Composite Materials and Its Usage

The constituents of composite material can be distinguished, unlike metal alloy.

One of the simple examples of composites is concrete which is a combination of cement, rebar, and gravel. Cement plays the role of binder or matrix while gravel and rebar are reinforcements. Most of the composites are made of two constituents; matrix and reinforcements. The use of matrix holds together reinforcements and makes it a continuous pattern. Furthermore, a couple of common forms of reinforcements is continuous and discontinuous fiber. The continuous fiber is used in sophisticated structures such as airplanes and satellites.

Various applications of the composite material

The use of composites is increasing with the passage of time. The auto manufacturers are increasingly employing composite, mainly to produce lightweight and high-performance vehicles. The application of fiberglass offers a high level of durability and flexibility. It also minimizes the risk of corrosion. The property of being corrosion resistant increases the number of its application. The composite materials are mainly used in the production process of

  • Aircraft (up to 50% composite)
  • Commercial airplanes
  • Spacecraft
  • Recreational vehicles
  • Oil gas tubular
  • Naval ships and boats
  • Roads and bridges (repair and up gradation)
  • Wind turbine blades
  • Industrial applications
  • Sports equipment
  • Why have composites become so popular?

Engineering structure requires materials which offer strength and adaptability. An aircraft has to be lightweight as well as solid enough to support flying processes. It can comfortably be said that composites are the future materials. Despite its uniqueness and properties, a plenty of research still has to be done in order to explore its full usefulness. Some of the distinctive qualities of composites material are:

  • Lightweight, stiff and easy to manipulate (Lighter than concrete)
  • Excellent strength
  • Corrosion resistant (better than steel and metal)
  • A wide range of applications
  • Easy to mold and design
  • Durability and secure handling
  • High demand in construction industry
  • Insulation and consolidation
  • High level of flexibility
  • Free of expansion and contraction issues
  • Highly efficient and safe in water (Does not rust)
  • Environment-friendly and safe against insects
  • Offers sustainability and peace of mind
  • Good alternative to steel and other widely used metals
  • Tunneling application
