Polycarbonate based multifunctional self-sensing 2D and 3D printed structures f...
Costa, P.; Dios, J. R.; Cardoso, J.; Campo, J. J.; Tubio, C. R.; Gonçalves, B. F.; Castro, N.; Lanceros-Méndez, S.Different polycarbonate materials have been reinforced with carbon nanotubes to tune electrical conductivity and to induce piezoresistive self-sensing capabilities. Further, the composites were processed by solvent casting and fused deposition modelling (filament for 3D printing) methods. An electrical conductivity percolation threshold of ≈0.3 wt.% has been found for solvent casted films, whereas samples proce...
High deformation multifunctional composites: materials, processes, and applicat...
Costa, Pedro,; Nunes-Pereira, J.; Tubio, C. R.; Dios, J. R.; Lanceros-Méndez, S.Structural health monitoring (SHM) is a non-destructive process of collecting and analysing data from structures to evaluate their conditions and predict the remaining lifetime. Multifunctional sensors are increasingly used in smart structures to self-sense and monitor the damages through the measurements of electrical resistivity of composites materials. Polymer-based sensors possess exceptional properties for...
Functional piezoresistive polymer-composites based on polycarbonate and polylac...
Dios, J. R.; Gonzalo, B.; Tubio, C. R.; Cardoso, João; Gonçalves, Sérgio; Miranda, Daniel; Correia, V.; Viana, J. C.; Costa, Pedro; Lanceros-Méndez, S.Multifunctional composites for deformation sensing applications have been developed by solvent casting based on polycarbonate (PC) and polylactic acid (PLA) reinforced with carbon nanotubes (CNT). Composites shows homogeneous filler dispersion and low percolation threshold at 0.1 and 0.06 wt% CNT content for PLA and PC, respectively. The maximum electrical conductivity obtained for the larger filler contents is...
