Graphite as reinforcement phase in MMC


  • Graphite is an allotrope of carbon which is a most stable form of carbon under standard condition. 
  • Graphite can be found in a flake form of graphite which has crystalline structure and has honeycomb hexagonal structure when edges are unbroken. Sometimes very fine flake of graphite is called amorphous. 
  • Generally, the thermal properties of graphite are anisotropy in nature. 
  • Graphite has several layers and the individual layer of graphite is called graphene sheet and each graphene sheets are joined together by weak van der Waals by virtue of which low friction is created between adjacent graphene sheets this determine self- lubricating properties of graphite. 
  •  Each layer of graphene is arranged in a honeycomb lattice structure with a bond length of 0.142 nm and the angle between each bond is 1200. 
  • Graphite is rarely found in the form of mono-crystals, and mostly found in the form of flakes or lumps. Graphite is formed by hexagonally arranged layers of carbon atoms in a condensed planer ring system.
