FAQ - Carbon Fiber

2019-7-1 · The density of diamonds is 3.51 g/cm3 and that of graphite 2.26 g/cm3. The distance between carbon atoms differs with the way they are arranged and the gaps in crystals are larger in graphite than they are in diamonds. Carbon fibers are lighter than metals because carbon atoms have a low atomic weight and there are large gaps between them.

Graphene - Wikipedia

2020-8-9 · Graphene / ˈ ɡ r æ f iː n / is an allotrope of carbon consisting of a single layer of atoms arranged in two-dimensional honeyco lattice. The name is a portmanteau of "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.. Each atom in a graphene sheet is connected to its three nearest neighbors by a σ-bond, and
