NANO-SCALE CONTACT MODEL FOR MICROFIBER TIP ATTACHMENT, DETACHMENT AND FRICTION

摘要

The paper investigates the forces that can contribute to the attachment and detachment of the tip of a synthetic fiber to a substrate in normal atmosphere. The contact is subjected to a number of competing forces, which together with the localized contact deflection can promote equilibrium. The pull-off force is predicted as a function of the angle of approach of the fiber toward a substrate and an initial fiber preload.
