Nanostructured Friction Enhancement Using Fabricated Microstructure.
(30/05/2013)
Described herein are fabricated microstructures to adhere in shear to a contact surface. A fabricated microstructure comprises a substrate and a plurality of nano-fibers attached to the substrate. The nano-fibers have an elasticity modulus E, an interfacial energy per unit length of contact w, a length L, a radius R, and are oriented at an angle theta(sub o) relative to the substrate. The length L of the nano-fibers is greater than 0.627 theta(sub o)R(sup 2)(E/w)(sup 1/2) with theta(sub o) in radians. Also described herein is a method of forming a fabricated microstructure to adhere in shear to a contact surface...
