摘要
研究了不同的胶接工艺对于复合材料胶接性能的影响。对于已经固化的复合材料,对比了使用SY-D15表面处理剂前后胶接性能的变化。结果表明:SY-D15表面处理剂不仅能够显著提高胶接试样的剪切强度,而且对于提高复合材料胶接体系的剥离性能也有明显的作用。复合材料的树脂基体对胶接性能具有显著的影响,增韧的环氧基复合材料和环氧胶黏剂之间的粘接效果最好。碳纤维预浸料和胶黏剂之间的共固化取得了极好的胶接性能。
Influence of different bonding process on performance of bonded composite joints was described in this paper. Performance of bonded joints for cured composite was compared between joints with and without SY - D15 surface pretreatment agent. Test results show that SY - D15 surface pretreatment agent can obviously improve the shear shrength of cured composite bonding joints as well as their anti-peeling properties. The base resin of composite has notable influence on bonding performance. The toughened epoxy based composite has the best bonding performance with epoxy film adhesive. By cocuring between carbon fiber prepreg and adhesive, excellent bonding performance can be obtained.
