Abstract

A novel, purpose-designed, thin interlayer glass/carbon-epoxy hybrid composite sensor concept is presented here that can be used for structural health monitoring (SHM), offering potential for safer operation in service. The hybrid composite sensors indicate the overload of a structure by exhibiting a change in their appearance when loaded in tension over a predefined strain value. The sensors can be attached to a component either as a structural sensing layer or integrated locally as demonstrated in this study through real-life applications. Furthermore, various test methods have been utilised to characterise the bonded-on sensors including mechanical testing, Digital Image Correlation (DIC) and Acoustic Emission (AE) measurements. An optimal configuration has been identified with the utilised materials that can potentially be used in applications such as sporting goods, civil engineering structures (e.g. truss and bridge elements) as well as pressure vessels.
