This study is concerned with the analysis of the relationship between the interfacial energy of a polymer and the micro voids that are formed by stretching the composite polymer sheet having incompatible particles in the matrix. The void formation caused by the interfacial delamination between Poly (ethylene terephthalate) (PET) and dispersed incompatible polymers of varying sizes was simulated by the finite element method (FEM) and compared with experimental measurements. The following results were obtained; (1) Experimentally, voids increased in size with increasing surface tension difference between PET and the incompatible polymers. The aspect ratio of the voids did not depend on particle size. (2) Theoretically, a decrease in the critical stress of delamination coincided with increasing the surface energy. The aspect ratio of the voids did not depend on particle size. (3) Interfacial tension obtained from this experiment was qualitatively related to the critical stress calculated from the numerical analysis of void formation.
