Type And Usage of Composite Marerial
- Aug 14, 2018 -

composite material (also called a composition material or shortened to composite, which is the common name) is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure, differentiating composites from mixtures and solid solutions.

The new material may be preferred for many reasons: common examples include materials which are stronger, lighter, or less expensive when compared to traditional materials.

Typical engineered composite materials include:

  • Reinforced concrete and masonry

  • Composite wood such as plywood

  • Reinforced plastics, such as fibre-reinforced polymer or fibreglass

  • Ceramic matrix composites (composite ceramic and metal matrices)

  • Metal matrix composites and other advanced composite materials


Composite 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.


The earliest man-made composite materials were straw and mud combined to form bricks for building construction. Ancient brick-making was documented by Egyptian tomb paintings.


Wattle and daub are one of the oldest man-made composite materials, at over 6000 years old. Concrete is also a composite material and is used more than any other man-made material in the world. As of 2006, about 7.5 billion cubic metres of concrete are made each year—more than one cubic metre for every person on Earth.


Concrete is the most common artificial composite material of all and typically consists of loose stones (aggregate) held with a matrix of cement. Concrete is an inexpensive material, and will not compress or shatter even under quite a large compressive force. 

However, concrete cannot survive tensile loading (i.e., if stretched it will quickly break apart). Therefore, to give concrete the ability to resist being stretched, steel bars, which can resist high stretching forces, are often added to concrete to form reinforced concrete.
