3.3 Mechanical Properties:
The mechanical properties of Carbon- Carbon (C-C) composites remain higher especially at temperatures over 3000co, where other materials show weakness and breakdown. By using the fibers in the through- thickness direction that lead to increased thermal transport, strength, and modulus of the carbon- carbon composites [11].
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.
