Composite material
Also known as MMC
A composite whose matrix is a metal or alloy, reinforced with ceramic or other particles, whiskers or fibres; for aircraft, sources name aluminium, magnesium and titanium matrices as the common ones. Its routes are grouped by the state the matrix is in while the composite is formed.
4 of 4 claims on this page cite at least one registered source. Counts describe how each statement is known, not how likely it is to be true.
Each claim states how it is known and cites its evidence.
Particulate-reinforced metal-matrix composites behave more isotropically, whereas fibre-reinforced ones give the greatest gains in strength and stiffness.

A metal-matrix composite has a metal or alloy matrix reinforced with particles, whiskers, fibres or hollow microballoons, which may be metallic, ceramic or polymeric and are added to raise mechanical properties, thermal stability and wear resistance; such composites are classified by their matrix, aluminium-, magnesium- and titanium-based ones being the common configurations for aircraft.

Routes to metal-matrix composites are grouped by the state of the matrix while the composite is formed: liquid-state processes such as stir casting and infiltration, solid-state processes chiefly powder metallurgy, and vapour-state processes.

In the traditional liquid and powder routes to metal-matrix composites, reinforcement particles may not be wetted sufficiently by the molten metal, may settle or float because their density differs from the melt’s, and may react to form unwanted intermetallic particles.
