| Abstract [eng] |
Interlaminar delamination and buckling of the core are crucial defects in sandwichstructured composites. Not identifying these damages in time can lead to further interlaminar cracking, fibre fracturing and a total composite failure. This work aims to develop a self-sensing sandwich-structured composite modified with carbon nanotubes (CNT) and through-thethickness conductive dip-coated aramid honeycomb using MXene nanoparticles. The morphology of partly-delaminated Ti3C2Tz MXenes and CNT modified glass fibre composite is investigated using scanning electron microscopy. The structural health monitoring method proposed in this research is based on a simple piezoresistive effect in different composite layers. The damage location in the composite is evaluated according to electrical resistance change and intensity. |
