Abstract

Perkembangan material kini telah mengalami kemajuan cukup pesat yang ditunjukkan dengan adanya beberapa material inovatif yang dikembangkan dan digunakan pada berbagai macam bentuk konstruksi, termasuk untuk material konstruksi kapal. Material sandwich panel yang merupakan material komposit, dalam bentuk lapisan antara dua jenis material yang berbeda kini telah berkembang penggunaanya dalam industri perkapalan, seperti sandwich plate system dengan kombinasi pelat baja dan polyurethane elastomer. Penelitian ini melakukan analisa material komposit sandwich panel dengan kombinasi pelat baja dan beberapa core material yang mudah ditemukan dalam industri perkapalan dalam negeri, yaitu polyurethane foam, polyresin dan synthetic resin. Identifikasi dilakukan dengan metode eksperimen yang meliputi pengujian reaktivitas, densitas dan kekuatan tarik material untuk mendapatkan nilai persyaratan yang diberikan oleh DNV. Investigasi juga dilakukan pada material sandwich panel yang berhasil dibuat dengan kombinasi pelat baja sebagai lapisan faceplate dan synthetic resin (50% resin : 50% talk : 0,3% katalis) sebagai core material, untuk mendapatkan nilai kekuatan material sampai pada pegaruh aplikasi material dibagian struktur pelat datar pada konstruksi kapal. Berdasarkan hasil penelitian, sandwich panel memberikan peningkatan nilai kekuatan core material 79,07% dan menambah nilai regangan core material 75,27% dengan kemampuan absorpsi beban sebesar 29,02% dari kondisi baja normal. Analisa aplikasi sandwich panel pada struktur kapal menunjukkan perubahan bentuk konstruksi dengan berkurangnya penggunaan penegar dan penumpu, sehingga menghasilkan perubahan berat konstruksi sebesar -13,08%. Analisa tersebut hanya dilakukan pada beberapa block di bagian parallel middle body kapal, sehingga kedepannya perlu dikembangkan pada bentuk full body kapal ========================================================================================================= The development of materials has now been rapid progress with some innovative materials that are developed and used in various forms of construction, including for ship construction material. Sandwich panel material is a composite material, in the form of a layer between two types of different material that has now developed its use in the shipping industry, such as sandwich plate system with a combination of steel plates and polyurethane elastomers. This research will analyze the composite sandwich panel material with a combination of steel plate and some core materials which are easily found in the national ship industry, such as polyurethane foam, polyresin and synthetic resin. Identification is conducted with experimental method, which includes the reactivity test, density test and strength of the material, to obtain the required values given by DNV. Investigation are also conducted at sandwich panel material were successfully created, with a combination of steel plates as a layer faceplate and synthetic resin (50% resin : 50% talc : 0,3% catalyst) as the core material, to get the value of strength material and applications effects in structural flat plate in the ship construction. Based on the experiment results, sandwich panel provide improved strength of core material 79,07% and increases the strain value of core material until 75,27%, with load absorption capability until 29,02% compared to normal steel material. The analysis of sandwich panel application in the ship structure has shown the changes in the form of construction, by the reduction of longitudinal girders and stiffeners. The reduction of girders and stiffeners reduces the weight of construction to -13,08%. The analysis is only done at several blocks in the parallel middle body of the ship, for the next research needs to be developed in the full body of the ship.
