Using experimentally obtained specific material properties, a numerical finite element model of a hollow cylindrical structure was designed and experimentally verified. A wall of sandwich composite comprised facesheets from wound glass fibre and polyvinylester resin and a core from recycled paper hexagonal honeycomb impregnated with polyvinylester resin. This model was used to determine the optimal geometrical arrangement of hollow cylindrical structure stiffness elements to supply the stiffness and strength properties with the largest efficiency of fibre reinforced plastic volume usage. It was determined that the cylinder diameter had a significant influence on the arrangement of the stiffness elements only if the diameter has relatively low value.
