Abstract

Kebutuhan akan struktur kapal yang ringan namun tetap kokoh mendorong penggunaan material alternatif seperti panel sandwich komposit dengan inti berbentuk honeycomb. Penelitian ini bertujuan untuk menganalisis kekuatan ultimate dan efisiensi berat dari panel sandwich yang menggunakan baja A36 sebagai faceplate dan aluminium 5052-H32 sebagai core, untuk diaplikasikan pada struktur geladak kapal kontainer. Variasi yang digunakan mencakup dua ukuran diameter core, yaitu 75 mm dan 150 mm, dengan kombinasi ketebalan faceplate 4 mm dan 5 mm, serta ketebalan core 4 mm hingga 6 mm. Analisis dilakukan secara numerik menggunakan metode elemen hingga (FEM) dengan pembebanan statik akibat tumpukan kontainer 20 feet. Hasil simulasi menunjukkan bahwa seluruh konfigurasi panel sandwich memenuhi batas tegangan izin sebesar 195,83 MPa dan batas deformasi struktural. Konfigurasi optimal ditentukan berdasarkan tegangan dan deformasi terendah serta efisiensi berat terhadap geladak baja konvensional. Diperoleh bahwa konfigurasi dengan diameter core 150 mm, faceplate 5 mm, dan core 6 mm merupakan yang paling ideal, dengan tegangan maksimum 130,15 MPa, deformasi 0,72752 mm, dan pengurangan berat sebesar 15,74%. Dengan demikian, panel sandwich komposit honeycomb terbukti layak dan efisien sebagai alternatif struktur geladak kapal kontainer dalam mendukung efisiensi desain kapal modern.

The demand for lightweight yet structurally strong ship components has encouraged the use of alternative materials such as composite sandwich panels with honeycomb cores. This study aims to analyse the ultimate strength and weight efficiency of sandwich panels using A36 steel as the faceplate and 5052-H32 aluminium as the core, applied to the deck structure of a container ship. Two core diameters were used: 75 mm and 150 mm. These were combined with faceplate thicknesses of 4 mm and 5 mm, and core thicknesses ranging from 4 mm to 6 mm. A numerical analysis was conducted using the Finite Element Method (FEM) under static loading conditions caused by stacked 20-foot containers. The results show that all panel configurations meet the allowable stress limit of 195.83 MPa and satisfy structural deformation criteria. The optimal configuration was determined based on the lowest stress and deformation values, as well as weight efficiency compared to conventional steel plate decks. The configuration with a 150 mm core diameter, 5 mm faceplate, and 6 mm core thickness was found to be the most optimal, yielding a maximum stress of 130.15 MPa, deformation of 0.72752 mm, and a weight reduction of 15.74%. Therefore, honeycomb composite sandwich panels are proven to be structurally viable and efficient as an alternative material for container ship deck structures, supporting improved vessel performance and fuel efficiency.
