Description
技术领域
本发明涉及一种纳米TiO2改性碳纤维/环氧树脂复合材料的方法,具体属于碳纤维增强环氧树脂复合材料技术领域。
技术背景
碳纤维增强环氧树脂复合材料具有比强度高、比刚度大、结构可设计等许多优点,广泛应用于航空航天、交通、体育设施等领域,该材料用以代替钢材等传统结构材料已成为一种发展趋势。然而碳纤维增强环氧树脂复合材料的安全性成为其首要考虑因素之一。在使用过程中,碳纤维增强环氧树脂复合材料往往会由于长期载荷或自然环境而产生损伤以至破坏情况,其中疲劳损伤为其主要破坏形式之一。因此,对碳纤维增强环氧树脂复合材料的疲劳性能进行研究显得极为重要。
近年来,向环氧树脂基体中加入各种填充物进行增强改性已经成为一项行之有效的措施。纳米粒子尺寸界定在1~100 nm之间,纳米粒子具有极高的比表面积,而且表面活性非常大。环氧树脂与纳米粒子在界面上形成了远大于范德华力的作用力,因此有较好的相容性,形成了非常理想的界面。在环氧树脂受到作用力时可产生引发微裂纹吸收能量的作用,从而大大提高材料的力学性能,达到增韧的目的。另外,纳米粒子的加入还可提高环氧树脂的耐磨性、拉伸强度、冲击强度、热分解温度等,使环氧树脂复合材料的物理性能大大增强,尤其是疲劳性能。董元彩等将环氧树脂用丙酮溶解,然后加入经偶联剂表面处理的纳米TiO2,搅拌分散均匀。加入40 %环氧树脂质量的聚酰胺,混合均匀后于100 ℃固化1 h得到环氧树脂复合材料。张毅等先将除去表面杂质的炭纤维丝置于硝酸溶液中,经磷酸二氢铵浸泡,然后煅烧,再采用双氧水浸泡氧化获得活性炭纤维丝,最后将其放入添加有纳米TiO2的环氧树脂中浸渍,得到表面负载纳米TiO2的改性活性炭纤维丝。邓超月在制备碳纤维/环氧树脂基掺杂钦的太赫兹吸波材料时,采用分散剂羟丙基甲基纤维素(HPMC)作为短切碳纤维在环氧树脂中的分散剂,降低了碳纤维之间的团聚程度。采用溶胶-凝胶法制备的TiO2、Fe-TiO2和BaTiO3纳米颗粒改善了短切碳纤维/环氧树脂复合材料的吸波性能。LichunMaa等通过水热和超临界方法获得了碳纤维表面上二氧化钛纳米棒(TiO2 NRs)的生长。超临界水改善了生长效率并促进了TiO2 NRs更紧密地进入CF表面,使得粗糙度和可湿性明显增加,且纤维的拉伸强度没有降低,复合材料的界面剪切强度(IFSS)和冲击强度提高。Rusheng Yuan等通过使用环氧树脂作为TiO2和活性碳纤维之间的粘合剂,然后在460℃和N2气氛下煅烧2小时制备负载在活性碳纤维上的TiO2,以实现表面积和孔结构的控制,达到造纸废水中COD的有效光降解。上述报道生产的成本较高,工业化生产有一定难度。基于此,本发明在对纳米TiO2进行活化处理,提高了其在环氧树脂中的分散性和相容性,改善了与环氧树脂的界面性能,并且利用简单、低成本的浇注成型和手糊成型方法,来制备具有高力学性能的纳米TiO2改性碳纤维/环氧树脂复合材料。
发明内容
针对现有碳纤维/环氧树脂复合材料的不足,本发明提供一种纳米TiO2改性碳纤维/环氧树脂复合材料的方法。
本发明一种纳米TiO2改性碳纤维/环氧树脂复合材料的方法采用KH-550硅烷偶联剂活化处理的纳米TiO2改性碳纤维/环氧树脂复合材料,具体步骤如下:
步骤1:纳米TiO2的活化处理
用无水乙醇分别清洗纳米TiO2三次后,加入KH-550硅烷偶联剂,经搅拌混合均匀后,再超声处理2 h,分别用无水乙醇清洗3次,再在80 ℃下干燥处理,得到活性纳米TiO2,其中KH-550硅烷偶联剂的用量为纳米TiO2质量的5%以内;
步骤2:纳米TiO2改性碳纤维/环氧树脂复合材料
控制活性纳米TiO2用量为环氧树脂质量分数的6%以内,将活性纳米TiO2分别加入到环氧树脂中,搅拌均匀后超声处理1 h,冷却后加入二乙烯三胺,搅拌均匀后,得到环氧树脂胶;其中,二乙烯三胺的用量为环氧树脂质量分数的10%;
将环氧树脂胶迅速淋浇在铺有1~2层斜纹碳纤维布的模具中,然后开始刮涂;刮胶过程中采用S型刮胶法,使环氧树脂胶浸透碳维纤布,并刮去直径1 mm以上的气泡;其后,继续铺放下一层斜纹碳纤维布,并立即刮涂环氧树脂胶,每层刮涂的环氧树脂胶的用量为碳纤维布质量的50±5%;重复刮涂环氧树脂胶和铺放碳纤维布,共计铺设8层碳纤维布后,在其上再铺放一块脱模布,用光滑刮板刮去多余的树脂并尽量除去树脂中肉眼可见的气泡,盖上玻璃板一块;其后,先将盖好玻璃板的复合材料在常温下固化24 h脱模,然后再在120 ℃下后固化2 h除去复合材料的内应力,得到纳米TiO2改性碳纤维/环氧树脂复合材料。
本发明的有益效果:
本发明方法制备工艺简单,生产成本低,成型可操作性好,复合材料的抗疲劳性能优异。通过改变纳米TiO2含量与偶联剂含量来调节纳米TiO2改性碳纤维/环氧树脂复合材料的疲劳性能,制备的复合材料有很好的抗疲劳性能,当TiO2含量为6%、应力水平为0.7时,复合材料的lg N值达到4.88;当偶联剂含量为5%、应力水平为0.7时,复合材料的lg N值达到5.15;当加载频率为15 Hz、应力水平为0.7时,复合材料的疲劳寿命最长。环氧树脂基体含量高,复合材料的加工性能好,可以制备成所需要的形状。

步骤2:纳米TiO2改性碳纤维/环氧树脂复合材料
控制活性纳米TiO2用量为环氧树脂质量分数的6%以内,将活性纳米TiO2分别加入到环氧树脂中,搅拌均匀后超声处理1 h,冷却后加入二乙烯三胺,搅拌均匀后,得到环氧树脂胶;其中,二乙烯三胺的用量为环氧树脂质量分数的10%;
将环氧树脂胶迅速淋浇在铺有1~2层斜纹碳纤维布的模具中,然后开始刮涂;刮胶过程中采用S型刮胶法,使环氧树脂胶浸透碳维纤布,并刮去直径1 mm以上的气泡;其后,继续铺放下一层斜纹碳纤维布,并立即刮涂环氧树脂胶,每层刮涂的环氧树脂胶的用量为碳纤维布质量的50±5%;重复刮涂环氧树脂胶和铺放碳纤维布,共计铺设8层碳纤维布后,在其上再铺放一块脱模布,用光滑刮板刮去多余的树脂并尽量除去树脂中肉眼可见的气泡,盖上玻璃板一块;其后,先将盖好玻璃板的复合材料在常温下固化24 h脱模,然后再在120 ℃下后固化2 h除去复合材料的内应力,得到纳米TiO2改性碳纤维/环氧树脂复合材料。
