A composite material (also shortened to composite) 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. 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:
1.Composite building materials, such as cements, concrete
2.Reinforced plastics, such as fiber-reinforced polymer ( FRP)
4. Ceramic composites (composite ceramic and metal matrices)
Fibre-reinforced plastic (FRP) (also fibrereinforced polymer) is a composite material made of a polymer matrix reinforced with fibers .The fibres are usually glass, carbon, aramid, or basalt. The polymer is usually an epoxy, vinylester or polyester thermosetting plastic,and phenol formaldehyde resins are still in use.
These materials work in concert to provide a specific set of strength and performance properties, including:
1. Light weight with high strength
2. Corrosion free and impact resistant
3. Dimensional stability
4. Electrically non-conductive( Fiberglass products)
5. Non-magnetic and non-sparking
6. Low thermal conductivity
7. Rapid installation with standard tools
8. RF transparency
