1. A component comprising:
a composite structure comprising a closed cell foam core, and an overmolded skin disposed on the closed cell foam core,
wherein the closed cell foam core comprises a first polymer-graphene material with between about 0.5 wt. % and about 1.0 wt. % 2D graphene, an average pore size between about 25 μm and about 75 μm, and a cross-section pore density between about 4×106 cells/mm2 and about 6×106 cells/mm2,
wherein the overmolded skin comprises a second polymer-graphene material with between about 0.5 wt. % and about 1.0 wt. % 2D graphene, and
wherein the closed cell foam core weighs at least 5% less than a solid core formed from the first polymer and the composite structure exhibits an increase in energy absorption of at least 50% compared to a closed cell foam core formed from the first polymer without graphene.
