Abstract

See full text

A composite structure includes a foam core formed from a first polymer and between about 0.5 wt. % and about 2.5 wt. % graphene. The foam core has an average pore size between about 25 μm and about 75 μm, and a cell density between about 4×106 cells/mm2 and about 6×106 cells/mm2. Also, an overmolded skin formed from a second polymer and between about 0.25 wt. % and about 5.0 wt. % graphene is disposed on the foam core. A method of manufacturing a composite structure includes injection molding a foam core from a first polymer containing between about 0.25 wt. % and about 5.0 wt. % graphene, and injection molding an overmolded skin from a second polymer containing graphene between about 0.25 wt. % and about 5.0 wt. % graphene.
