The primary objective of this research program is to study and examine the structural performance of innovative 3-D FRP sandwich panels produced by Martin Marietta Composites, USA. The panels consist of GFRP laminates and foam core sandwich where top and bottom skin GFRP layers are connected together with through-thickness fibers. Failure modes and mechanisms are investigated through a comprehensive experimental program at NC State University. Stiffness and strength analysis methodologies are established and a complete set of design guidelines for FRP Sandwich panels are provided. This research is currently in progress at the Constructed Facilities Laboratory at North Carolina State University, NC, USA.
