This study focuses on estimating the flexural strength, flatwise compressive strength, and edgewise compressive strength of different types of sandwich panels. The first type was a conventional sandwich panel made of two face sheets of galvanized steel with a polyurethane foam core (PSP). The second is a honeycomb sandwich panel made of two aluminum face sheets with a structural core of PVC tubes (HSP1). The third is (HSP1) with polyurethane foam used to fill the cavities of the core cells (HSP2). The fourth is (HSP1) With the addition of partitions of the same cell material to divide each cell cavity into four cavities (HSP3). The mechanical properties of the sandwich panels were studied. The third sandwich panel (HSP3) has higher mechanical properties values compared to other tested sandwich panels but it had the highest density.
