Experimental Thermal Behavior of Fibrous Structures for High-Performance Heat Resistant Fire Curtains

Fibrous materials are often used in the manufacturing of fire protection devices such as curtains. Their optimization and improved performance is still a topic interest. The present work aims to develop test new combination fibers arranged various 2D 3D patterns with coatings. For this purpose, basalt were added into glass fiber fabric, wires shape memory material (SMM) inserted fabric create air pockets induced by temperature. In curtains, base structure basket pattern, all combinations tested without waterborne polyurethane (WPU) coating inorganic materials. Three different tests selected characterize thermal behavior: resistance, ignitability, smoke production. Fiberglass proved be best provide resistance outer surface temperature below 650 °C at end tests. SMM provided good during initial stages test, but excessive deformation reduced strength resulted sudden failure structure. Basalt contribute reduction It was observed an improvement up 10% capacity between 1MIX2 (glass coating, MIX2) commercial curtain evaluated, Commercial3 steel coating).
