Abstract:

采用聚甲基丙烯酰亚胺(PMI)泡沫、碳纤维增强环氧树脂(EW220/5258)复合材料面板制备了PMI泡沫夹芯复合材料,研究了PMI泡沫夹芯复合材料、EW220/5258复合材料面板及PMI泡沫芯材的吸湿特性,并讨论了湿热对PMI泡沫夹芯复合材料的压缩性能及介电性能的影响。结果发现:PMI泡沫夹芯复合材料的饱和吸湿时间为96h,饱和吸湿率为1.7%,EW220/5258复合材料面板会对PMI泡沫芯材起到一定的保护作用,阻止水汽进入泡沫,提高PMI泡沫夹芯复合材料的耐湿热性;由于水分子的增塑作用,湿热处理后PMI泡沫夹芯复合材料的压缩强度有所下降,强度保持率约为65.87%,湿热处理初期对其影响较大;湿热处理后,在7~18GHz的测试范围内,PMI泡沫夹芯复合材料的损耗角正切从0.008上升到0.012,介电常数几乎不变。
