The effect of heat treatment of Arselon and Arselon-C polymer yarns in the range 325-400°C on their strength, rigidity modulus, and electrical conductivity followed by carbonization up to 900°C was studied. The minimal strength was shown to correspond to the maximum electrical conductivity at a treatment temperature of ~375°C. The rigidity modulus increased locally if the treatment temperature was increased over 375°C. A hypothesis that the polymer fiber should contain structural units capable of adequately forming carbon phases and ordering them for an efficient transition into carbon fibers was proposed and justified based on an analysis of the fiber mechanical and electrical properties. Results of mechanical tests and electrical measurements were described well in terms of classical and previously proposed models of the fiber as a system, succession, and translation of the fiber properties during heating and carbonization.

研究了在 325-400°C 范围内对 Arselon 和 Arselon-C 聚合物纱线进行热处理对其强度、刚性模量和导电性的影响，然后在高达 900°C 的温度下进行碳化。显示最小强度对应于~375°C 处理温度下的最大电导率。如果处理温度增加超过 375°C，则刚性模量会局部增加。基于对纤维机械和电性能的分析，提出并证明了聚合物纤维应包含能够充分形成碳相并对其进行排序以有效转变为碳纤维的结构单元的假设。机械测试和电气测量的结果在光纤作为一个系统的经典模型和先前提出的模型方面得到了很好的描述，
