“…The theoretical concept of this new hybrid sandwich panel was comprehensively developed by Fajrin (2015). Further, Fajrin et al (2016Fajrin et al ( , 2017 experimentally investigated the suitability of the hybrid sandwich panels for structural applications and found that they can be applied for the structure under flexural or in-plane shear loading. Essentially, there are two main criteria in the selection of core materials used in sandwich panel structure; the design criteria and the specific application (Davies, 2008), hence all lightweight materials may be used for the core.…”

Among the many choices of composite sandwich panel cores, Balsa wood is one of the main alternatives of cores made of wood. However, the availability and price of Balsa wood are quite expensive, so it needs alternatives from other types of wood such as Sengon wood. The purpose of this study was to evaluate the feasibility of Sengon wood as a core of composite sandwich panels. Three variations of the Sengon wood layout had been prepared as the core of the sandwich panels with a skin made of aluminum. All specimens, including the control specimens made of whole Sengon wood, were prepared with a size of 550 x 50 x 24 mm for length, width, and depth, respectively. Each variation and also the control specimens were made of 3 pieces. Tests were carried out based on the ASTM C 393-94 standard under the three-point bending test scheme. The results showed that the sandwich panel with plain Sengon wood core has the highest capacity to carry a flexural load, which is approximately 177.391 MPa, followed by a sandwich panel with long and end grain Sengon board that possess flexural strength of 153.913 MPa and 79.101 MPa, respectively. The flexural strength of these sandwich panels is superior to solid Sengon wood. The sandwich panels showed a typical ductile material indicated by a non-linear curve without a distinct yielded point before reach the maximum failure load. Three sandwich panels with various Sengon wood cores collapsed under three types of failure mechanisms; face wrinkling, shearing of the core, and delamination between the interface of skin and core. In conclusion, Sengon wood has a great potential to be used as the core material for a composite sandwich panel.

“…Initially, this emerging material was extensively investigated in relation to mechanical engineering applications, but it now has extended to other engineering fields such as in civil engineering. Many studies have also been focused on developing building components, among these was the hybrid structures for structural applications as reported by Fajrin [3] and Fajrin et al [4][5][6].…”

This paper discusses the results of an experimental investigation on the shear properties of natural fibre composites using the V-Notch or Iosipescu shear test. The natural fiber composites were made of jute and hemp fibers reinforced epoxy polymer resin. The testing was conducted using an MTS machine equipped with a 10 kN load cell in accordance with the ASTM standard D5379M. The testing machine was set-up to apply a load with a speed of 2 mm/min. It was found that the jute fiber composites (JFC) have an average shear stress of 25.56 MPa, while the hemp fiber composites (HFC) have an average value of 22.46 MPa. The loaddisplacement graphs showed a nearly linear trend at the initial loading stage that slightly deflected prior to reaching the maximum load. Most of the specimens in both groups, JFC and HFC, showed fractures in a diagonal cracking pattern, known as an off-axial failure mode. Only a few specimens collapsed across the notched section. Both are customary failure modes for this type of shear test.

“…Another study was carried out by Do et al (2013) on the ultimate limit state assessment of stiffened panel structures for extremely large ore carriers. The alternative hybrid structural panel was elaborated on by Fajrin et al (2017) in terms of its structural behavior under a pure bending load. Finally, an analytical model is developed by Benbouras et al (2017) under three-point bending for symmetric laminated beams.…”

The midship section in oil tankers has become a major concern for the maximum bending moment during operational conditions. The section is assembled by a top deck structure, side structure, and bottom structure, which is usually supported by a stiffened panel, that is, a panel with an attached stiffener. This study elaborated on the conventional tee stiffener profile on the midship section of an oil tanker structure. Ultimate strength analysis was carried out using the finite element method for all the stiffeners with various geometrical dimensions according to the International Association of Classification Societies. This included the calculation of the section's modulus and mass as related variables, using an analytical approach. The results showed that the ultimate strength, section modulus, and mass were influenced by the alteration of web length and plate thickness. For example, an increase of 10 mm in web length gave an additional value of 2.22% for the ultimate strength, 2.8% for the section modulus, and 0.61% for the mass. In contrast, 1 mm of additional plate thickness increased the ultimate strength by 48.57%, section modulus by 6.91%, and mass by 3.68%.
