摘要
煤沥青原料的纺丝,是碳纤维制造过程中加工成型的关键步骤。在纺丝过程中,要严格控制煤沥青熔体的粘度、纺丝温度、压力、卷绕速度等主要参数。这些参数均为熔体的流变性能所控制。因此,研究煤沥青熔体的流变性能,从理论上和实践上对煤沥青纺丝都有重要的指导意义。
The spinning of coal tar pitch raw material is key procedure of shaping in manufacturing carbon fiber.The main parameters of viscosity, spinning temperature, pressure and winding velocity for coal tar pitch fluid should be rigidly controlled during spinning.Those parameters are all controlled by rheological behaviour of fluid. Thus; study ofthe rheological behaviour of coal tar pitch fluid is of guide importance to the spinning of coal tar pitch in theory and practice.
