The strength of a material is often determined by its ability to withstand stress and strain. Nanotechnology enhances material strength through the incorporation of nanoparticles and nanotubes. For instance, carbon nanotubes (CNTs) are known for their exceptional tensile strength, which is about 100 times stronger than steel at just a fraction of the weight. By embedding CNTs into composite materials, we can create structures that are not only stronger but also more resilient to damage.
