摘　　要：玻璃钢复合材料主要成分为玻璃纤维和树脂,其制品在受热状态下会发生复杂的物理化学变化,相应的物性参数也随之会有较大变化,进而影响材料结构内部的温度分布;对其受热状态下的变化过程进行研究,给出相应的物性参数变化模型;制备玻璃钢试样进行风洞条件下的烧蚀试验,测量试样背面温升,与应用物性参数变化模型进行的仿真计算结果较为吻合,表明模型构建符合工程实际。Fiber reinforced plastics（FRP） consist of two major components： glass fiber and organic resin. Significant changes in FRP’s physical properties can be found as it goes through a series of physical and chemical evolution under heating conditions,which would further influence the internal temperature distribution of the material.Models regarding the changes in FRP’s physical properties can be set up by studying this process under heating. Using FRP samples,the cool-side temperature was recorded during arc-jet tests,which can be further compared with the results of the simulated calculations from the model. Since the calculated and the arc-jet results match each other very well,this model is suggested to be reliable for the engineering reality.
