Textile reinforced cementitious (TRC) composites is a new materials class, offering a sustainable and lightweight alternative to conventional concrete. However, TRCs are still in their relative
infancy and a complete understanding of their response to damage is not yet available. Although theoretical formulations imply that their macroscopic fracture process starts with matrix cracking, in practice interfacial debonding, delaminations and pull-out occur earlier than expected and degrade the mechanical response, therefore the composite full capacity is not reached. Therefore, in order to increase the confidence in the material and its use as structural element, its mechanical performance should be thoroughly understood and monitored. This understanding concerns basically the degradation during operation to ensure no unexpected, brittle failure. A series of experimental campaigns are designed to trigger, isolate and track the detrimental damage mechanisms. Advanced monitoring methods will be combined for the first time in literature in order to develop a multiscale and multispectral integrated monitoring setup. The project extends the current research using Acoustic Emission and combines this method with Digital Image Correlation (to track debonding
zones), X-ray computed tomography (to track micromechanical fracture and quantify the energy dissipation of different damage mechanisms), Acoustic Emission tomography (to map internal damage onset/extension), microscopy and others.
