Abstract In this study, a hot press co-moulding technique was investigated for the fabrication of hybrid metal/composite components. The manufactured hat-channel beams comprise pre-bent AA5182-O aluminum alloy sheet and laminated glass fiber-reinforced plastic (GFRP) layers. Opto-digital microscopy was used to characterize the microstructure of the co-moulded beams and to investigate linkages between the microstructure and manufacturing process. Furthermore, the mechanical performance of baseline aluminum beams and the hybrid co-moulded beams under quasi-static three-point bending loads was examined. Two different loading configurations were considered to place the hybridized section either adjacent to the loading tup or on the face of the beam away from the loading tup. The results revealed that the greatest benefit was achieved when the composite section was placed on the side in contact with the loading tup, which resulted in an increase in the strength and absorbed energy of 130% and 90%, respectively, for a 20% weight gain.

评估准静态三点弯曲下共模制混合 AA5182-O/GFRP 帽槽梁的失效机制和机械性能

摘要 在这项研究中，研究了一种用于制造混合金属/复合材料部件的热压共模技术。制造的帽形槽梁包括预弯曲的 AA5182-O 铝合金板和层压玻璃纤维增​​强塑料 (GFRP) 层。光电数字显微镜用于表征共模制梁的微观结构并研究微观结构和制造过程之间的联系。此外，检查了准静态三点弯曲载荷下基线铝梁和混合共模梁的机械性能。考虑了两种不同的加载配置，以将混合部分放置在靠近加载塔的位置或远离加载塔的梁的表面上。
