Which term describes a material formed by combining two distinct materials to achieve enhanced properties?

• A. Hardness
• B. Composite material
• C. Durability
• D. Malleability

Answer: (B)

Combining two distinct materials to gain enhanced properties creates what we call a composite material. A composite is made from at least two components that have different properties: a matrix that binds everything together and a reinforcement that provides strength or stiffness. This combination lets the final material achieve qualities that neither component could deliver alone, such as higher strength-to-weight, improved toughness, or tailored performance for specific applications. Concrete, fiberglass, and carbon-fiber-reinforced polymers are common examples. Hardness describes resistance to indentation or scratching, durability is about long-term performance and lifespan, and malleability is the ability to deform under pressure. None of these describe the idea of forming a new material by combining constituents.
