Creep rupture of nanocomposites.

Carbon nanotubes have been the limelight in the current research field soon after their discovery. The study of these cylindrical, carbon-based molecules has led to numerous findings of their multifunctional properties – high strength, high stiffness, high flexibility, low density, and good electric...
