| Abstract: | Conductive polymer matrix composites were prepared by using acrylonitrile-butadiene-styrene (ABS),conductive polyaniline (PANI) and conductive carbon black (CB). The relationship of the temperature during the welding with the welding time under different welding voltage was examined. The resistance welding of polycarbonate (PC) was investigated by using the conductive polymer matrix composites as a heating resistor. Results indicate that the welding voltage and welding time have a strong effect on the interface bonding in resistance welding. Within a suitable power,the optimal welding temperature can be obtained in fixed time. A desired joint is formed at the welding interface due to the mutual melting phenomenon between polymer resistor and base materials,and the joint strength reaches up to 25.4 MPa. A novel method for plastic resistance welding using conductive composite materials as the heating device was explored in this research work. |
