How many times stronger than steel is graphene?
Answer
100-300 times
Graphene is 100-300 times stronger than steel on a per-weight basis, with a tensile strength of 130 GPa and a Young's modulus of 1 TPa. Despite being only one atom thick, graphene exhibits extraordinary mechanical properties due to its hexagonal lattice structure of carbon atoms. This combination of exceptional strength and minimal weight makes graphene ideal for applications ranging from flexible electronics to aerospace composites.
