Improvement of Fire Resistance on GFRP Composites by Addition of Pumice Particle
摘要
Glass Fiber Reinforced Polymer (GFRP) composites are increasingly favored over metal in transportation and construction due to their advantageous properties. Despite these benefits, GFRP’s low fire resistance remains a significant drawback. Recent research in Indonesia has identified a novel approach to this challenge, utilizing the country’s abundant pumice resources. A study focused on the fire-retardant potential of 200-mesh pumice from Mount Rinjani, testing concentrations ranging from 2% to 10% by weight in GFRP composites. The results indicate that a 10% concentration of pumice not only enhances the fire resistance but also optimally increases the ignition time and reduces the burning rate. The pumice contributes to fire protection by forming a char layer around the composite, acting as a thermal barrier that slows combustion and shields the interior. This finding underscores the potential of Mount Rinjani pumice as an effective flame-retardant additive for GFRP composites, promising enhanced safety in fire-prone environments.
