“…Rigid PU foam is one of the most efficient, high-performance insulation materials, enabling very effective energy savings with minimal occupation of space. A 100 mm thick layer of rigid PU provides a U-value of 0.04, which demonstrates high insulation performance of PU foam [21]. U-values measure how effective a material is an insulator.…”

Abstract:In this paper, the development process of a deployable modular sandwich panelized system for rapid-assembly building construction is presented, and its structural performance under some different action effects is investigated. This system, which includes an innovative sandwich panel and its integrated connections, can be used as structural walls and floors in quickly-assembled postdisaster housing, as well as load-bearing panels for prefabricated modular construction and semipermanent buildings. Panels and connections are composed of a pneumatic fabric formwork, and two 3D high-density polyethylene (HDPE) sheets as the skins, filled with high-density rigid polyurethane (PU) foam as the core. HDPE sheets manufactured with a studded surface considerably enhance stress distribution, buckling performance, and delamination strength of the sandwich panel under various loading conditions. The load-carrying behavior of the system in accordance with some American Society for Testing and Materials (ASTM) standards is presented here. The results show the system satisfies the codes' criteria regarding semipermanent housing.

“…The popular type of PU foam, being used for thermal insulation, refrigeration and water heater system is made of a 100:100-110 weight ratio mixture of AUSTHANE POLYOL AUW763 and AUSTHANE MDI [18]. This foam is formulated using a zero Ozone Depletion Potential (ODP), zero Global Warming Potential (GWP) and Volatile Organic Compound (VOC) exempt blowing agents.…”

“…1. The HDPE sheets manufactured with approximately 1200 studs per square meter, provide higher pull-out and delamination strength, as well as better stress distribution, and buckling performance (Sharafi et al, 2018b,c;Nemati et al, 2018). The studs also improve the resistance of the face sheets and foam-core from debonding and increasing the interface strength between the foam-core and the face sheets.…”

“…Kujawa and Szymczak (2014) investigated rotational resistant stiffness of the zed-purlins connection with sandwich panels. A new foam-filled sandwich panel was developed by Sharafi and coworkers (Sharafi et al, 2018b,c ;Nemati et al, 2018), which is composed of 3-D high density Polyethylene (HDPE) sheets, as the skins with a thickness as 2 mm, and high-density PU foam core with a total thickness as 100 mm. This paper investigates the performance of the integrated connections for the newly developed composite panel, and experimentally and numerically assesses their structural performance under monotonic loading.…”

Connections represent major challenges in the design of composite structures, mainly because they entail discontinuities in the geometry of the structure and material properties, and introduce high local stress concentrations. Despite some constructability complications, integrated connection could be a reliable solution. In this paper, the structural behaviour of an integrated connection for implementation between adjacent composite sandwich panels in rapid assembly buildings is studied. The integrated connection system consists of 3-D high density polyethylene (HDPE) skin faces, and cores of high-density polyurethane (PUR) foam integrated into the sandwich panels at the moment of their production. The study included experimental investigations regarding the mechanical and structural response of the connection under actual applied loads, and its torsional rigidity, rotational stiffness and behaviour under lateral loading is investigated. Using Finite Element modelling, the stress distribution and the mechanisms of failure are studied. The results show a good agreement between the numerical and experimental results.
