以糠酮树脂作粘结剂，添加树脂碳微粉、硼类催化剂、短切ＰＡＮ基高强碳纤维，制得了含硼Ｃ／Ｃ复合材料。通过Ｘ射线衍射（ＸＲＤ）、Ｘ射线光电子能谱（ＸＰＳ）等手段，检测了硼、氧化硼在Ｃ／Ｃ中的状态，研究了它们对Ｃ／Ｃ复合材料的催化石墨化作用，分析了石墨化温度、催化剂种类及其用量对石墨化度的影响。结果表明，硼以固溶体的形式存在Ｃ／Ｃ复合材料，通过吸电子断键、代替碳原子消除缺陷等机理形式，使最难石墨化的玻璃碳和纤维碳达到了石墨化。在石墨化温度是２１００℃、催化剂硼用量小于５．０ｗｔ％工艺条件下，玻璃碳基Ｃ／Ｃ的石墨化度达到了８２％，而无催化剂的Ｃ／Ｃ在２５００℃下石墨化度才达到７１％。这表明硼在降低石墨化温度方面有明显作用。
With the furfural ketone resin as binder, resin carbon powder, boron catalyst and chopped PAN-based high-strength carbon fiber were added to prepare boron-containing C / C composites. The state of boron and boron oxide in C / C was investigated by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The catalytic graphitization of C / C composites was also studied. Effect of Graphitization Temperature, Catalyst Type and Amount on Graphitization Degree. The results show that boron exists in the form of solid solution with C / C composites, and the most difficult graphitized glassy carbon and fibrous carbon are graphitized by the mechanism of electron - withdrawing bond breaking and replacing carbon atoms to eliminate defects. The graphitization degree of glassy carbon based C / C reaches 82% under the condition of the graphitization temperature is 2100 ℃ and the amount of catalyst boron is less than 5.0wt%, while the graphitization degree of C / C without catalyst is 2500 ℃. Reached 71%. This shows that boron has a significant effect in lowering the graphitization temperature.
