Abstract
Aim. The article is devoted to theoretical studies given characteristics of the discrete aggregate with octagonal, diamond-shaped, round or square shape of the cell.
Methods. At the present time it was determined that in many sandwich constructions the discrete honeycomb are begun to apply. The geometric shape of the cross-sections of discrete aggregates is very varied. However, studies related to the definition of the above characteristics of discrete aggregates, to select the optimal form, is not enough.
Results. It was found that the mechanical characteristics of the discrete filler filling factor are depended on the cell.
Conclusion. It was proved that the ultimate tensile compression fillers along Z axis at the same height perimeter secheniyai depends mainly on the ratio of the fill factor and cell sizes, with the highest crush strength has a diamond-shaped cell.
