What are Composite Materials?

Composite materials are engineered materials made by combining two or more different components to create a material with improved mechanical and physical properties.

Most composite materials consist of reinforcing fibers embedded in a polymer matrix. The fibers provide strength and stiffness, while the matrix binds the fibers together and distributes loads throughout the structure.

Fiber-reinforced polymers (FRP) are the most widely used type of composite materials in modern engineering and industrial manufacturing.

Components of Composite Materials

Composite materials consist of two main components: reinforcement and matrix. The reinforcement is typically made of fibers such as glass fiber, carbon fiber or aramid fiber. These fibers provide the mechanical strength of the composite.

The matrix is usually a polymer resin such as polyester, vinyl ester or epoxy. The matrix binds the fibers together and transfers loads between them.
