© 2016 Elsevier LtdSince the discovery of graphene, various industries such as aerospace and automotive are trying to utilize this fascinating nanofiller to enhance components' performance. An important issue in the processing of nanoengineered composites is the interaction and potential filtration of nanofillers by the porous microfibre preform during liquid moulding processing. Here we demonstrate the filtration effect of graphene nanoplatelets (GNPs) during resin infusion of nanoengineered hierarchical composites, and for the first time we have successfully quantified this filtration effect by both electrical and optical methods. In addition, an alternative spraying method to deliver GNPs into composite laminates was also evaluated.
