Abstract

Kapal Laut di wilayah Indonesia banyak menggunakan material Fiberglass Reinforced Plastics (FRP) sebagai bahan konstruksinya tentu pada bagian lambungnya dikarenakan memiliki beberapa keunggulan seperti konstruksi ringan, biaya produksi murah, proses produksi cepat dan teknologi sederhana. Tetapi dengan menggunakan material Fiberglass Reinforced Plastics (FRP) mempunyai kelemahan yaitu stabilitas mekanik kurang baik dari pada kapal dengan material lain, kapal mudah terbawa oleh angin, tenaga pada kapal ikan untuk menarik peralatan penangkapan terlihat lebih lemah. Pada penelitian ini peniliti ingin menggunakan material Fibercarbon Reinforced Plastics sebagai material untuk lambung kapal karena material fiber carbon memiliki kelebihan dibanding fiber glass seperti kekuatan dan kekakuan tinggi. Penambahan MAH (anhidrat maleat) berfungsi sebagai coupling agent yang bertujuan untuk meningkatkan daya adhesi antara matrik dengan interface sehingga komposisi komposit semakin kuat. Penelitian ini bertujuan untuk menganalisa sifat mekanik dan morfologi komposit serat karbon/epoksi untuk lambung kapal dengan variasi penambahan coupling agent MAH. Pengujian yang dilakukan pada penelitian ini antara lain Scanning Electron Microscope (SEM), Fourier Transfromation Infrared Spectroscopy (FTIR), uji tarik, uji kekerasan dan uji densitas. Hasil dari Pengujian FTIR terdapat gugus fungsi O-H pada daerah serapan 3482.35 cm-1 , gugus fungsi C-H aromatic pada daerah serapan 3034.30 cm-1 , C=C pada daerah serapan 1609.09 cm-1 dan terdapat C-O-R ether pada daerah serapan 1027.14 cm-1 yang menunjukkan material ini merupakan epoksi. Kemudian dengan penambahan coupling agent MAH terdapat gugus fungsi C=O sekitar 1700 cm-1. Secara Morfologi dapat dilihat penambahan MAH pada komposit, meningkatkan interface yang terbentuk antara serat dan matriks dengan menggunakan gambar SEM, diperoleh nilai rata-rata ukuran serat karbon sebesar 5,941 ± 4,862 m. Pada Pengujian Tarik didapat bahwa kekuatan tarik meningkat. Kekuatan Maksimum didapat pada penambahan 4% MAH yaitu sebesar 256.96 MPa dan Nilai Elongasi maksimum didapat pada penambahan 8% MAH yaitu sebesar 26,73 %. Pada Pengujian Kekerasan didapat bahwa kekerasan meningkat dan hasil maksimum pada penambahan 4% MAH yaitu sebesar 67,33 HD. ============================================================================================================ Marine vessels in the region of Indonesia mostly use Fiberglass Reinforced Plastics (FRP) materials as construction materials on hull because it has several advantages such as light construction, low cost production, fast production process and simple technology. But using Fiberglass Reinforced Plastics (FRP) materials has a disadvantage such as mechanical stability is less good than the ship with other materials, the ship is easily carried by the wind, power on the fishing boat to attract the fishing equipment looks weaker. In this study researchers wanted to use Fibercarbon Reinforced Plastics material as a material for ship hull because carbon fiber material has advantages over glass fibers such as higher strength and stiffness. Then Addition MAH (maleic anhydride) has a function as a coupling agent that aims to improve the adhesion between the matrix with the interface so make the composite stronger. This study aims to analyze the mechanical and morphological properties of carbon fiber/epoxy composites for ship hull with variations the addition of MAH coupling agent. Tests conducted in this study include Scanning Electron Microscope (SEM), Fourier Transfromation Infrared Spectroscopy (FTIR), tensile test,hardness test and density test. The results of the FTIR Test contained an OH functional group in an absorption area of 3482.35 cm-1, a functional group of CH aromatic in an absorption area of 3034.30 cm-1, C = C in an absorption area of 1609.09 cm-1 and there was COR ether in an absorption area of 1027.14 cm-1 shows this material is epoxy. Then with the addition of MAH coupling agent there is a functional group C = O about 1700 cm-1. Morphology can be seen the addition of MAH on the composite, improving the interface formed between fiber and matrix and by using SEM image, average carbon fiber diameter size is 5.941 ± 4.862 m. In Tensile Test it is found that tensile strength increases. Maximum strength obtained in the addition of 4% MAH is 256.96 MPa and Maximum Elongation Value obtained at 8% MAH addition is 26.73%. In Hardness Testing it is found that the hardness increases and the maximum value on the addition of 4% MAH is 67.33 HD.
