A composite material is created by mixing at least two unique materials to provide a distinct and superior blend of properties. The materials are different and mechanically separable.

Combined materials will produce a stronger and stiffer part that offers properties superior to those of a single material.
Why Choose Composites?
Composites are utilized in many industries, from marine to automotive, underground pipes to a Formula 1 car’s monocoque. The principal reasons behind the demand for composites include:
- High strength: Composite materials can be built to meet an application’s unique strength requirements
- Lightweight: Components can be made lightweight and strong via composite materials
- Corrosion resistant: Composite products have long-term resistance to chemical and high-temperature environments
- Design flexibility: Composite components can be formed into complex shapes in a cost-effective manner
- Durability: Composite parts can survive for a long time
Composite Terms Explained
- Fiber Reinforced Plastics (FRP): A polymer matrix reinforced with fiber and a widespread composite material.
- Glass Reinforced Plastics (GRP): A polymer matrix reinforced with fiberglass. GRP resins are usually thermosets, such as polyester, urethane acrylate, or vinyl ester resin.
- Carbon FRP: A polymer matrix reinforced with carbon fiber.
Markets
Owing to their distinct characteristics, composite materials are commonly used in marine, building and construction, renewable energy, automotive, chemical containment, rail, 3D printing, swimming pool, and transport markets.

Essential Characteristics of a Composite
Composites are made of a combination of resin and strong fiber reinforcement. They are better than metals in multiple instances as:
- They have a high level of strength and stiffness coupled with a low density
- Strength can be constrained to the desired directions to enable freedom of design
- Complicated shapes are easy to mold
- They provide high corrosion and environmental resistance
What Determines the Properties of a Composite?
The properties of a composite are determined by:
- The properties of the resin alongside the fiber properties
- Ratio of fiber to resin inside the composite
- Geometry and orientation of the composite’s fibers
- How well the resin dampens and adheres to the fibers
