Abstract:

As delamination cracks are usually invisible, it is difficult to identify delamination cracks within carbon-fiber reinforced polymer CFRPcomposite laminates. The difficulties in finding laminate damage by visual inspection raises the need of monitoring methods that use electric resistance changes within the laminates. The method adopts conductive carbon fibers as sensors as well as mechanical reinforcements, that is, in a sense self-sensing. In the present study, the new analysis method is extended to a new electric current arrangement that is used for the addressable conducting network ACN. The addressable conducting network adopts grid type electrodes mounted on the both sides of the target CFRP laminate in orthogonal direction.
