Multi-Wall Carbon Nano Tube (MWCNT) reinforced composite structure has been widely researched. However, there are a few studies report the MWCNT as a sensor and an actuator integrated in the same composite structure to form a multifunctional composite. The composite used in this study was based on commercially available thermosetting epoxy polymer, dispersed with thermoplastic particles, and MWCNT. Multifunctional MWCNT reinforced epoxy polymer composite was fabricated and tested. The specimens were damaged by the three point bending load. The sensor and actuator system automatically detected the damage and triggered the out electric power to heal the damages. The healing efficiency was evaluated by measuring resistant of composite.
