Abstract

The application of thermoplastic composites has advanced structural lightweight, necessitating effective methods for achieving stable joints. In this study, a laser-ablated graphite film was developed as a novel heating element, introducing an innovative approach to the resistance welding of carbon fiber-reinforced polyamide 66 (CF/PA66) thermoplastic composites. Systematic experiments and analyses verified the performance of the graphite heating element in providing uniform heat and efficient welding during the process. Through systematic experiments and analysis, the graphite heating element demonstrated uniform heat generation and high welding efficiency. The use of this heating element enhanced resin flow and improved the temperature distribution uniformity at the welding interface. Moreover, it eliminated the need for dissimilar metallic materials, thereby reducing stress concentrations and minimizing edge effects during the welding process. This novel heating element shows great potential for resistance welding of thermoplastic composites, offering a groundbreaking solution for joining high-performance and lightweight structures.

新型石墨薄膜加热元件热塑性复合材料的电阻焊接

热塑性复合材料的应用促进了结构轻量化，需要有效的方法来实现稳定的连接。在这项研究中，激光烧蚀石墨薄膜作为一种新的加热元件，为碳纤维增强聚酰胺66 （CF/PA66）热塑性复合材料的电阻焊接引入了一种创新的方法。系统的实验和分析验证了石墨加热元件在焊接过程中具有均匀散热和高效焊接的性能。通过系统的实验和分析，证明石墨加热元件产热均匀，焊接效率高。该加热元件的使用增强了树脂流动，改善了焊接界面温度分布的均匀性。此外，它消除了对不同金属材料的需求，从而减少了应力集中，并在焊接过程中最大限度地减少了边缘效应。这种新型的加热元件在热塑性复合材料的电阻焊方面显示出巨大的潜力，为连接高性能和轻质结构提供了突破性的解决方案。
