泡沫铝填充铝管具有高强轻质特性,其轴向承载性能优异,但是服役过程中环境温度和载荷方向多样化,其极端环境下的径向承载能力成为关键瓶颈。为了探究管壁厚度和服役温度对泡沫铝填充铝管径向承载能力的影响,本文选取泡沫铝、空心铝管和泡沫铝填充铝管3种试样,开展了管壁厚度1~3mm和服役温度-100~600℃条件时的准静态径向压缩实验研究,分析载荷-位移曲线、变形模式和吸能规律,揭示泡沫铝与铝管之间相互作用对整体结构承载能力的强化机制。研究结果表明,填充泡沫铝通过提供内部支撑,有效改变了空铝管的变形模式,显著增强了铝管的径向承载和能量吸收能力,并且强化效果受服役温度影响显著,低温会提高材料的硬度和脆性,增大相互作用从而提高承载能力,高温则提升了材料的软化效果,导致结构强度和吸能效率下降。研究结果可为航空航天、武器装甲等军事装备在复杂热-力耦合场景下的轻量化抗冲击结构设计提供实践支撑和理论指导。
Foam-filled aluminum tubes
possess high-strength and lightweight characteristics
demonstrate outstanding axial load-bearing performance.However
their radial compressive capacity under extreme environmental conditions becomes a critical limitation due to varying service temperatures and multi-directional loading during operation. To investigate the influence of cladding temperature and service temperature (-100°Cto 600°C) on radial bearing capacity
this study conducted quasi-static radial compression tests on three specimen types (pure aluminum foam
hollow aluminum tubes
and foam-filledaluminumtubes) with cladding thicknesses of 1-3 mm. Through analysis of load-displacement curves
deformation modes
and energy absorption characteristics
the reinforcement mechanism oftheinterfacial interaction between aluminum foam and tube was revealed. Results indicate that the foam filler effectively modifies the collapse mode of hollow tubes by providing internal support
thereby significantly enhancing radial load capacity. This reinforcement exhibits strong temperature dependence:low temperatures increase material hardness and brittleness
enhancing load-bearing capacity through intensified interactions
whereas hightemperatures promote softening
degrading structural strength and energy absorption efficiency.These findings provide both theoretical guidance and practical
