Abstract
En 中文
• Integrated lightweight design framework combining sensitivity analysis, experimental validation, and LCA. • Achieved 11% weight reduction while maintaining stacking strength. • Thermal insulation only slightly reduced (9% ice-melting; 6% temperature-rise). • Lumped capacitance method validated through agreement of R-values from two thermal tests. • Environmental impacts reduced across all categories, including 10%–11% lower global warming potential.
