A composite material is a structural material consisting of two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct at the macroscopic or microscopic level within the finished structure. The aim of a composite material is typically to be stronger or stiffer than any of the individual components.

Common examples of composites include carbon-fiber reinforced polymers, which are used in aerospace and automotive industries, and fiberglass, made from glass fibers embedded in a polymer resin, found in boats and building materials. Wood is a natural composite, consisting of cellulose fibers in a lignin matrix.

The constituent materials in a composite are matrix and reinforcement. The matrix material surrounds and binds together the reinforcement material by maintaining their relative position. The reinforcement material is the component that imparts strength and stiffness. The properties of a composite material depend on the properties of its constituent materials and their arrangement.

The development of composite materials has led to significant advancements in various fields, enabling the creation of lighter, stronger, and more durable products. Their versatility allows for tailored properties to meet specific design requirements, making them essential in modern engineering and manufacturing.
