| 摘 要： | 采用纳米炭黑填充Lyocell纤维制备碳纤维,并对纤维的结构与性能进行了分析。结果表明:经过不同温度预氧化处理后和最终得到的碳纤维的X射线衍射图谱中都保留着纳米炭黑的特征衍射峰;填充纳米炭黑的Lyocell基碳纤维的力学性能显著提高,填充质量分数10%纳米炭黑的Lyocell基碳纤维强度和模量分别比未填充的提高45%和56%;纳米炭黑填充的Lyocell基碳纤维结构致密、表面光洁,没有明显的裂纹和缺陷。

| Abstract: | Lyocell-based carbon fibers were prepared by using Lyocell fibers filled with nano-carbon black as precursors.The structure and properties of carbon fibers were investigated.The results showed that X-ray diffraction patterns of the resulted car- bon fiber after the pre-oxidization under different temperature kept the characteristic peak of nano-carbon black.The mechanical properties of nano-carbon black filled Lyocell-based carbon fiber were improved considerably.The tenacity and modulus of Lyo- cell-based carbon fiber filled with 10% nano-carbon black by mass fraction were increased by 45% and 56%,respectively,as compared with those of non-carbon black filled Lyocell-based carbon fiber.Moreover,the nano-carbon black filled Lyocell-based carbon fiber had compact structure and smooth surface without any obvious crevices and flaws. |
