N2 - Production of novel damage sensor system for carbon fiber-reinforced composite structures is presented. It utilizes carbon fibers as self-sensing sensors. Two key components are the fabrications of electrodes required to measure electrical resistivity changes due to damage, and the development of robust data interpretation scheme to diagnose the damage stage. The former takes the advantage of new technology based on the thermal spray process in which molten copper are directly deposited onto composite laminate surfaces to fabricate network of electrodes. The latter task relies on the simulation study and the optimization/inverse analysis to estimate damage state through processing of measured data. The initial experimental measurements on composite laminates with artificially made damage indicate increased resistivity among thermal sprayed electrodes.
