PIPD纤维表面改性及其复合材料界面性能研究
发布时间：2021-04-23 16:50
PIPD或M5纤维是具有高拉伸强度的纤维材料,具有如能量吸收等优越的性能,可以应用到对重量要求较高的领域。PIPD纤维具有突出的压缩性能,使其在结构方面的应用可扩展到宇航、航海、汽车和制造工业等诸多领域。然而,PIPD纤维光滑而惰性的表面导致纤维与基体的界面粘接作用较弱。因此,研究人员提出大量的表面改性方法克服这一缺点,从而提高复合材料的界面和力学性能。在本项工作中,提出了一种非剧烈条件下在PIPD纤维表面接枝有机/无机纳米材料的方法,在大幅提高界面与力学性能的同时保持了PIPD纤维原有的拉伸强度。将PIPD表面硝酸化处理后引入了多壁碳纳米管,并研究了酸化处理和接枝方法对纤维性能的影响。对在不同浓度、时间、温度下酸化处理的纤维强度作出评价,获得了不损伤纤维的最佳表面处理条件。进一步,接枝多壁碳纳米管增加了纤维与树脂的接触面积和机械啮合,将PIPD/环氧的界面剪切强度从25.13MPa提高到40.63MPa,提高了62%。接枝多壁碳纳米管后的纤维表面能从34.23 mJ/m2提高到52.04 mJ/m2,提高了52%。同时,将拉伸强度的损失控制...
