Abstract

In this work electrical resistance measurements were utilized as a mean to assess the dispersion of Graphene Oxide nanoinclusions into CFRP laminates. This approach involves resistance measurements in the through-thickness and transverse directions of the laminates. Measurements were conducted in CFRP laminates containing Graphene Oxide dispersed into the epoxy matrix with filler contents of 1wt% and 5wt%. The morphology of the samples was examined by means of optical microscopy and scanning electron microscopy. The obtained results suggest that at low filler contents, 1wt%, the dispersion is uniform into the bulk of the sample, while at higher filler loadings, 5wt%, there are indications of non-uniformity due to the formation of areas with higher filler concentration.
