Abstract
The application of composite components in the load-carrying structure boosts the booming of health monitoring techniques so that the crucial damages information inside the composite can be perceived to ensure the secure state of the whole composite. This paper presents a promising self-sensing nanocomposite equipped with carbon nanotube buckypaper sensor to realize the health monitoring function. The CNT-based composite laminates with different contents were compared under monotonic and cyclic flexural loading. The sensor with lesser content of CNT proved to be more qualified for strain monitoring and damage prediction with high sensitivity, stability, and durability.
