  • 摘要: 纤维增强热塑性树脂基复合材料与金属的异质构件在轻量化现代装备中的应用日趋广泛,实现异质构件优质、高效、可靠的连接具有重要的学术意义和工程应用价值. 详细综述了异质接头激光连接原理和界面结合机制,以及连接界面结合强度增强方法和激光连接工艺对连接接头抗剪强度的影响. 通过增强机械结合和化学键结合,同时采用控制激光热输入、施加压力、填充树脂材料等措施抑制缺陷的产生,接头抗剪强度已可以满足工业应用对静载强度的要求. 同时展望了纤维增强热塑性树脂基复合材料与金属激光连接技术的发展趋势.

     

    Abstract: The structure composed with fiber reinforced thermoplastic composites and metal is effective to realize lightweight in the modern equipment manufacturing. Therefore, it is of great academic significance and practical value to achieve high quality, efficient and reliable joining in between. This paper reviews the recent research achievement of laser joining of fiber reinforced thermoplastic composites and metal at home and abroad. The laser joining principle, the bonding mechanism of interface as well as its strengthening methods, and the influence of laser joining parameters on shear strength were introduced in detail. The shear strength has satisfied the requirement of industrial application by using mechanical bonding and chemical bonding strengthening methods as well as avoiding joining defects through controlling the heat input, providing the clamping pressure, and using additional resin. Finally the tendency of development in the near future is predicated.
