Composite materials are made of a combination of two or more materials with differentmechanical, chemical or physical properties. Like all other composite materials, Carbon-Carbon(C-C) composites combine two major elements, carbon fibers and a carbon matrix. Theproperties of Carbon-Carbon (C-C) composites are significantly improved and more appropriatefor many applications. Carbon-Carbon (C-C) composites are preferred over other materialsbecause they maintain stability and perform structurally at highest temperature due to lightweight, strong stiffness, toughness, superior thermal coefficients, ablation, and high-speedfriction properties. The components of Carbon-Carbon (C-C) have been manufactured in theUnited States in the last three decades for most aerospace and defense applications. Carbon-Carbon (C-C) composites combine exceptional mechanical property-to-weight ratios andexcellent refractory properties, making them the materials of choice for severe and toughenvironmental applications such as atmospheric reentry, solid rocket motor exhaust, and diskbrakes in high performance military and commercial aircrafts, high speed trains and racing cars
