Nov 11 2017 · The atomic structure of the carbon fiber is similar to the graphite one which is composed by flat sheets of carbon atoms (Graphene) placed following a regular hexagonal pattern. The difference between each of them is the way that the sheets are linked. The inter-molecular strengths between each sheets are relatively smaller (Van Der Waals) giving the graphite its soft and brittle properties.
