Abstract
Material komposit Glass Fiber Reinforced Polymer (GFRP) dikembangkan dalam interior kereta api pada panel interior, front and end mask, kursi penumpang dan rak kabin muatan. Pada perkembangannya, dibutuhkan sifat tahan api untuk memenuhi kebutuhan industri. Penelitian ini bertujuan mengamati penambahan filler Magnesium Hidroksida (Mg(OH)2) sebagai bahan penahan api pada komposit. 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 Magnesium Hidroksida. Komposit dibuat dengan metode hand lay up pada cetakan. Hasil dari Pengujian FTIR terjadi penurunan intensitas absorban karena penambahan Magnesium Hidroksida. Pengujian morfologi menunjukkan penambahan Magnesium Hidroksida memperburuk antarmuka. Pengujian mekanik menujukkan penambahan Magnesium Hidroksida menaikkan kekerasan, kekuatan impak dan ketahanan api serta menurunkan kekuatan tarik, kekuatan lentur, dan modulus elastisitas komposit GFRP. Material tahan api yang memenuhi spesifikasi teknik interior kereta api adalah 2%wt Mg(OH)2 dengan kekuatan tarik 84.95 N/mm2, kekuatan lentur 160.86 N/mm2, modulus lentur 7225.74 N/mm2, kekerasan 67 Barcol dan kekuatan impak 10.19 J/cm2.

Glass Fiber Reinforced Polymer (GFRP) composite materials are developed in train interiors on interior panels, front and end masks, passenger seats and cargo cabin racks. In its development, fire retardant properties are needed to meet industrial needs. This study aims to observe the addition of Magnesium Hydroxide (Mg (OH)2) filler as a fire retardant in the composite. 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 are carried out with the addition of 0, 2, 4, 6 and 8% wt of Magnesium Hydroxide. Composites are made using the hand lay up method on the mold. The results of FTIR testing shows a decrease on the absorbance intensity due to the addition of Magnesium Hydroxide. Morphological testing shows the addition of Magnesium Hydroxide to worsen the interface. Mechanical testing shows the addition of Magnesium Hydroxide to increase hardness, impact strength and fire resistance and reduce tensile strength, flexural strength, and modulus of elasticity of GFRP composites. Fireproof material that meets the railway interior engineering specifications is 2% wt Mg (OH)2 with tensile strength 84.95 N/mm2, flexural strength 160.86 N / mm2, flexural modulus 7225.74 N/mm2, hardness 67 Barcol and impact strength 10.19 J/cm2.
