found to be dependent on the injection temperature.
