Textile Reinforced Cementitious (TRC) sandwich composites are innovative materials that combine the loadbearing capacity of TRC facings, with a lightweight core. However, these materials may fail under early interlaminar debonding, substantially reducing the load-bearing capacity of the composite. For this reason, thin TRC sandwich composites are subjected to three-point bending test, and monitored with Acoustic Emission (AE), and millimeter wave (MMW) spectrometry.
