Damage sensing was one of the most important methods for the evaluation of micro-cracks inside structural composites such as, airplane, vehicle, vessel and building. Damage sensing paste was made as paint type and optimum paste condition was evaluated using nanocomposites. Damage sensing property was investigated using uni-directional tensile test. Electrical sensing data was compared with elongation and tensile strength. Durability of paste was evaluated using dynamic fatigue test. Damage sensing property of conventional adhesive type matrix was better than constructional adhesive type, whereas mechanical durability of construction adhesive type was better.
