The current paper briefly summarizes numerical and experimental results obtained investigating sandwich panels with plywood face sheets and corrugated plywood or glass fibre reinforced plastics (GFRP) core. Developed numerical models have been validated against 4-point bending tests where good correlation between experimental and numerical results in the region of elastic mechanical behaviour has been found. Employing validated numerical model optimum design employing metamodelling methodology has been per-formed on cross-section parameters to find trade-off between panel stiffness and mass compared to traditional plywood boards. It has been found that panels with GFRP core can be optimised to achieve higher stiff-ness/mass ratio in contrary to panels with plywood corrugated core.
