“…Karlsson and Astrom (1997) suggested that reinforcing through thickness with fibers can 274 potentially significantly improve the structural integrity of sandwich composites. Thus, Reis 275 and Rizkalla (2008) developed a 3-D fiber reinforced composite sandwich panel (Fig. 4) which 276 increased the shear modulus and through-the-thickness compressive strength of the foam core 277 but caused a decrease in the tensile strength and stiffness of the skin due to the waviness created 278 by the stitched fibers.…”

3Fiber reinforced polymer (FRP) sandwich systems as primary load-bearing elements are 4 relatively new concepts in lightweight civil infrastructure. These systems offer a combination 5 of light weight, high strength, thermal insulation for some types, and service-life benefits. 6Recent developments and applications have demonstrated that these composite systems have 7 emerged as a cost-effective alternative, especially when each material component is 8 appropriately designed. Still, some issues and challenges need to be addressed if FRP systems 9 are to gain widespread use in civil infrastructure. This paper provides an overview of the state-10 of-the-art research, development, and applications of FRP sandwich systems. It also identifies 11 the challenges and future opportunities for the broad use of these advanced systems in civil 12 engineering and construction. 13

“…A detailed understanding of the behaviour and failure mechanisms of individual composite sandwich beams in the two different positions is therefore necessary to design a structure made from this composite material. 4 A number of researches have studied the behaviour and failure modes of sandwich structures in flexure [2,11,12,[17][18][19]. In these studies, sandwich specimens are tested in the flatwise position as it is commonly used as structural panels for roof, floor, walls and bridge decks.…”

The flexural behaviour of a new generation composite sandwich beams made up of glass fibre reinforced polymer skins and modified phenolic core material was investigated. The composite sandwich beams were subjected to 4-point static bending test to determine their strength and failure mechanisms in the flatwise and the edgewise positions. The results of the experimental investigation showed that the composite sandwich beams tested in the edgewise position failed at a higher load with less deflection compared to specimens tested in the flatwise position. Under flexural loading, the composite sandwich beams in the edgewise position failed due to progressive failure of the skin while failure in the flatwise position is in a brittle manner due to either shear failure of the core or compressive failure of the skin followed by debonding between the skin and the core. The results of the analytical predictions and numerical simulations are in good agreement with the experimental results.

“…Fam et al (2010) explored the feasibility of fabrication and flexural performance of panels composed of low-density polyurethane foam core sandwiched between two GFRP skins. Reis and Rizkalla (2008) presented an innovative 3-D glass fibre reinforced polymer (GFRP) panels with foam-core designed to overcome delamination problems, typically encountered in traditional sandwich panels. Sharafi et al (2010) studied the flexural behaviour of sandwich panels fabricated by laminating two glass fibre reinforced polymer skins to a prefabricated polyurethane foam core.…”

In this paper, an innovative and efficient sandwich panel is proposed for the structural walls for quickly assembled post-disaster housing, as well as load bearing panels for pre-fabricated modular construction and semi-permanent buildings. This study focuses on the flexural and shear behavior of the innovative sandwich panels, which is composed of two 3-D high density polyethylene (HDPE) skins, and high-density Polyurethane (PU) foam core. An experimental study was carried out to validate the effectiveness of this panel for increasing the ultimate bending strength. A series of experimental tests were performed on medium-scale specimens to characterize their core shear behavior. Then, some supplementary tests were run to determine the panels' flexural and shear stiffness. The numerical and experimental investigations show that the 3-D-HDPE sheets, manufactured with a studded surface; considerably enhance the pull-out and delamination strength. Good agreement has been observed between the numerical and experimental tests.
