Hybrid sandwich panel with natural fibre composite intermediate layer: manufacturing process and significance analysis

Natural fiber reinforced plastic (NFRP) has drawn more attention as an alternative materials, particularly when dealing with the concept of green or sustainable building. Although many efforts have been introduced, most results remain unsatisfied either structurally or economically. In this study, NFRP laminates were incorporated as the intermediate layer of hybrid structural insulated panels (hybrid SIPs). Two types of natural fibers, Jute and Hemp, were used to produce laminates for the intermediate layer. A total of 24 panels samples were tested using 4 point bending load scheme under half and full scale model followed by a statistical analysis of the results. The result shows the potential of using NRFP to improve the structural properties of hybrid SIPs
