Functionally graded graphene reinforced composite structures: a review
TL;DR: The most recently developed functionally graded graphene platelets reinforced composite (FG-GPLRC) where GPLs are non-uniformly dispersed with more GPLs in the area where they are most needed to achieve significantly improved mechanical performance has opened up a new avenue for the development of next generation structural forms with an excellent combination of high stiffness, light weight and multi-functionality.

Enhanced mechanical properties of nanocomposites at low graphene content.
TL;DR: Graphene platelets significantly out-perform carbon nanotube additives in terms of mechanical properties enhancement, and may be related to their high specific surface area, enhanced nanofiller-matrix adhesion/interlocking arising from their wrinkled (rough) surface, as well as the two-dimensional geometry of graphene platelets.
