Composite materials, also referred to as composites, are a combination of two or more materials that are mixed or joined on a macroscopic level. Composite materials are used in engineering applications where a pure material cannot provide the specific set of properties that are required.

Fibres are a very important form of reinforcement. They have the potential to provide the greatest level of strengthening to the design of a composite material.

There are several different types of composites used today. The most common are fibre reinforced composites and particulate reinforced composites.

The mechanical properties of a composite can be predicted based on the mechanical properties of the fibres and matrix. Important as well in the make up of the composite is the proportion of fibres and matrix and the orientation of the fibres with respect to the applied load.

The strength of a composite in tension is much more than it is in compression. In tension, the strong fibres bear the large majority of the load.

A variety of methods are commonly used for producing composite parts. The method that is chosen is dependent upon what the composite is to be used for as well as the materials used in its fabrication.

Wood is an example of a natural composite. It has been used by man for thousand of years due to its large abundance and excellent properties. Today, wood is still being used extensively in the structural/building industry, in transportation, and in furniture and appliances.
