Abstract
The use of polymer composite materials for highly loaded structures in modern engineering is constantly expanding, since they have high specific strength characteristics under static loading. However, the question of providing the required resource of such materials under cyclic loading remains open. In this work, we propose an experimental technique for assessing the damageability of specimens of layered polymeric material during fatigue tests. Criteria, which can indicate the appearance of interlayer fracture in the tested specimens, are given. A correlation between the appearance of a new spot of interlayer destruction in the specimens and a decrease in a number of acoustic emission events per unit time, during fatigue tests, were revealed.
