摘要

聚合物基复合材料(PMC)和金属基复合材料(MMC)系统的增材制造(AM)为降低航空航天飞行器的质量提供了新的机遇。这些解决方案还有可能降低低温地面应用的成本。为了满足这一需求,本文探讨了三种 AM 材料在 20 K 温度下的机械特性:尼龙基 PMC PA840-GSL,以及两种铝基 MMC A6061-RAM2 和 AlSi10Mg。首先详细介绍了用于机械测试的低温加速疲劳试验机(CRAFT)。其次,得出了添加制造的 AlSi10Mg 合金和 A6061-RAM2 的极限拉伸强度和弹性模量。第三,除了分析扫描间距等加工参数对机械性能的影响外,还收集了添加制造的 PMC 液氢罐成分的机械性能。A6061-RAM2 表现出优异的机械性能,建议用于结构应用。PA840-GSL 扫描间距的变化导致机械性能下降。

Ultimate Tensile Strengths and Elastic Moduli at 20 K of Additively Manufactured PA840-GSL, A6061-RAM2, and AlSi10Mg
The additive manufacturing (AM) of polymer matrix composites (PMCs) and metal matrix composites (MMC) systems presents novel opportunities for reducing the mass of aerospace vehicles. These solutions also have the potential to reduce the cost of terrestrial applications where cryogenic temperatures are present. To address this need, this paper explores the mechanical characterization of three AM materials at 20 K: a nylon-based PMC PA840-GSL, and two aluminum-based MMCs A6061-RAM2 and AlSi10Mg. A Cryogenic Accelerated Fatigue Tester (CRAFT) used for the mechanical testing is first detailed. Next, ultimate tensile strengths and elastic moduli of the additively manufactured AlSi10Mg alloy and A6061-RAM2 are obtained. Third, the mechanical performance of an additively manufactured PMC liquid hydrogen tank constituent is collected in addition to an analysis on the effect the processing parameters, such as scan spacing, have on the mechanical behavior. A6061-RAM2 exhibited superior mechanical performance and is recommended for structural applications. Variation of PA840-GSL scan spacing resulted in decreased mechanical performance.
