Flame Penetration and Burn Testing of Fire Blanket Materials Silicone Rubber Coated Fiberglass Fabrics (2)

Silicone rubber coated fiberglass fabric
performed the best of the fabrics tested. Silica aerogel insulation was the top performing insulation material group. The blanket with carbon fiber sandwiching silica aerogel insulation performed best. Horizontal and vertical flame burn tests were conducted on several candidate blanket cover materials. Fabrics coated with polyvinyl chloride, polytetrafluoroethylene and silicone rubber coatings were all found to be immediately self-extinguishing when the flame was removed. Burn damage was confined locally to the heated zone beneath and around the lit torch tip's flame. All flames were immediately self-extinguishing beyond those regions, with zero flame-out times recorded.
