Honeycomb Fiber-Reinforced Polymer (HFRP) sandwich panels with sinusoidal core geometry have shown to be successful both for new construction and rehabilitation of existing bridge decks. The development of standards and guidelines is needed in order to promote wider acceptance of composite sandwich products in construction. Much effort has been devoted to the modeling, optimization, and strength evaluation of the HFRP panel at West Virginia University (WVU), in terms of both experimental investigations and analytical solutions. Based on these studies, design guidelines are proposed considering various failure modes. The guidelines are then used to review the design of an existing HFRP sandwich panel, to verify their applicability. Finally, recommendations to improve the strength of HFRP panels are presented.
