The electromechanical performance and reversibility of sensitive GNP/epoxy strain sensors were experimentally and theoretically analyzed. Under tensile loads, the strain sensors showed lower sensitivity and more linearity than bulk sensors, behavior attributed to a slight preferential orientation of the GNPs along the in-plane direction. The...

Sensing capabilities of carbon nanotube (CNT)doped adhesive films under bending conditions were investigated. Standard Mode-II coupons and skin-stringer sub-elements were manufactured while their electrical resistance was monitored. Mode-II energy fracture was improved when adding CNTs in comparison to neat adhesive joints due to their...

Conductive epoxy nanocomposites were prepared using two different thickness graphene nanoplatelets (GNPs) as reinforcement, H25 and M25. In both cases, 3 and 5 wt % GNPs was dispersed into the matrix by means of sonication and calandering processes. The piezoresistive mechanisms of these GNPs/epoxy sensors were studied under tensile and...
