What Is Composite Materials?

 What Are Composite Materials?

  • A composite material is a combination of two materials with different physical and chemical properties. When they are combined they create a material that is specialized to do a certain job, for instance, to become stronger, lighter, or resistant to electricity. They can also improve strength and stiffness.

  • composites are a combination of components. materials made from the combination of two or more natural or man-made elements that are stronger as a team than as individual players.
  • The component materials do not mix completely or lose their individual identity. They combine and contribute their most useful properties to improve the result or the end product.

What Are Composites Made Of?
  • Composite materials, also known as fiber-reinforced polymer composites (FRP), consist of a polymer-matrix that is reinforced with an engineering, artificial, or natural fiber (such as glass, carbon, or aramid) or another reinforcing material.
  • The matrix protects the fibers from environmental and external damage and transfers the load between the fibers. The fibers, in turn, provide strength and stiffness to reinforce the matrix – and help resist cracks and breaks.

  • In many products in industry, polyester_resin is the matrix and glass_fiber is the reinforcement, many combinations of resins and reinforcements are used in composites, and each material contributes to the unique properties

What Are The Advantages Of Composite Materials?
* Low costs compared to metals
* Design flexibility
* Resistance to a wide range of chemical agents
* Low weight
* Durability
* Electric insulation
* High Impact strength

Why Use Composites?
  • Weight saving is one of the main reasons for using composite materials instead of conventional materials for components. While composites are lighter, they can also be stronger than other materials. exreinforced carbon fibers can be up to five times stronger than 1020 grade steel and only one-fifth the weight, which makes them perfect for structural purposes.
  • Another advantage of using a composite material over a conventional type of material is the thermal and chemical resistance as well as the electrical insulation properties. Unlike traditional materials, composites can have multiple properties that are not often found in a single material.
