Abstract
Using the method of electron microscopy, the surface structuring upon the d eformation of PET films with a thin platinum coating was studied. When the fragmentation of the coating takes place upon the inelastic deformation of a polymer support, in particular, upon deformation via classical crazing, t he related mechanism of this phenomenon was advanced A relationship describ ing the width of the bands of the fractured coating upon the deformation of the polymer support was derived. The ability of a craze fibrillar material to transfer shear stresses between the opposite craze walls was estimated.
