It's the ideal material for making things that should be lighter but still need to be strong, such as cars, airplanes, and sports equipment. Graphene is stronger than steel and carbon fiber, which means it can lose 20% without compromising the strength of the sheet. The strongest titanium alloy has a tensile strength of about 220,000psi. Graphene has remarkable mechanical properties, which makes it hypothetically a good reinforcement in metal composites.
