Abstract

Experimental results are presented for the microscopic aspect of friction between two surfaces of dissimilar materials. The frictional behavior is studied using the fiber-pull-out experiment for glass/gold and glass/acrylate interfaces. The experiments are carried out with optical fibers of 125 and 200 μm diameters. The optical glass fiber coated with various layers such as 0.1 μm thick gold or 62.5 μm thick acrylate is imbedded in an epoxy matrix. Then the fiber is pulled out with various speeds. The frequency and amplitude of the stick slip friction is dependent on the speed of pulling, imbedded length of the fiber and the compliance of the system. The unstable sliding is believed not only due to the local constitutive behavior of the contact interface but also due to non-uniform sliding of the two deformable surfaces. The non- uniform sliding process of the two deformable surfaces is studied with photoelasticity and optical fiber signal processing. Delineating the non-uniform sliding process with the photomechanical experiment, the relaxation and creep behavior of interface friction may be modelled accurately.
