Abstract

Preparing large-sized, high-performance carbon fiber reinforced aluminum matrix (CF/Al) composite ring components presents significant challenges in the aerospace industry. This study introduces an innovative fabrication method based on indirect extrusion (IE) for CF/Al composite ring components. The influence of the preform structure on the molding quality was investigated, elucidating the alloy liquid infiltration mechanism during the IE process. Additionally, the mechanical properties and failure mechanisms were systematically analyzed. The results showed that the IE composites had better forming quality with a 15% increase in tensile strength and a 17% increase in shear strength compared to composites prepared by direct extrusion (DE). In addition, based on the area calculation under the stress–strain curve, the tensile and shear energy absorption capacities of IE composites were improved by 98% and 73%, respectively. This process provides a solid foundation for the high-quality preparation and application of composite ring components in advanced aerospace engineering.

间接挤压法制备连续碳纤维增强铝基复合材料环件，提高其强度和韧性

制备大尺寸、高性能碳纤维增强铝基（CF/Al）复合材料环部件是航空航天工业面临的重大挑战。介绍了一种基于间接挤压法（IE）的CF/Al复合材料环件制造方法。研究了预制体结构对成型质量的影响，阐明了IE成形过程中合金液的渗透机理。并对其力学性能和破坏机理进行了系统分析。结果表明，与直接挤压（DE）制备的复合材料相比，IE复合材料的拉伸强度提高15%，剪切强度提高17%，具有更好的成形质量。此外，通过应力应变曲线下的面积计算，IE复合材料的抗拉和剪切吸能能力分别提高了98%和73%。该工艺为复合材料环件的高质量制备和在先进航空航天工程中的应用奠定了坚实的基础。
