Pseudo-Ductile Hybrid Composites with Overload Sensing Capability

MICHAEL WISNOM, GERGELY CZEL, MEISAM JALAVAND and KEVIN POTTER

Abstract


Fragmenting hybrid laminates create a pseudo-ductile response and a striped pattern of fractures and delaminations which can be used as a simple visual strain overload sensor. The mechanism is explained and it is shown how it may be used to detect if a specified strain threshold or a range of different strains have been exceeded. The novel hybrid composite sensor may be used as an indicator patch cocured with composite components or retrofitted/bonded onto the surface of composite or metal components, or be incorporated as an integral load-carrying surface layer with sensing functionality.
