Abstract

Many techniques are in development to detect and quantify damage in Carbon Fiber Reinforced Polymers (CFRP) structures. All the techniques have advantages and disadavantages in accuracy, expense, robustness and level of instrumentation. Almost all involve sensing of strains or acoustic waves using embedded or surface mounted optic fibesr or piezo transducers. An alternative, relatively unexplored, is the electrical potential technique, whcih exploits the electical conducitivyt of carbon fiber as a damage sensing element. The technique consists of measurement of potential distribution in CFRP laminates before and after delamination damage is formed by an impact or other event.
