* M7 g& x5 w- z7 I【摘要】 用多种预割口实验方法研究了黏土/炭黑/天然橡胶纳米复合材料在静态和动态情况下的抗裂纹增长和耐破坏性能。结果表明,少量纳米黏土的加入能够有效地增加裂纹尖端的钝化支化倾向,从而阻碍裂纹的增长,提高天然橡胶的耐破坏能力;用动态耐切割试验机研究抗崩花掉块性能的结果表明,少量纳米黏土的加入可以提高复合材料抗崩花掉块的能力,改善其耐切割性能;纳米黏土的加入还提高了复合材料的耐磨性能和耐屈挠疲劳性能。
【英文摘要】 Various precut methods were employed to study the cut growth resistance and fracture resistance under static and dynamic conditions of clay/carbon black/natural rubber nano-composites.The results showed that the addition of clay could effectively blunt the crack in the vicinity of the original cut tip and hinder the crack from growing,therefore improved the fracture resistance of natural rubber.Cut and chip tester was used to study the cut and chip resistance and the result showed that cut and chip resistan...
