Abstract
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.
Highlights
Providing accommodation on a large scale at relatively affordable price has always been a challenging task for government and for housing industry
A response surface methodology (RSM), which is a statistical design of experiment method, was employed by [7] to analyze the factors influencing deflection in sandwich panels subjected to low-velocity impact
Since all the confidence intervals included only positive numbers, it can be concluded that all the treatment means differ. This suggests that the load carrying capacity of hybrid sandwich panels with jute fiber composite (JFC) and hemp fiber composite (HFC) intermediate layer is significantly different with the conventional sandwich panels (CTR)
Summary
Providing accommodation on a large scale at relatively affordable price has always been a challenging task for government and for housing industry. The first factor is to reduce the weight of the structure to maintain affordable prices. The reduction of self-weight of structure by adopting appropriate material results in the reduction of element cross section, size of foundation and supporting elements thereby reduce the overall cost of the housing construction. A panelized housing system is a form of construction in which all housing components are pre-fabricated at factory and shipped to the site for erection. In order to meet these challenges, a research project has been carried out aimed at developing a new type of hybrid composite sandwich wall panel which can be manufactured as modular panelised system. The typical sandwich panel used in building application commonly consists of metal skins and soft core. This paper focuses on the significance analysis of the experimental results on the flexural behaviour of the sandwich panels developed by the authors
