使用红外光谱、同步热分析和动态热力分析（DMA）对氰酸酯（CE）树脂及其复合材料在DMA测试前后结构和性能的变化进行了研究，考察DMA测试对其结构和性能的影响。结果表明：在高温下，力的作用是改变CE及其复合材料结构的主要因素DMA测试过程的高温会使氰酸酯树脂进一步固化，从而提高树脂及复合材料的储能模量；高温和力的共同作用会使纯CE树脂的链段长度分布变宽，使CE／ZrO2复合材料界面相与基体相的内耗峰融合。
Some changes of structure and properties of cyanate ester （CE） resin and its composite before and after dynamic mechanical analysis（DMA） were studied by fourier transform infrared（FT-IR）, thermogravimetric differential scanning calorimeter （TG-DSC） and dynamic mechanical analysis （DMA）, and the effect of DMA test on structure and properties was investigated. The results show that the force was the main factor to influence the structure of CE resin and its composite at high temperature. The high temperature during DMA test could make CE rein solidify further, thus to increase the storage modulus of resin and its composite. The interaction of high temperatures and force made the segment distributing of the pure CE resin broadened and the damping peak of the interface phase and the matrix phase of the CE/ZrO2 composite fused.
