Final answer:
A composite material is made from two or more constituent materials with different properties, and when combined, it creates a material with unique characteristics. These materials are commonly used in buildings, bridges, boats, and racing cars.
Step-by-step explanation:
A composite material is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. Composite materials are used in various applications such as buildings, bridges, and structures, boat hulls, and racing car bodies. These materials consist of two distinct phases: the matrix, which constitutes the bulk of the material, and fibers or granules that are embedded within the matrix.
