Fire retardancy characteristics of polymeric composite materials

Fire retardancy characteristics of polymeric composite material reinforced by fibers using coating by a fire retardant layer represent antimony tetroxide was studied. A coating layer (4mm) thickness from antimony tetroxide was used as a surface layer to react and prevent spread of flame on surface of epoxy resin reinforced by carbon – Kevlar fibers and exposed this coating layer to direct flame generated from oxyacetylene flame with different exposure distances (10, 15, 20mm) and study how it can protect the substrate . The experimental results showed that a great increment in thermal resistance and flame retardancy after coating by antimony tetroxide as well as rising flame resistance increased exposure distances to flame.
