| 摘 要： | 采用八(γ-氯丙基)多面体低聚倍半硅氧烷(T8)改性氰酸酯树脂(CE)制备了系列CE/T8复合材料。研究了复合材料的冲击性能、动态热力学性能、热稳定性能以及断面形貌。结果表明:T8的加入能明显提高复合材料的冲击性能,当加入10%的T8时,复合材料的冲击强度较纯CE提高了12.29 kJ/m2;复合材料在高温阶段(大于500℃)的热稳定性与纯CE相比有一定提高,有助于改善CE的阻燃性能;T8的加入使复合材料的玻璃化转变温度和储能模量均有所降低。 |

| Abstract: | Cyanate ester(CE) resin was modified by octachloropropyl polyhedral oligomeric silsesquioxane(T8) to get a series of CE/T8 composites.The impact strength,dynamic mechanical properties,thermal stability properties,and morphology of fracture surfaces of the composites were studied.The results show that the addition of T8 improves the impact strength of the composites significantly,when T8 content is 10%,the impact strength of the composite increases by 12.29 kJ/m2 compared with that of neat CE;the moderate enhancement in thermal stability properties of CE/T8 composites in high temperature range(>500℃) is helpful to improve the flame retardance of CE resin;the addition of T8 decreases both glass transition temperature and storage modulus of CE/T8 composites. |
