摘要
对不同成品密度下玻纤增强硬质聚氨酯泡沫塑料体系的微观结构及力学性能进行了研究。扫描电子显微镜观察发现,在不同成品密度下,玻纤与聚氨酯基材的界面结合情况不同,中等密度(0.3g/cm^3)的有效结合面积大于低密度与高密度的。界面结构参数计算及力学性能测试表明,中等密度下的界面结构参数最大,且压缩强度和冲击强度增加率也最大。
The effect of different product densities on the microstructure and mechanical properties of glass fiber reinforced rigid polyurethane foam was investigated. The SEM results showed that the joints between glass fiber and polymer resin were different with the different product densities. It was demonstrated that the area of the joints with medium density was more than others. The interfacial structure parameters and mechanical properties also showed that the interfacial structure parameter was most and the compression strength and impact strength of PUR/GF with medium density were increased most.
