Název v původním jazyce

Epoxy/glass fibres laminates with integrated layer of carbon tubes decorated by Ag clusters for deformation detection

Popis výsledku v původním jazyce

With the aim to develop a multifunctional material, two concepts were joined, composite manufacturing and sensing. Using vacuum infusion technology, carbon nanotubes (CNTs) filtered in a polyurethane membrane were integrated in a glass fiber reinforced epoxy laminates. In this study a modified CNTs decorated by Ag inclusions were used as strain sensors for deformation detection, based on the principle of crack sensors, were ultrahigh sensitivity is attributed to disconnection-reconnection process between the nanotubes and increased by the metal-metal (Ag-Ag) link. CNTs with Ag inclusions sensors showed extraordinary results in measuring changes in the electrical conductivity compared with pure CNTs, after applying pre-strain forces which increases strongly the sensitivity to changes in electrical resistance. CNT-based sensing elements are capable to deliver process monitoring performance combined with additional functionality such as passive antenna functionality or gas detection, to be utilized over life time. Furthermore CNT-based patches can be used as heating elements.
