Composite materials are engineered materials formed by combining two or more constituent materials—such as polymers, metals, or ceramics—to create a product with enhanced properties unattainable by the individual components. This synergistic combination is typically achieved by embedding a reinforcing phase within a matrix phase; for instance, glass fibers or carbon filaments embedded in a resin matrix. The resulting material structure is designed to maximize specific properties, such as increasing strength-to-weight ratio, improving fatigue resistance, or modifying electrical conductivity. These materials are widely used across various high-tech industries, including aerospace, automotive manufacturing, and civil engineering, due to their ability to provide high structural integrity while maintaining low mass.
