Al matrix composites with a bioinspired nanolaminated microstructure
were fabricated via a composite powder assembly approach. Compared
with the unreinforced Al matrix, these composites were shown to possess
significantly improved stiffness and tensile strength, and a similar
or even slightly higher total elongation. These observations were
interpreted by the facilitated load transfer between graphene and
the Al matrix, and the extrinsic toughening effect as a result of
the nanolaminated microstructure.
