摘要
通过对PMI泡沫/3218-1环氧树脂夹层结构进行湿热处理,测定夹层复合材料的吸湿、脱湿曲线,研究湿热对夹层复合材料的吸湿性能的影响,同时对湿热循环处理前后的夹层复合材料试样进行力学性能和介电性能的测试,以研究湿热循环对两种PMI泡沫/3218-1环氧树脂夹层结构的吸湿性能、力学性能及介电性能的影响。
With hygrothermal cycling on PMI foam/ 3218-1 epoxy sandwich structure,the absorption curves and drainage curves were tested,and the effects of hygrothermal condition on foam cored sandwich structure were studied.The mechanical and dielectric properties of foam cored sandwich structure in dry and wet conditions were also investigated,and the effects of hygrothermal cycling on the two types of foam cored sandwich structure were analysed.
