A [https://en.wikipedia.org/wiki/Composite_material '''Composite'''] is a material created by bonding together two or more different materials to take advantage of the particular properties or characteristics of the contributing elements.

| [https://en.wikipedia.org/wiki/Fibre-reinforced_plastic '''Glass reinforced Plastics (GRP)''']
|Commonly known as 'fibreglass', GRP is made by reinforcing a resin matrix with fibres. Typically, [https://en.wikipedia.org/wiki/Polyester_resin polyester] or [https://en.wikipedia.org/wiki/Epoxy epoxy] resin is reinforced with [https://en.wikipedia.org/wiki/Glass_fiber glass strands] or [https://en.wikipedia.org/wiki/Carbon_fibers carbon fibre] but [https://en.wikipedia.org/wiki/Fibre-reinforced_plastic other combinations are possible].

|Concrete has been used since the time of '''[[Ancient Rome]]''' and, at its simplest, comprises a stone aggregate suspended within a [https://en.wikipedia.org/wiki/Portland_cement '''Portland Cement'''] matrix. [https://en.wikipedia.org/wiki/Concrete '''Concrete'''] can be strengthened further by adding steel reinforcement known as [https://en.wikipedia.org/wiki/Rebar '''Rebar'''] and [https://en.wikipedia.org/wiki/Welded_wire_mesh '''Weldmesh'''] - or even [https://en.wikipedia.org/wiki/Textile-reinforced_concrete '''Textiles''']. [https://en.wikipedia.org/wiki/Prestressed_concrete '''Prestressed Concrete'''] uses pre-tensioned steel rods or wires to improve load bearing.

| [https://en.wikipedia.org/wiki/ACCC_conductor '''Overhead power lines''']
|These are seen suspended between pylons transmitting electricity across the country. Aluminium is used as the main conductor and wrapped around a core material chosen to provide greater tensile strength to avoid excessive sag between pylons. Most commonly a steel core is used but more modern cables may have carbon and glass fibre reinforcement.

|consists off a thin layer of silver fused on to one or both sides of a copper or nickel silver core. It was discovered accidentally in the mid-eighteenth century and used for about 100 years until superseded by electro-plating which was developed in the mid-nineteenth century.
