As environmental pollution becomes a serious concern, considerable effort has been undertaken to develop power devices with minimal production of carbon dioxide (CO) and exhaust gases. Owing to this effort, interest in technologies related to hybrid and electric products that use fuel cells has been increasing. The risk of human injuries owing to electromagnetic waves generated by electrical and electronic devices has been also rising, prompting the development of mitigating technologies. In addition, antistatic devices for protecting operators from static electricity have also been considered. Therefore, in this study, we investigated the development of thermoplastic carbon composites containing carbon fibers (CFs) and carbon nanotubes (CNTs). Ultimately, materials with improved mechanical properties (e.g., flexural, impact, and tensile strength properties of about +61.09%, +21.44%, +63.56%, respectively), electromagnetic interference (EMI) shielding (+70.73 dB), and surface resistivity (nearly zero) can be developed by impregnating CFs and CNTs with polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) resins, respectively. The total average mechanical properties of PC and ABS composites increased by 24.35% compared with that of ABS composites, while that of PC composites increased by 32.86% with that of PC and ABS composites. Therefore, in this study, we aimed to develop carbon composites, to take advantage of these thermoplastic resins.
随着环境污染成为一个严重问题，人们已经付出了巨大努力来开发二氧化碳（CO）和废气排放量最小的动力装置。由于这一努力，对与使用燃料电池的混合动力和电动产品相关技术的兴趣不断增加。电气和电子设备产生的电磁波导致人员受伤的风险也在上升，这促使了缓解技术的发展。此外，还考虑了用于保护操作人员免受静电影响的抗静电装置。因此，在本研究中，我们研究了含有碳纤维（CFs）和碳纳米管（CNTs）的热塑性碳复合材料的开发。最终，通过分别用聚碳酸酯（PC）和丙烯腈-丁二烯-苯乙烯（ABS）树脂浸渍CFs和CNTs，可以开发出具有改善的机械性能（例如，弯曲、冲击和拉伸强度性能分别提高约61.09%、21.44%、63.56%）、电磁干扰（EMI）屏蔽（+70.73 dB）和表面电阻率（几乎为零）的材料。PC和ABS复合材料的总平均机械性能比ABS复合材料提高了24.35%，而PC复合材料比PC和ABS复合材料提高了32.86%。因此，在本研究中，我们旨在开发碳复合材料，以利用这些热塑性树脂。
