摘　　要：以玻璃纤维复合材料(GFRP)夹芯板为研究对象,在考虑热工参数、边界条件等多种条件影响下,运用ABAQUS模拟出标准火灾升温曲线作用下GFRP夹芯板沿厚度方向的温度场仿真模型,并与试验进行对比.通过改变复合材料夹芯板厚度、增加防火板保护和采用悬挂式防火结构等方式,模拟出不同复合材料夹芯板防火结构的温度场结果.改变防火板厚度和隔空距离进行参数优化,得到等效达到船舶防火规范FTP11隔热性要求的防火结构;并降低复合材料夹芯板内部温度,提供多个温度场结果.Taking the glass fiber composite(GFRP)sandwich panel as the research object,considering the influence of thermal parameters,boundary conditions and other conditions,ABAQUS was used to simulate the temperature field simulation model of GFRP sandwich panel along the thickness direction under the action of standard fire temperature rise curve,and the simulation model was compared with the experiment.By changing the thickness of composite sandwich panel,increasing the protection of fire-proof panel and adopting suspended fire-proof structure,the temperature field results of different composite sandwich panels were simulated.Parameters were optimized by changing the thickness and spacing distance of the fire protection board,and the fire protection structure equivalent to the thermal insulation requirements of the ship fire protection code FTP11 was obtained.
