Self-Sensing Fiber Reinforced Composite (CRADA Final Report)

Abstract

The project aimed to demonstrate a scalable coating process to adhere nanoparticles to the surface of fibers and fabricate composites with in-situ damage detection abilities and simultaneous mechanical performance enhancements. Carbon fiber (CF) composites have the inherent problem of hiding damage within the structure with no visual indications on the surface. Therefore, a technique to monitor for damage or excessive stress on the composite is necessary to ensure its safety and avoid catastrophic failure. This capability will be desired in future transportation vehicle designs, such as in cargo and surveillance drones developed by Dronesat, LLC, (Dronesat) who was the industrial partner on this project.
