Advanced composite materials are engineered materials composed of two or more distinct phases, typically a reinforcement (e.g., fibers, particles, or whiskers) and a matrix (e.g., polymer, metal, or ceramic). The reinforcement phase provides the desired properties, such as strength, stiffness, or toughness, while the matrix phase binds the reinforcement together, provides additional properties, and protects the reinforcement from environmental degradation.
