Carbon Fiber: Structure and properties - CarboSystem

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.
