Evaluation of Insulation Materials and Combinations for Bulkhead Fire Protection

摘要

The extensive use of aluminum in the bulkheads and superstructure of Naval vessels has introduced a need for a more effective fire protection system at a lower weight per square foot than traditionally utilized systems. The objectives of this contract were: to study a variety of insulation materials and systems for their fire protection and weight per square foot characteristics; and to evaluate insulation materials and systems properties to assist in the choice of the most efficient material or system for the range of fire protection and weight per square foot criteria. The objectives were accomplished through a combination of extensive computer studies of materials using the HEATING5 computer program and supportive small scale laboratory fire testing using a two foot by two foot furnace. Most studies were conducted using the ASTM-E119 time/temperature curve as the simulated fire. Several types of materials and systems were evaluated, including refractory fiber insulations, opacified particulates, foam, mineral fiber, and intumescent paint coatings.
