This thesis deals with damage detection via electrical resistance measurements on carbon fiber reinforced polymers and on carbon nanoparticle modified adhesive joints. Silver nanoparticle based ink is printed onto carbon fiber reinforced polymers and onto prepregs and mechanical tests with simultaneous electrical resistance measurements demonstrate the possibility to detect delaminations and inter-fiber failures. In addition, impact damage detection is demonstrated for plate specimens as well as for an omega stringer. On carbon nanotube modified epoxy based adhesive joints, electrical resistance measurements show the possibility of accurate detection and localization of impact damages and damages developing in cyclic tests.
