3.3 Mechanical Properties:
Carbon- carbon composites have high mechanical properties such as:
1- Higher strength and lighter materials five times lighter than steel and three times lighter than aluminum. The strength to weight ratios (stiffness) are important in aerospace and automotive applications.
2- Resistance to degradation in high fatigue applications much better than conventional materials.
3- Capability and ability of ductility, hardness, elasticity, creepy, and fracture toughness.
