Assessment of Impact Damage in Composites via Self-Sensing Fibers

Abstract

The project goal is the development of novel damage assessment devices for carbon fiber-reinforced composite structures utilizing carbon-fibers as self-sensing sensors. Two key components of this project are the fabrications of electrodes required for electrical inputs/outputs through the composites, and the development of data-processing scheme to diagnose the damage state. The former takes the advantage of new technology based on the thermal spray to directly deposit onto composite laminate surfaces to fabricate network of electrodes. Several conditions were tested and optimal process was identified. The latter task utilized simulations to develop the post-processing approach and preliminary results were promising.
