The Fire Resistance of Transformable Barriers: Influence of the Large-Scale Factor

The paper presents the results of development a multi-layer protective product, which is transformable fire barrier, installed in buildings and structures to limit spread flame, heat flow smoke. Based on simulation eight samples curtains, three promising different compositions were selected, demonstrating resistance loss thermal insulating capacity (I) 30 min. During small-scale tests, it was found that multilayer fabric following composition promising: heat-treated silica fabric, aluminum foil, mineral fiber insulation material, stitched by needle-punching with thread, reinforced fiberglass mesh through basalt seams treated fire-resistant elastic sealant. According standard large-scale experimental study, curtain integrity not less than 60 min, ability 15 min obtained. study assess impact scale factor curtains fire.
