| 摘 要： | 以自行合成的环氧基倍半硅氧烷（POSS）为改性剂，分别对环氧树脂139S/六氢苯酐和环氧树脂BE 188EL/六氢苯酐进行改性，制备环氧树脂/POSS杂化材料。力学性能分析结果表明，两种杂化材料的冲击强度和弯曲强度都有明显的提高，冲击强度分别提高了57.45 %和32.26 %，弯曲强度分别提高了9.23 %和5.07 %。热性能分析结果表明，两种杂化材料在高温时的热残留量都有所提高，分别提高了50.19 %和20.16 %。两种杂化材料的热膨胀系数也得到了降低，即热稳定性得到了提高。

| Abstract: | Two epoxy resin systems （139S and BE 188EL cured with hexahydrophthalic anhydride） were modified with 3 glycidoxypropyl polyhedral oligomeric silsesquioxane cage (POSS) led to POSS/epoxy hybrid materials. The impact strengths of the two epoxy systems were increased by 57.45 % and 32.26 %, the flexural strength were increased by 9.23 % and 5.07 %，and the thermal residual weight increased by 50.19% and 20.16%. Meanwhile, the coefficients of thermal expansion was lowered. |
