摘要

本文介绍了实验和数值研究，主要目的是探讨铝/CFRP 混合薄壁管在压缩条件下的挤压行为。特别是考虑了 8 层、10 层和 12 层复合材料的铝管/CFRP 管，并通过准静态挤压实验研究了其能量吸收特性。为研究铝管/CFRP 管的轴向挤压响应和损坏行为，开发了一个显式有限元（FE）模型。根据实验数据进行验证后，应用所开发的有限元模型分析了层数和加载角度对不同管材配置的破坏机制和能量吸收指标的影响。所获得的结果为铝管/CFRP 管在破碎条件下的实用能量吸收解决方案提供了宝贵的见解，从而促进了相关行业的长远发展。

Crushing performance and energy absorption characteristics of aluminum/CFRP hybrid thin-walled tubes: Experimental and numerical investigations

This paper presents both experimental and numerical studies with the main purpose of exploring the crushing behavior of aluminum/CFRP hybrid thin-walled tubes under compression conditions. In particular, aluminum/CFRP tubes with 8, 10, and 12 layers of composites are considered, and the energy absorption characteristics are examined by quasi-static crushing experiments. An explicit finite element (FE) model is developed to investigate the axial crushing response and damage behavior of aluminum/CFRP tubes. Following validation against the experimental data, the developed FE model is applied to analyze the effects of number of layers and loading angles on the failure mechanism and energy absorption indexes of different tube configurations. The obtained results provide valuable insights into a practical energy absorption solution for aluminum/CFRP tubes subjected to crushing conditions, thereby contributing to the long-term development of the related industry.

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
