The paper presents mechanisms leading to the deformation of the spatial structure of composite foams and phases of foam destruction. Various types of deformation depending on the structure of foam are discussed. The relevant description makes use of recognized elementary models of a cuboidal open and closed cells. The production of foam by blowing a gas into a liquid composite (AlSi9–SiC) allows to control the quantity of energy absorbed during the destruction of foams subject to free one-axis compression.
