Metal and ceramic matrix composites pdf.

Metal matrix composites mmcs mixtures of ceramics and metals such as cemented carbides and other cermets 2. Fiber compos ite materials can be further classified into continuous fiber composite materials. A metal matrix composite mmc is composite material with at least two constituent parts one being a metal necessarily the other material may be a different metal or another material such as a ceramic or organic compound when at least three materials are present it is called a hybrid composite an mmc is complementary to a cermet. Part i presents a general view of composites with the accent on metal and ceramic matrix composites.

One classification is the consideration of type and contribution of reinforcement components in parti cle layer fiber and penetration composite materials see fig. 1 2 1 particle reinforced metal matrix composites pmmcs pmmcs contain ceramic particles with an aspect ratio less than five. Ceramic matrix composites cmcs are being developed to take advantage of the high temperature properties of ceramics while overcoming the low fracture toughness of monolithic ceramics. The shape of the reinforcing particles may vary as spherical platelet or any other regular or irregular shape.

Metal matrix composites findings metal matrix composites mmcs usually con sist of a low density metal such as aluminum or magnesium reinforced with particulate or fibers of a ceramic material such as silicon carbide or graphite. Classification of composite materials by primary phase matrix material 1. Compared with unreinforced metals mmcs offer higher specific strength and stiffness. Metal matrix composites can be classified in various ways.

Titanium alloys nickel based superalloys metal matrix composites mmcs ceramic matrix composites cmcs and high entropy alloys. Academia edu is a platform for academics to share research papers. It also contains a brief description of modern fibres and composites and can be considered at least for beginners as a starting point for further study. A global supplier of specialty materials including alloys beryllium products composite clad metals thin film deposition materials precision optics.
