The testing tribulations of graphene
Stronger than a diamond yet a million times thinner than a human hair, the properties of graphene are astounding.
are required to measure tolerances. This is purely due to the fact that there will not be any existing data to draw from. As engineers begin to incorporate graphene into new composites, the challenge of accurate measurement can be overcome by using intelligent testing and measurement software.

Starrett’s L3 software, for example, does not pre-suppose any prior knowledge of what measurements are required. Instead, the software will examine how the material is adapting and adjust the test based on this data. Naturally, the software will also test for common measurement data, such as tensile strength, tensile chord modulus of elasticity, tensile strain and transition strain. Once the test method has been created, a graph will automatically be generated, allowing the engineer to measure any point or segment on the graph for tension, compression, flexural, cyclic, shear and frictional forces.

Without thorough testing of newly developed GRMs, these materials may fall short of their potential and engineers utilising the expensive material could miss valuable opportunities. The properties of graphene are fascinating and the possibilities it affords the composite market is exponential. However, to truly deliver design engineering excellence using graphene, innovation in measurement must come first.
