摘要Exposure of fibre-reinforced polymeric composites (FRCs) to high temperatures causes the organic resin matrices to soften, undergo thermal degradation and/or ignite, resulting in loss of mechanical integrity of the structure. The most effective technique of fire retardation without affecting the composite’s physical and mechanical properties is the use of surface coatings, which can inhibit or reduce the heat transfer from the fire/heat source to the underlying structure. Conventional intumescent coatings (used for steel structures), when applied on FRCs  provide passive fire protection by slowing down the rate of heat transfer and burning, where most often the polymeric binder used ignites prior to the activation of the intumescent chemicals.  Most often 2-3 mm thick coating is required to provide adequate protection to the flammable polymeric surfaces, which is not a practical solution.  We have polymerised a volatile organophosphorus monomer using UV curing methodology on composite surfaces, hence eliminating any combustible components on the surface. A 0.5 mm thick coating in a cone calorimetric test at 50 kW/m2 prevented ignition, whereas a 0.3 mm thick coating ignited but the time-to-ignition was increased and the peak heat release rate significantly reduced. The coatings did not peel off when subjected to a tape pull test and resisted cracking during a low velocity impact test. The coating however, performed relatively poorly in water-soak tests. Water-soak test performance can be significantly improved however by various hydrophobic modifications without detriment to fire performance.
