摘要: 碳纤维增强树脂基热固性复合材料(简称“热固性复材”)/金属叠层结构是高端装备常见的结构形式,一体化钻孔是实现叠层结构连接装配的重要环节之一。然而,热固性复材和金属的物化属性差异显著,一体化钻孔时损伤频发,难以满足工程领域的迫切需求。为此,热固性复材/金属叠层结构的高质高效一体化钻孔技术近年来备受关注,学术和工程领域的相关人员开展了大量有价值的研究工作。从热固性复材/金属叠层结构界面区域共切削去除行为、钻孔力热与切屑行为、低损伤钻孔刀具和低损伤钻孔工艺四个方面,综述了叠层结构一体化钻孔技术的研究进展。首先,详细介绍了叠层结构界面区域共切削去除行为在宏观和细观尺度上的研究进程,其次分析了叠层结构一体化钻孔过程中轴向力、钻削温度和切屑的演化行为和变化规律,然后归纳了叠层结构低损伤一体化钻孔刀具的发展历程,进一步阐述了叠层结构一体化钻孔工艺参数、冷却和振动辅助等工艺对钻孔质量的影响机制,最后展望了热固性复材/金属叠层结构一体化切削理论、钻孔技术和钻孔装备等方面的发展机遇和面临挑战。

Abstract: Carbon fiber-reinforced thermosetting composite (“thermoset composite”)/metal stack represents a prevalent structural format in high-end equipment, with one-shot drilling emerging as a pivotal aspect for achieving seamless connection and assembly of these stacks. However, the stark differences in their physicochemical properties often lead to frequent drilling-induced damages, posing a challenge to meeting the pressing demands of the engineering sector. Consequently, the pursuit of high-quality and efficient one-shot drilling technology for thermoset composite/metal stacks has garnered significant attention in recent years, prompting extensive and valuable research endeavors from both academic and engineering circles. This study comprehensively reviews the latest advancements in one-shot drilling technology for stacks, encapsulating four key aspects: the co-cutting removal behavior of the interface region, drilling force, heat generation, and chip behavior, low-damage drilling bits, and low-damage drilling processes. Firstly, the research progression of the co-cutting removal behavior at both macro and micro cutting levels are discussed, detailing the interface region's characteristics. Secondly, the evolution and variation patterns of thrust force, drilling temperature, and chip formation during the one-shot drilling process of stacks are analyzed. Subsequently, the historical development of low-damage one-shot drilling tools for stacks is summarized and the influence mechanisms of drilling process parameters, as well as the effects of cooling and vibration assistance, on hole quality, are elucidated. Lastly, the future trajectory and challenges facing cutting theories, drilling technologies, and process equipment for CFRP/metal stacks are discussed.
