“…In the second category, extensive works have been carried out on dealing with the issue of enhancing the properties of core materials. Included in this category is the sandwich panel with irregular arrangement of fibrous core [3], the sandwich panel with Kagome lattice cores reinforced by carbon fibres [16], and also the sandwich panel with a honeycomb core [17][18][19][20][21]. In the third category, a few studies have also been carried out on introducing a new element to improve the properties of composite sandwich panel such as sandwich panel with additional sheets inserted within the core [25], and more recently, insulated concrete sandwich wall panel reinforced with glass fiber reinforced polymer as the shear connector [26].…”

“…The layered configuration of the sandwich panel, the considerable differences in the elastic properties between the face-sheets and the core, and the manufacturing process make the panel susceptible to defects in the form of debonding between the face-sheets and the core [4]. A lot of research work has been done on improving the properties of sandwich panel composites [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. The enhancement efforts were done by either improving the skin or core properties or even introducing a new element inside to form a hybrid sandwich structure.…”

Polymeric composites reinforced with natural fibers have raised more attention as the alternative building materials. In this work, natural fiber composites prepared from jute and hemp fiber were proposed for the intermediate layer of a hybrid sandwich panel. This paper presented the flexural behavior of the newly developed hybrid sandwich panel which included the comparison of the ultimate load, load-deflection behavior, load-strain behavior and failure modes. The study was designed as a single factor experiment where the performance of hybrid sandwich panels containing jute fiber composite (JFC) and hemp fiber composite (HFC) as the intermediate layer was compared to the control (CTR) which was a conventional sandwich panel without an intermediate layer. A static flexural test under a four-point bending load scheme was performed in accordance with the ASTM C 393-00 standard. Aluminium sheet was used as the skins, while expanded polystyrene (EPS) was employed for the core. The testing was performed using a 100 kN servohydraulic machine with a loading rate of 5 mm/min. The applied load, displacement and strains were obtained using data logger. The results demonstrated that the hybrid sandwich panel exhibited a more superior performance than the conventional sandwich panels. The intermediate layer contributed significantly to enhancing the load carrying capacity of the hybrid sandwich panel. The load carrying capacity of hybrid panel with the JFC intermediate layer was 29.60% higher than the conventional sandwich panel, and correspondingly 93.46% higher for the sandwich panel with the HFC intermediate layer.The hybrid sandwich panels also developed a much larger area under the load-deflection curve, indicating greater toughness. The introduction of intermediate layer helped the hybrid sandwich panels to sustain a larger strain prior to reach their ultimate loads, resulting in a higher deformation capability. Indentation and core shear were observed as the failure mode of the conventional sandwich panel. Meanwhile, core shear and delamination were identified as the failure mode of the hybrid sandwich panel.

“…Researchers have also investigated the mechanical properties of sandwich panels using lattice core construction, including in-plane compression, out-of-plane compression, and bending (Fan et al 2007;Fan et al 2006). In these studies, the panels used metal or FRP components, which in general have significantly different failure mechanisms and generally higher performance characteristics than wood-based materials.…”

Mechanical analysis is presented for new high-strength sandwich panels made from wood-based phenolic impregnated laminated paper assembled with an interlocking tri-axial ribbed core. Four different panel configurations were tested, including panels with fiberglass fabric bonded to both outside faces with self-expanding urethane foam used to fill the ribbed core. The mechanical behaviors of the sandwich panels were strength tested via flatwise compression, edgewise compression, and third-point load bending. Panels with fiberglass exhibited significantly increased strength and apparent MOE in edgewise compression and bending, but there were no noticeable effects in flatwise compression. The foam provided improved support that resisted both rib buckling and face buckling for both compression and bending tests. Post-failure observation indicated that core buckling dominated the failures for all configurations used. It is believed that using stiffer foam or optimizing the dimension of the core might further improve the mechanical performance of wood-based sandwich panels.

Fiber reinforced lattice composites are lightweight attractive due to their high specific strength and specific stiffness. In the past 10 years, researchers developed three-dimensional (3D) lattice trusses and two-dimensional (2D) lattice grids by various methods including interlacing, weaving, interlocking, filament winding and molding hotThe project was supported by the press. The lattice composites have been applied in the fields of radar cross-section reduction, explosive absorption and heatresistance. In this paper, topologies of the lattice composites, their manufacturing routes, as well as their mechanical and multifunctional applications, were surveyed.
