“…(Witkiewicz & Zielinski, 2006) melaporkan hasil investigasi pembuatan polyurethane foam yang menunjukkan bahwa polyurethane foam memiliki nilai kekuatan tarik lebih rendah dari standard jika difungsikan sebagai core material sandwich panel. (Utomo et al, 2016) melakukan pembuktian akan hal tersebut, dengan menguji material polyurethane foam dari beberapa konsentrasi yang menghasilkan rata-rata kekuatan tarik material hanya sebesar 0,22 Mpa jauh dibawah standard yang diberikan oleh DNV yaitu 16,1 Mpa pada temperatur ruang. Berdasarkan hal tersebut, dilakukan perubahan jenis core material yang digunakan dari polyurethane foam menjadi synthetic resin.…”

“…Berdasarkan hal tersebut, dilakukan perubahan jenis core material yang digunakan dari polyurethane foam menjadi synthetic resin. Sandwich panel sebagai material komposit yang terdiri dari dua jenis material yang berbeda, yaitu pelat baja sebagai faceplate dan synthetic resin sebagai core material (Utomo et al, 2016), memerlukan metode khusus dalam pembuatannya. Seperti SPS (Sandwich Plate System) yang memiliki cara dan langkah pembuatan khusus.…”

Sandwich panel as a composite materials require special method of manufacture, to produce the best of physical condition. This study give the manufacturing process of sandwich panel for the purpose of testing the strength of material. Sandwich panel created with molding method for simplify the process of work and can be repeated if a failure occurs. Saveral failures occur in creating process until preparation specimen process that are influenced by saveral things, such as damage caused by the temperature of the sun, difference in viscosity between the layers of the conditions faceplate (smooth and rough), and the method of cutting the sandwich panel which requires cutting methods at low temperatures and does not produce the high vibration to avoid damage to the material before material strength test were performed.

“…The authors' research group have studied the sandwich material made of steel as the face and resin as the core shown that the core material has a brittle behavior. To decrease the brittleness index of the core, additional filler material is used [10] [11]. Abdullah studied the use of clamshell powder filler for the core material with 10% -50% of the total weight used in the mixture [12].…”

Sandwich material can be used as the substitute for the ship conventional material. The core sandwich material used in this study consisted of a talk-resin-catalyst. The core mixture proportion is 90% resin and 10% talk. A thick steel plates is used as the face of the core sandwich material. Both experimental and numerical simulations are carried out to investigate the bending or flexural behavior of the proposed sandwich material. Three-point bending test has been carried out to determine the yield stress and maximum stress as well as the damage mechanism of the specimen up-to failure. From the investigation, the first failure process occurred at the mid-span as flexural cracks. As the load continue, these flexural cracks progressed until fully fracture of the core material take places. From the experimental investigation, it was found that the yield stress and maximum stress of the sandwich panel are 22.88 MPa and 28.63 MPa. On the other hand, numerical simulation is carried out using ABAQUS which has shown to be sufficient to predict the response of the sandwich-panel. However, a more sophisticated constitutive model is required to successfully model the experimental behavior in close agreement.

Development of sandwich materials for ship structure is aimed mainly to reduce the ship light weight so that the ship payload increases. This paper addresses development of sandwich core material suitable for ship structure. The core materials were composed of synthetic resin and talc; percentages of talc by total weight investigated were 10%, 20%, 30%, and 40%. Laboratory tests stipulated by the Lloyd's Register (LR) and Det Norske Veritas (DNV) were performed on the core materials. Moreover, sandwich plates consisted of steel faceplates and the core materials were tested using ASTM standards including tension, shear, and flexure tests. The sandwich plates were applied for designing car deck of a ro-ro ship. Analysis of the sandwich deck under design load utilizing finite element approach was carried out to select the best sandwich core materials developed in this study. It was observed that the sandwich panel deck composed of synthetic resin and core material with 40% talc was better than the others.
