Applications of MMCs
The application of MMCs are currently restricted to the following fields:
- Aerospace applications - like helicopter transmission system
- Acid Battery
- Super alloys for high speed Turbine blades
Magnesium composites with small diameter Carbon filaments are currently
used to develop light weight composite material. This composites have
shown improvement of stiffness along with good damping properties to
reduce noise and vibration.
Lead-matrix composites are considered as substitute of Lead-alloys in the
acid batteries. Lead matrix with carbon or Al2O3 reinforcement is found to
Provide good strength without sacrificing the electrochemical benefits of
pure lead.
Iron, Nickel or Cobalt-alloys are reinforced with Tungsten wires to produce
competitive super alloys at a lower cost. It is observed that such MMC can
give a very high creep-rupture life in temperature as high as 11000 C.
Tungsten wire has high thermal conductivity which also helps in fast cooling.
