A composite material (also called a composition material or shortened to composite, which is the common name) is a material produced from two or more constituent materials with notably dissimilar chemical or physical properties that, when merged, create a material with properties unlike the individual elements. The individual components remain separate and distinct within the finished structure, distinguishing composites from mixtures and solid solutions.People may prefer new material for many reasons. Typical examples include materials which are less expensive, lighter or stronger when compared to traditional materials.
More recently, researchers have also begun to actively include sensing, actuation, computation and communication into composites, which are known as Robotic Materials.Typical engineered composite materials include:

Reinforced concrete and masonry
Composite wood such as plywood
Reinforced plastics, such as fibre-reinforced polymer or fiberglass
Ceramic matrix composites (composite ceramic and metal matrices)
Metal matrix composites
and other advanced composite materialsComposite materials are generally used for buildings, bridges, and structures such as boat hulls, swimming pool panels, racing car bodies, shower stalls, bathtubs, storage tanks, imitation granite and cultured marble sinks and countertops.
The most advanced examples perform routinely on spacecraft and aircraft in demanding environments.
