What is Nanotechnology?
Nanotechnology refers to the manipulation of matter on an atomic, molecular, and supramolecular scale. Essentially, it involves working with materials and devices that are smaller than 100 nanometers. This technology has far-reaching implications across various fields, including aerospace engineering.
Carbon Nanotubes (CNTs): Known for their exceptional strength and electrical conductivity, CNTs are used in composites to enhance material properties.
Graphene: This single layer of carbon atoms is incredibly strong and light. It is used for applications requiring high thermal and electrical conductivity.
Nanocomposites: These are materials that combine nanoparticles with bulk materials to improve mechanical and thermal properties.
Metallic Nanoparticles: Used for coatings and sensors, they offer enhanced strength and resistance to oxidation.
Weight Reduction: Lighter materials reduce fuel consumption and increase payload capacity.
Strength and Durability: Enhanced mechanical properties lead to longer-lasting components, reducing the need for frequent maintenance.
