摘要

研究了交联聚氯乙烯泡沫塑料的拉伸力学性能和断裂韧性。杨氏模量、屈服强度和断裂韧性数据与开孔泡沫和闭孔泡沫的微观结构关系进行了比较。破坏过程和应力应变响应反映了材料的脆性行为。

Tensile and Fracture Characterization of PVC Foam Cores

Mechanical behavior in tension and fracture toughness of cross-linked PVC foams have been characterized. Young’s modulus, yield strength and fracture toughness data were compared to micro-structural relations derived for open and closed-cell foams. The failure process and stress strain response were indicative of brittle material behavior.
