| Components made of glass fiber reinforced polymers often fail under interlaminar shear loading conditions, which can significantly compromise their structural performance. To solve this problem, the piezoresistive effect of graphene nanoplatelets integrated into the glass fiber reinforced polymers is proposed as a technique to monitor and detect interlaminar shear failure. For that, short beam shear specimens were prepared from glass fiber reinforced polymers modified with graphene nanoplatelets, and changes in electrical resistance caused by quasi-static bending forces were recorded to monitor the electromechanical behavior and failure mode. The interlaminar shear strength was obtained at around 30 MPa for both composites (0.75 and 1 wt.% graphene nanoplatelets). Results indicate that the incorporation of graphene nanoplatelets has a minimal effect on the electromechanical behavior curves, and both concentrations (0.75 and 1 wt.%) provide good electrical sensing capability for interlaminar shear failure in glass fiber reinforced polymers, which can be used as an active tool for health monitoring applications across a wide variety of industrial applications, especially where this failure mode may occur. | ||
