Abstract:Impacts can degrade the strength of composite structures; thus, impact damages should be monitored and repaired. In this study, a novel composite consisting of carbon nanotube film and glass fiber-reinforced thermoplastic was thermoformed. The fabricated smart composite demonstrated self-sensing and self-healing capabilities for damage caused by low-energy impacts. Elastic deformation of the composite caused by a 0.5-J impact was monitored from the immediate change in resistance of approximately 0.25 Ω. Intern… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
