Abstract
Glass reinforced polymer (GRP) has been identified as a potential structural for naval superstructures and offshore platforms. Although GRP has been used in commercial and pleasure crafts and other areas for the past 30 years, it has limited applications in the military due to tis flammability. Despite its poor fire resitance, GRP has advantages over metals that include high strength-to-weight ratio, stiffness-to-weight ratio, and excellent corrosion resistance. In marine applications, these advantages could result in lighter naval vessels, better performance and lower cost. The present challenge of GRP manufacturers is to resolve the problems of fire, smoke and smoke toxicity of vinylester or polyester based GRP. It must meet the requirements of military standards and building codes in order to expand the market share over metal alloys and other materials. This paper examines the use of an inorganic coating to improve the fire resistance of vinylester resin based GRP. The selected coating is a totally inorganic system which does not release any organic gases or contribute to the fireload during the fire. The test data will include flame spread index (ASTM E162), smoke generation (ASTM E662), the cone calorimeter test (ASTM E1354), and the Navy Quarter Scale Room Fire Test.
