Detecting the presence of water in sandwich structures


An integrated device is able to detect water in honeycomb structure

The sandwich structure with honeycomb core is vulnerable to a problem that may limit its service life, also reducing the reliability thereof: the possibility of liquid water entering the core. The problem of the entry of liquid water may occur when the skin has breakages (even at a microscopic level) that compromise the integrity, or even, for very thin skins, porosity.
