Abstract
The invention relates to improved structural health monitoring, particularly to structural health monitoring of fiber reinforced polymer composites, more particularly at bonded joints and methods thereof. There is provided a method of structural health monitoring a composite structure (), wherein said structure () comprises at least one non-reinforcing thermal element (), such as electrically conductive fibers, comprising the steps of applying a stimulus to cause heating of said thermal element (), removing the stimulus, and measuring the electrical resistance of said element () as a function of time, to provide a thermal decay profile () indicating whether damage has occurred in the composite structure ().
