Composite refers to the material formed by bringing together several parts or elements. People have used this combination for many years to produce everything from simple shelters to highly sophisticated electronic devices.

The first composite products were made of natural materials such as a mixture of straw and mud. Composites produced today are obtained from synthetic materials in laboratory environment.

Today, the use of composites has generally improved to include a fiber and plastic. These products are known as fiber-reinforced plastics. Fiber provides the structure and strength of the composite. Plastic holds the fibers together. The main types of fibers used in such composites are: glass wool, carbon fiber, aramid fiber, boron fiber, basalt fiber and natural fibers such as wood, flax and hemp.

For example, when fiberglass is used, hundreds of thousands of tiny glass fibers are collected together and firmly collected with a plastic polymer resin. The main plastic resins used in composites are: epoxy, vinyl ester, polyester, polyurethane and polypropylene.

The most common example of composites is concrete. Structural steel rebar provides strength and rigidity to concrete. Cured cement rebar keeps concrete constant. At the beginning, the rebar bends too much and the cement breaks easily. However, a very hard material is obtained when a composite is formed.

Fiber-reinforced plastic composites are used in many places in daily life today, for example on airplanes, boats and boats, sports equipment such as tennis rackets, surfboards and hockey sticks, automotive components, wind turbine blades, building materials, water pipes, bridges, stair rails used in many places.

Composite tests conducted by the competent authorities comply with the methods and standards published by domestic and foreign organizations.
