| 摘 要： | 分别以BH-1、2,4,6-三(二甲氨基甲基)苯酚(DMP-30)和2-乙基-4-甲基咪唑(2,4-EMI)作为促进剂,研究了三种不同促进剂对环氧树脂(EP)/酸酐固化体系力学性能和耐热性能的影响;并以此作为复合材料的基体树脂,以玻璃纤维作为增强材料,制备风电叶片用EP基玻璃纤维增强复合材料。结果表明:三种基体树脂及其玻璃纤维增强复合材料均具有优异的力学性能,能够用于风电叶片的制备;其中以BH-1为促进剂的EP/酸酐体系具有最好的韧性和综合力学性能,其最大拉伸强度超过80MPa,断裂伸长率为3.80%。 |

| Abstract: | With BH-1,2,4,6-tris(dimethylaminomethyl)phenol(DMP-30) and 2-ethyl-4-methylimidazole (2,4-EMI) as accelerants respectively,the influences of three different accelerants on mechanical properties and heat resistance of epoxy resin(EP)/anhydride curing systems were investigated. Then with EP/anhydride curing systems as matrix resins and fiberglas as intensifier of composite,so an EP-based composites intensified by fiberglas were prepared used for wind power blades. The results showed that the composite intens... |
