摘　　要：利用TDE - 90环氧树脂与 4 5 0 1A双马来酰亚胺树脂共混体系 ,获得了适于缠绕成型和手糊成型的高性能树脂基体。通过对粘度曲线、凝胶特性曲线及DSC分析确定了成型工艺。共混树脂与TDE - 85环氧树脂、4 5 0 1A树脂的浇铸体及相应复合材料性能的比较 ,表明共混树脂具有较好的工艺性、较低的介电损耗 ;在 15 5℃时 ,其强度、模量的保留率均高于TDE - 85环氧树脂。共混复合材料适合于高温、高速机载雷达罩生产。A new resin suitable for winding and hand lay up molding for high performance composites in aerospace application has been developed by using TDE-90 epoxy compound and 4501A bismaleimide.The formation technology was worked up by analyzing viscosity profile, gel characteristics and differential scanning calorimeter (DSC).The new resin compared to TDE-85 resin,4501 A casting and their composites has appropriate technics and lower dielectric loss. The remaining ratio of strength and modulus is higher than TDE-85 epoxy's at 155℃.And it fits to high performance radome.
