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...

In recent years, the interest in monitoring the damage of composite materials by measuring the variation of electrical resistance is increasing because deformations and cracks generated in the structure produce changes in the electrical conductivity of the material. In this work, the structural integrity of glass fiber composite materials with...
