Processing carbon fiber reinforced thermoplastic parts includes heating to form the thermoplastic matrix. The needed heat can be applied externally or internally to the preform. One possibility to generate intrinsic heat involves the use of carbon fibers as a resistive element to induce joule heat. So far, most research efforts have been based on contacting continuous carbon fibers on both ends to melt the thermoplastic matrix of a pre-impregnated preform. The objective of this project is to use a dry hybrid yarn textile in a one-step process to impregnate and rapidly consolidate the dry textile in less than a minute. The desired molding process is based on joule heating of carbon fibers due to an applied current in the transverse fiber direction. This article focuses on the detection of the involved macroscopic parameters. The first composites produced by means of this new method exhibit a high potential with heating times of 15 s, a void fraction below 1%, and flexural properties comparable to the state of the art.

由再生碳纤维和 PA6 制成的干纺织品的焦耳加热，用于热塑性复合材料的批量生产

加工碳纤维增强热塑性部件包括加热以形成热塑性基体。所需的热量可以从外部或内部施加到预制件上。产生内在热量的一种可能性涉及使用碳纤维作为电阻元件来产生焦耳热。到目前为止，大多数研究工作都是基于在两端接触连续碳纤维以熔化预浸渍预制件的热塑性基质。该项目的目标是在一步过程中使用干式混合纱线纺织品在不到一分钟的时间内浸渍和快速固结干式纺织品。所需的成型工艺是基于碳纤维在横向纤维方向上施加电流而产生的焦耳热。本文重点介绍所涉及的宏观参数的检测。
