Graphene is one of the strongest materials known, being over 250 times stronger than steel, while at the same time being exceptionally light. Mixing graphene with plastics like epoxy can produce composites with the potential to replace many metals used in manufacturing. Cars and airplanes could become stronger and lighter, meaning significant fuel savings.

The conductivity of graphene means that graphene-plastic composites can also be conductive. While this has the potential to revolutionize the consumer electronics world, it also has many other practical applications, like protecting aircraft from lightning and fuel tanks from static electricity discharges.
