摘　　要：采用溶液浸渍对炭纤维（ＣＦ）进行了硼改性处理，并在２５００℃下进行石墨化热处理。研究了硼化物溶液浓度及活化剂对炭纤维力学性能的影响，通过扫描电镜观察炭纤维断面的微观结构形态。实验结果表明，ＣＦ硼处理后可以明显提高纤维的模量，适当控制硼化物溶液浓度，可以同时提高强度。HTA 3K carbon fibers were doped with boride by the method of solution soaking.The effect of concentration of boride solution on the mechanical properties of carbon fibers was studied.In addition,the influence of activator on CF modulus was also discussed.Results showed that both the Young's modulus and the tensile strength of CF can be improved significantly at the same time by the method of boron doping with a special concentration of boride solution.
