The influence of the average surface area of different graphene nanoplatelets (GNP) on the thermo-electrical behaviour, associated with Joule heating, and the attenuation of electromagnetic signals of epoxy composites has been studied, analysing the effect of the morphology obtained as a function of the dispersion time by ultrasonication and...

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...
