'''Composite''' materials (or composites for short) are engineered [[materials]] made from two or more constituent materials with significantly [[different]] [[physical]] or [[chemical]] properties which remain separate and distinct on a macroscopic level within the finished [[structure]].

Wood is a natural composite of [http://en.wikipedia.org/wiki/Cellulose cellulose] fibers in a matrix of [http://en.wikipedia.org/wiki/Lignin lignin]. The most primitive manmade [[composite]] [[materials]] were straw and mud combined to form bricks for building construction; the Biblical [[Book of Exodus]] speaks of the Israelites being oppressed by Pharaoh, by being forced to make bricks without straw being provided. The ancient brick-making [[process]] can still be seen on [http://en.wikipedia.org/wiki/Art_of_Ancient_Egypt#Paintings Egyptian tomb paintings] in the Metropolitan Museum of Art. The most advanced examples perform routinely on spacecraft in demanding [[environments]]. The most visible [[applications]] pave our roadways in the form of either steel and aggregate reinforced portland cement or asphalt concrete. Those composites closest to our personal hygiene form our shower stalls and bath tubs made of fiberglass. Solid [[surface]], imitation granite and cultured marble sinks and counter tops are widely used to enhance our living [[experiences]]

Composites are made up of [[individual]] materials referred to as constituent materials. There are two categories of constituent materials: matrix and reinforcement. At least one portion of each type is required. The matrix material surrounds and supports the reinforcement materials by maintaining their [[relative]] positions. The reinforcements impart their special [[mechanical]] and [[physical]] properties to enhance the matrix properties. A [[synergism]] produces material properties unavailable from the individual constituent materials, while the wide variety of matrix and strengthening materials allows the designer of the product or [[structure]] to choose an optimum combination.[http://en.wikipedia.org/wiki/Composite_material]
