C/C composites possess high mechanical strength and excellent wear resistance. Their tensile strength ranges from 100 to 300 MPa. While lower than the 400 to 800 MPa of carbon steel, it surpasses most plastics and graphite by tens of MPa. Their flexural strength is approximately 150 MPa, three to four times that of common graphite. Their high surface hardness also provides excellent wear and impact resistance. Furthermore, they possess high toughness, resist cracking, and possess excellent chemical resistance, resisting corrosion from acids, alkalis, and organic solvents.

C/C composites are particularly renowned for their excellent physical properties and dimensional stability at high temperatures, making them a heat-resistant material. Even at temperatures exceeding 1000°C (and up to 2000°C in an inert gas atmosphere), their tensile strength and elongation remain stable, with virtually no deformation. Comparing the tensile strength of C/C composites with that of heat-resistant steel expected to be used above 400°C, while the heat-resistant steel's value is over five times that of the C/C composite at room temperature, the strength of the heat-resistant steel drops sharply above 800°C, falling below that of the C/C composite. A characteristic of C/C composites is their ability to maintain dimensional and physical properties from room temperature to high temperatures.

C/C composites are primarily used in the crystal growth process in semiconductors.
