Ablation resistance and mechanical properties of polyurethane‐based composites containing different amounts (up to 5 wt%) of organoclay were correlated with the morphological characterization. The crosslinking density of the polyurethane increased with the amount of organoclay. At low concentration (up to 1 wt%), the organoclay was well exfoliated, while at higher concentration, both exfoliated and intercalated platelets were found. A linear correlation was observed between the tensile test and the concentration of organoclay. Erosion velocity decreased 40% with the incorporation of 5% of organoclay. POLYM. ENG.

有机粘土增强聚氨酯的烧蚀性能

含有不同量（最高5 wt％）有机粘土的聚氨酯基复合材料的抗烧蚀性和机械性能与形态表征相关。聚氨酯的交联密度随有机粘土的含量而增加。在低浓度（至多1 wt％）下，有机粘土被充分剥落，而在较高浓度下，被剥落和嵌入的血小板均被发现。在拉伸试验和有机粘土的浓度之间观察到线性相关性。随着5％有机粘土的加入，侵蚀速度降低了40％。POLYM。ENG。SCI。，60：630–635，2020.©2020塑料工程师协会
