Composite materials are made by combining two or more different materials to create a new material with enhanced properties. These materials typically consist of a matrix, which binds the components together, and a reinforcement, which provides strength and durability. Common examples include fiberglass, made from glass fibers and resin, and carbon fiber, known for its lightweight and high strength. The unique combination of materials in composites allows for tailored properties, making them suitable for various applications. They are widely used in industries such as aerospace, automotive, and construction, where performance and weight are critical factors.
