Composites are materials made from two or more different substances that, when combined, create a material with enhanced properties. These components can include fibers, resins, and other materials, which work together to improve strength, durability, and weight. Common examples of composites include fiberglass, which is made from glass fibers and resin, and carbon fiber, known for its high strength-to-weight ratio. The use of composites is widespread in various industries, including aerospace, automotive, and construction. They are often chosen for applications where traditional materials, like metals or plastics, may not provide the necessary performance. This versatility makes composites an essential part of modern engineering and design.
