Assessing the damage evolution of composites containing embedded fibre optics

In the work presented in this article, the nondestructive technique known as micro-computed tomography (micro-CT) was used to investigate the internal state of composite laminates containing embedded fibre optics. The laminates were subjec ted to cyclic loading and the damage was followed up in order to determine if the sensors affected composite lifetime. The experiments showed no significant evidence of damage related to the sen sor’s presence.
