摘要
通过大量试验重点研究了硬质聚氨酯泡沫塑料约束条件下的抗压性能,给出了多种不同表观密度硬质聚氨酯泡沫塑料约束条件下抗压缩应力-应变关系,分析了硬质聚氨酯泡沫塑料抗压性能随表观密度变化的规律,为工程结构试验研究与数值分析计算提供了基本依据。
The restricted compressed performance of PU rigid foam is researched in this paper. It shows the stress-strain relations of PU rigid foam whice has the different apparent densities. It analyzes the varied rules of its affined constringent performance according to its apparent densities. This paper gives the references on the scientific fields of research and other fields.
