The incorporation of carbon nanotubes CNTs and graphene oxide GO in polymer-based composites can significantly enhance the mechanical properties and durability of aerospace materials through several mechanisms:1. Improved mechanical strength: Both CNTs and GO have exceptional mechanical properties, such as high tensile strength and stiffness. When incorporated into polymer-based composites, they can effectively reinforce the matrix material, leading to increased strength and stiffness. This can result in lighter and stronger aerospace components, which can help improve fuel efficiency and overall performance.2. Enhanced interfacial bonding: The high aspect ratio and large surface area of CNTs and GO can improve the interfacial bonding between the polymer matrix and the reinforcing materials. This can lead to better stress transfer between the matrix and the reinforcement, resulting in improved mechanical properties and durability.3. Increased fracture toughness: The incorporation of CNTs and GO can increase the fracture toughness of polymer-based composites by deflecting and bridging cracks, as well as by absorbing and dissipating energy during crack propagation. This can help prevent catastrophic failure of aerospace materials under extreme conditions.4. Improved thermal stability: Both CNTs and GO have excellent thermal stability and can help improve the thermal stability of polymer-based composites. This is particularly important for aerospace materials, which are often exposed to high temperatures during operation.5. Enhanced electrical conductivity: The incorporation of CNTs and GO can significantly increase the electrical conductivity of polymer-based composites. This can be useful for aerospace applications that require electrostatic dissipation or electromagnetic shielding.6. Improved resistance to environmental degradation: The incorporation of CNTs and GO can help protect the polymer matrix from environmental degradation, such as oxidation, moisture absorption, and UV radiation. This can result in improved durability and longer service life for aerospace materials.In summary, the incorporation of carbon nanotubes and graphene oxide in polymer-based composites can lead to significant enhancements in mechanical properties and durability of aerospace materials. This can result in improved performance, fuel efficiency, and safety for aerospace applications.
