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. |
