Efek Sinergis Alumina Trihydrate Dan Melamine Cyanurate Terhadap Ketahanan Api Glass Fiber Reinforced Polymer (GFRP)

Abstract

Glass Fiber Reinforced Polymer (GFRP) in train interior components must have good fire resistance properties. Therefore, it is necessary to add a flame retardant compound to the GFRP material. In this study, Alumina Trihydrate (ATH) and Melamine Cyanurate (MCA) were mixed into a vinyl ester resin. The method of making GFRP refractory specimens uses the hand lay-up method. GFRP is mixed and tested for fire resistance standard ORE B 106.2. The results obtained after the addition of 25% ATH, a mixture of 25% ATH with 5% MCA, 10% MCA with 25% ATH, and 15% MCA with 25% ATH, 25% ATH in the outer layer, and a mixture of 5% MCA with 25% ATH in the outer layer of the resin weight is able to increase fire resistance. Optimum GFRP fire resistance at the addition of 25% ATH to the weight of the resin in the outer layer. The result of the burned area is 84.84 cm² with a fire extinguishing time of 0.33 seconds after the fire source leaves the specimen. The results show that the mixture of ATH and MCA has a synergistic effect on fire resistance properties, so it becomes a recommendation for interior sidewall panels and ceiling panels on trains according to the ORE B 106.2 standard
