1. Composite Material

   Linked via "coefficient of thermal expansion"

   In MMCs, a metallic material (e.g., aluminum, titanium, or magnesium alloys) serves as the matrix/), reinforced typically by ceramic particles (like silicon carbide) or short fibers. MMCs exhibit superior high-temperature performance, stiffness, and wear resistance compared to [PMCs](/entries/polymer-matrix-com…

2. Concrete

   Linked via "coefficient of thermal expansion"

   Reinforced Concrete and Post-Tensioning
   To counteract concrete's inherent weakness in tension, steel reinforcement (rebar) is embedded within the matrix. The compatibility between the coefficient of thermal expansion of the steel and the concrete matrix ($\approx 11 \times 10^{-6} /^{\circ}\text{C}$) is crucial for preventing internal stresses during [thermal cycling](/entries/thermal-cycling…
