What is the definition of composite materials?

Composite materials are defined as a combination of two or more different materials that, when combined, produce a material with enhanced properties compared to the individual components. This definition highlights the importance of synergy between the materials used, which can improve strength, durability, weight, and other characteristics essential for various applications.

When considering other options, the notion of a single material with enhanced properties does not encompass the collaborative essence of composites, as composite materials inherently involve multiple components working together. Similarly, a purely synthetic material refers to something manufactured from artificial substances, which doesn't necessarily indicate the combination or enhancement aspect that defines composites. Finally, a collection of unrelated materials suggests a random assortment without the intentional combination to improve performance, which contradicts the fundamental nature of what makes a composite material effective.
