“…The typical sandwich panel used in building application commonly consists of metal skins and soft core. Although oriented strand board (OSB) is commonly employed for the skin of sandwich structure in structural insulated panels (SIPs), the observed shortcomings of this typical skin such as mould build-up and disintegration in the presence of flood water [1] have reduced their usage. In this study, metal based skins such as aluminium or steel are adopted.…”

This paper presents the significance analysis of a new type of hybrid composite sandwich wall panel which can be manufactured as modular panelised system. Two different types of natural fibers reinforced plastics (NFRP) laminate were incorporated into the new sandwich panel as an intermediate layer. The significance analysis in this research has been carried out using analysis of variance (ANOVA). As the aim of the analysis is to select the most appropriate natural fiber composites for the intermediate layer, the experiments were arranged as a single factor experiment in which 3 levels of a factor have been examined. The factor refers to the type of intermediate layer used in the sandwich panel.The result of this study shows that the incorporation of intermediate layer has significantly enhanced the load carrying capacity of the sandwich panels.

“…The greatest advantage of SIPs is that they allow structural support and insulation to be incorporated into a single system, which enables greater durability (Kermany, 2006). OSB is commonly used for the skin of SIPs, but the possibility of mold build-up and disintegration in water limits OSB's use as a skin (Vaidya et al, 2010). Kawasaki et al (1999) developed a wood-based sandwich panel with a low-density fiberboard core with different face materials for structural insulated walls and floors, and the results showed that low-density fiberboard's heat retention properties were superior to current commercial insulators, such as plastic foams and mineral wools.…”

In addition, Vaidya et al (2010) developed an innovative composite structural insulated panel (CSIP) using E-glass fibers blended with a polypropylene matrix for the skins and an EPS foam core, which was designed for the exterior walls of a modularized structure.

This paper presents the structural behavior of newly-developed hybrid structural insulated panels (SIPs) formed by incorporating lignocellulosic composites-jute fiber composite (JFC) and medium-density fiber (MDF)-as intermediate layers between aluminum skin and an expanded polystyrene (EPS) core. The investigation was conducted as an experimental work. A four-point bending load was performed to create pure bending conditions, and the samples were prepared in accordance with ASTM C 393-00 standards. Testing was performed using a 100 kN servo-hydraulic machine with a loading rate of 5 mm/min. The results show that the incorporation of intermediate JFC or MDF layers enhanced the flexural behavior of the SIPs. The ultimate loads of hybrid SIPs with JFCs or MDF were, respectively, approximately 62.59% and 168.58% higher than the ultimate load achieved by SIPs without intermediate layers.Hybrid SIPs exhibited a much larger area under the load-deflection curve than those of conventional SIPs; this points to the toughness of the material and its ability to sustain larger compression strain prior to reaching their ultimate loads, which prevents them from prematurely failing under buckling or indentation.

Abstract. The advantages of glass fiber reinforced composites (FRP) and SIPs (structural insulated panels) are combined, and a new type of sandwich panel called composite structural insulated panels (CSIPs) is proposed. Through the adhesive bonding, CSIPs are made of FRP as face sheets and expanded polyethylene foam (EPS) as a core. To master the mechanical characteristics of CSIPs, firstly, adopting the large deflection theory of Reissener in this paper derived the calculation formula of displacement and the stability critical load of CSIPs. Then, ANSYS software was used to carry on the analysis of finite element simulation. Finally, a testing piece of CSIP with length 1000mm and breath 1000mm was made and a test was done. The results show that the theoretical analysis results, finite element simulation results and test results are basically coincide. So the calculating formula of deformation and bearing capacity of CSIPs are correct. And CSIPs have the outstanding advantages of light weight and high strength.
