Abstract
Industri kereta api juga termasuk perusahaan yang mengembangkan aplikasi komposit pada gerbong kereta api. Aspek keselamatan dan kenyamanan adalah hal utama yang menjadi perhatian Industri kereta api dalam produksi transportasi masal tersebut. Dalam proses produksinya digunakan proses pembuatan komposit untuk perakitan seperti panel interior, front and end mask, kursi penumpang dan rak kabin muatan. Pada proyek kereta dilakukan proses produksi komposit, maka dilakukan proses spesifikasi fire retardant dengan standar ORE B 106.2 metode 1A kelas B untuk meminimalisir kebakaran pada card/gerbong kereta.Standar sifat mekanik dari Industri Kereta Api yaitu kekuatan tarik sebesar minimal 75 N/mm2, kekuatan bending minimal 140 N/mm2, kekuatan impak minimal 4,5 J/cm2 dan kekerasan minimal 40 barcol. Penelitian ini menggunakan komposit GFRP dengan bahan berupa Serat Kaca E-Glass Chopped Strand Mat, Woven Roving, Matriks Poliester Yucalac 157 BQTN-EX, MEKP, dan Cobalt-N. Variasi dilakukan dengan penambahan 0, 2 , 4, 6 dan 8%wt Aluminium Hidroksida sebagai bahan penahan api. Komposit dibuat dengan metode hand lay up pada cetakan. Pengujian yang dilakukan pada penelitian ini antara lain Scanning Electron Microscope (SEM), Fourier Transfromation Infrared Spectroscopy (FTIR), Uji tarik, Uji kekerasan,Uji impak, Uji bending dan Uji Fire Retardant. Hasil dari Pengujian FTIR terjadi penurunan intensitas absorban karena penambahan Aluminium Hidroksida. Secara morfologi dapat dilihat penambahan Aluminium Hidroksida pada komposit memperluas daerah interface, mengurangi void dan atom atom pada serat dan matriks lebih rapat. Secara mekanik mengalami penurunan kekuatan tarik, kekuatan bending dan burning rate. Mengalami peningkatan kekuatan impak dan kekerasan. Kekuatan Tarik dan kekuatan bending Komposit GFRP memiliki nilai maksimal pada penambahan 0% dengan nilai kekuatan 145.53 MPa dan 212.735 MPa. Burning Rate, kekuatan impak dan kekerasan memiliki nilai maksimal pada penambahan 8% dengan nilai 68.25 cm2/min, 8.37 mm/menit, 19.911 J/cm2 dan 78 Barcol.

The railroad industry also includes companies that develop composite applications on railroad cars. Aspects of safety and comfort are the main things that concern the railroad industry in mass transportation production. In the production process a composite manufacturing process is used for assembly such as interior panels, front and end masks, passenger seats and cargo cabin racks. In the train project a composite production process is carried out, the fire retardant specification process is carried out with the ORE B 106.2 standard method B class 1A to minimize fire on the train card / carriage. Standard mechanical properties of the Railway Industry are tensile strength of at least 75 N / mm2 minimum bending of 140 N / mm2, minimum impact strength of 4.5 J / cm2 and minimum hardness of 40 barcol. This study uses GFRP composites with materials such as E-Glass Chopped Strand Mat, Woven Roving, BQTN-EX Yucalac Polyester Matrix, MEKP, and Cobalt-N. Variations were carried out with the addition of 0, 2, 4, 6 and 8% wt of Aluminum Hydroxide as a fire retardant. Composites are made using the hand lay up method on the mold. Tests conducted in this study include Scanning Electron Microscope (SEM), Fourier Transfromation Infrared Spectroscopy (FTIR), Tensile Test, Hardness Test, Impact Test, Bending Test and Fire Retardant Test. The results of FTIR testing decreased the intensity of absorptions due to the addition of Aluminum Hydroxide. Morphologically, it can be seen that the addition of Aluminum Hydroxide to the composite extends the interface area, reducing the void and atomic atoms in the fiber and matrix more tightly. Mechanically decreases tensile strength, bending strength and burning rate. Experiencing increased impact strength and hardness. Tensile Strength and Bending Strength GFRP composites have a maximum value of 0% with a value of 145.53 MPa and 212,735 MPa. Burning Rate, impact strength and hardness have a maximum value at the addition of 8% with a value of 68.25 cm2 / min, 8.37 mm / minute, 19,911 J / cm2 and 78 Barcol.
