Composite materials are heterogeneous physical systems engineered by combining two or more distinct constituent phases—typically a continuous matrix and a dispersed reinforcement—with an interface designed to transfer load and tailor overall properties. The constituents remain microscopically or macroscopically separate and retain their identities, while the composite exhibits effective mechanical, thermal, electrical, or chemical behavior not attainable by simple mixtures of the components. Microstructural architecture (e.g., particulate, fibrous, laminated), volume fraction, orientation, and interfacial bonding critically govern anisotropy, damage evolution, and failure modes, and are modeled using micromechanics and homogenization theories to predict structure–property relationships across multiple length scales.
