| 摘 要： | 采用NH3等离子体对Kevlar-49 S500织物进行了表面改性,处理工艺条件为74.9Pa/113W/14.3分钟.研究结果表明改性后的Kevlar-49 S500织物增强的3234环氧树脂复合材料层间剪切强度提高了26.6%,T型剥离强度提高了22.9%;改性后的纤维表面粗糙度明显增大,与水的接触角降低;T-剥离试样断口的微观分析发现Kevlar纤维/3234环氧界面的破坏方式为纤维本体破坏.

| Abstract: | The Kevlar-49 fabric was modified with NH3 plasma under the conditions of 74.9Pa/113W/14.3min.The results show that the interfacial shear strength of the Kevlar-49/3234 epoxy composites is improved by 26.6% than that of untreated,and the T-peel strength by 22.9%.The mean surface roughness is significantly enlarged and the contact angle with water is lowered.SEM micrographs of T-peel fracture surface of Kevlar-49 S500/3234 epoxy composite made from NH3 plasma treated fibers showed that the fracture mode was ... |
