Composite panels with a corrugated core are increasingly being used in numerous engineering applications due to their high strength-to-weight ratio, low material consumption and consequently, lower cost. In this thesis, we designed panels with triangular, trapezoidal, and sinusoidal core shapes, all made from higher density paper. For each sample of the sandwich panel, we varied the amplitude and wavelength of the core. We designed a three-point bending setup for the use in a universal mechanical testing machine for an experimental characterization of the bending stiffness. We have found that sandwich panels with triangular and trapezoidal core shapes have the highest bending stiffness among the fabricated ones and explored different deformation modes for each core shape.
