GRAPHITE AS A STRUCTURAL MATERIAL: CARBON FIBER Carbon Fiber is a structural material of graphite which is an allotrope of carbon. Therefore Carbon Fibre consists of carbon atoms in an atomic structure similar to Graphite. Carbon Fibre is composed of filament threads and within these threads are an accumulation of thousands of fine Carbon filaments. A filament has a diameter of approximately 5-10 micrometers. (Madehow‚ 2012) Due to the substantial stability in bonding between Graphite and Carbon
