复合材料或者高分子合金领域,下面一段话翻译成英文
|
|
| 采用DMA和TGA对CMC/E44、CMC/E51、CMC/CNTs/E44和CMC/CNTs/E51复合材料的性能进行研究,分析工艺条件对性能的影响。研究表明工艺条件对固化物性能影响显著,一定程度上可以媲美于物理共混或者化学改性。工艺优化后所获得的E51环氧树脂固化物的Tg与目前文献报道该体系的最高Tg相当,而分解温度(T5)明显高于文献报道的该体系的数据。CNTs对E44和E51环氧树脂固化物性能的影响并不相同,总体来说CNTs有利于提高Tg,但是对T5影响较小,能否发挥这种效果依赖于CNTs的分散性。对E51环氧树脂,虽然单独使用CMC和CNTs都不能提高Tg,但是同时使用CMC和CNTs却能够增加树脂固化物的Tg。 |

| The properties of CMC/E44, CMC/E51, CMC/CNTs/E44 and CMC/E51 / CNTs composite materials performance are studied, and the effect of process conditions on the properties is analysed by using DMA and TGA. Researches show that process conditions has significant effects on the curing performance, which can match with physical blending and chemical modification to some extent. After process optimization, the Tg of the obtained E51 epoxy resin curing can match with the highest Tg of this system reported in the literatures, and the decomposition temperature (T5) is significantly higher than that of this system reported in the literatures. The effect of curing performance of CNTs on the E51 and E44 is not the same. In general, the influence of the CNTs are beneficial to improving the Tg, but less affecting the T5. It depends on the dispersion of CNTs that the the effect can act or not. For the E51, individually using the CMC or CNTs cannot improve the Tg, but together using the CMC and CNTs will increase the Tg of resin condensate. |
