摘要
以4,5-环氧环已烷-1,2-二甲酸二缩水甘油酯(TDE-85)/甲基纳狄克酸酐(MNA)体系作为树脂基体,分别以硼酸铝晶须和硼酸镁晶须为增强相,制备了晶须增强复合材料。研究了以不同的偶联剂表面处理的晶须对树脂体系力学性能的影响,并通过扫描电子显微镜(SEM)分析了复合材料弯曲断面的形貌。结果表明支化程度最高的硼酸酯偶联荆(tert-BE4)的表面处理效果最好,硼酸镁晶须/树脂体系的力学性能优于对应的树脂/硼酸铝晶须共混体系。
After aluminum borate whiskers and magnesium borate whiskers were pretreated with different coupling reagents, borate whiskers-reinforced TDE-85 epoxy resin composites were prepared. The mechanical property of the composites were investigated and the morphologies of their fracture surface were detected by scanning electronic microscope （SEM）. The results showed that the most substituted boric ester-type coupling reagent tert-BE4 performs best in pretreating the surface of borate whiskers, the composites reinforced with magnesium borate whiskers were superior in mechanical properties to those with aluminum borate whiskers.
