Size effect of graphene nanoplatelets on the morphology and mechanical behavior of glass fiber/epoxy composites

We investigated the effect of graphene nanoplatelets (GnPs) with two different lateral dimensions on the morphology, flexural, and thermo-mechanical properties of multiscale GnPs/glass fiber/epoxy composites. First, 3 and 5 wt% of GnP-C750 (<1 µm in diameter) and GnP-5 (5 µm in diameter) were individually integrated into epoxy suspension through a combination of calendaring and sonication processes. The GnPs/glass fiber/epoxy composites were...
