Research Progress of Metal/Carbon Fiber Composites Reinforced Mixed Thin-walled Pipe

薄壁结构广泛应用于汽车、飞机等机械系统的承力部件中。金属碳纤维增强复合材料混合薄壁管兼顾了复合材料轻质与高吸能性,以及金属成型与连接工艺可靠等双重特点,是实现碳纤维复合材料替代金属结构的理想过渡性材料。笔者从混合薄壁管在不同载荷方式下的吸能性分析、失效模式以及影响因素等方面进行了综述。分析表明,通过缠绕或卷绕工艺制成的金属碳纤维增强复合材料混合薄壁管通过合理设计与工艺控制,可以实现对于金属薄壁管的有效替代。

Thin-walled structures were widely used in mechanical systems such as automobiles and airplanes.Metal-carbon fiber reinforced composites(CFRP)hybrid thin-walled tube takes into account the dual characteristics of light weight,high energy absorption and reliable metal forming and joining process.It is an ideal transitional material to replace metal structure with CFRP.The energy absorption analysis,failure modes and influencing factors of hybrid thin-walled tubes under different load modes were reviewed.The analysis shows that the metal-carbon fiber reinforced composite thin-walled pipe made by winding or rolling process can be effectively replaced by the metal thin-walled pipe through reasonable design and process control.
