拉胀泡沫因其独特且增强的性能而继续引起研究人员的兴趣。现有研究证明了制造机制和参数的重要性。然而，热机械参数的差异引起了关于哪些因素主导制造输出质量的争论。本文使用文献中报道的关键参数，提供了对拉胀泡沫生产机制的实验、计算和统计见解：孔隙率；加热时间；和体积压缩比。为了推进对制造参数主导地位的考虑，研究设计和规模都经过优化，以便能够得出统计推论。虽然对于制造领域来说是不寻常的，但这种额外的分析提供了拉胀特性更确凿的证据，并强调了体积压缩比在预测制造过程中泊松比结果方面的至高无上的地位。此外，利用统计结果为那些希望最大化/优化拉胀泡沫生产的人制定关键建议。
Auxetic foams continue to interest researchers owing to their unique and enhanced properties. Existing studies attest to the importance of fabrication mechanisms and parameters. However, disparity in thermo-mechanical parameters has left much debate as to which factors dominate fabrication output quality. This paper provides experimental, computational, and statistical insights into the mechanisms that enable auxetic foams to be produced, using key parameters reported within the literature: porosity; heating time; and volumetric compression ratio. To advance the considerations on manufacturing parameter dominance, both study design and scale have been optimised to enable statistical inferences to be drawn. Whilst being unusual for a manufacturing domain, such additional analysis provides more conclusive evidence of auxetic properties and highlights the supremacy of volumetric compression ratio in predicting Poisson’s ratio outcomes in the manufacture process. Furthermore statistical results are exploited to formulate key recommendations for those wishing to maximise/optimise auxetic foam production.
