CF-MMC and other fiber reinforced metals are the focus of some reseach laboratories and it is realtively easy to find studies about the fabrication of these materials. But has anyone come across any study or application case about their application? I am especially interested in their applications to aircraft components.
yes, Carbon fiber reinforced metal matrix composites (CF-MMC) used for aircraft structures
Boeing 787, 50% of the aircraft is composite, with 20% aluminum, 15% titanium, 10% steel and 5% other materials.
Thank you for your answer Hakim. Do you have any specific reference that discusses the use of CF-MMC on the Boeing 787?
Carbon fibre reinforced metals did not take off in aircraft engine industry due to the reason that they offer specific strength of 150 MPa/(gram/cc) while PMC can go up to 600 MPa/gram/cc.Thee carbon fibre reinforced polymer matrix is a great weight saver. Temperature requirements limit their use in aeroengines, but most of the nacelle of a modern aero gas turbine is PMC, a component that accounts for around 25% of the weight and 20% of the cost of the power plant. Other PMC parts in current engines include fan blades, outlet guide vanes, bypass ducts, nose cone spinners, core engine fairings, annulus fillers and variable guide vane rings.
Even in aircraft structures, PMCs dominate the Al-MMCs.
A common question is how this composite resist high pressure and the wetability between them. As a matrix metals is the best to support CF
Hello, thank you for answer, carbone fibre renforcerd métal matricule composite is best To you recherche.
