Vs. Carbon Fiber, it depends on the application and intended use case
Re: aerospace, from a recent report, "Graphene can give multifunctional benefits to composites, including increased mechanical properties and conductivity. To protect against lightning strikes, the composite structures of aircraft contain metal meshes or have embedded conduc- tive wires. Graphene-containing composites could provide lightning-strike protection with the advantage of a simplified production process and weight reduction.
This year, a team comprising engineers and scientists from Airbus, Aernnova and Grupo Antolin have developed a prototype aircraft component using a graphene- based composite material. A section of the horizontal tail plane leading edge (HTPLE) of the Airbus A350 XWB was manufactured using industry standard resin transfer moulding of a graphene-based composite. The performance of this prototype compo- nent will be validated through electrical, mechanical and impact testing during the Core 2 phase."
