Abstract
本发明涉及对碳化硅纤维进行处理的方法,所述方法包括如下步骤,所述步骤涉及用含有氢氟酸和硝酸、但不含乙酸的水性酸溶液对纤维进行化学处理,从而移除存在于纤维表面上的二氧化硅并形成微孔碳层。本发明还涉及生产纤维预制品的方法,所述方法包括形成含有经处理的碳化硅纤维的纤维构造物;以及涉及所述预制品在生产由复合材料制成的部件中的用途。
Description
技术领域
本发明涉及碳化硅(SiC)纤维,所述碳化硅纤维在复合材料生产中用作增强物(reinforcement)。
背景技术
对复合材料的优良机械性能(特别是在高温下)进行的探寻,使得采用陶瓷材料作为纤维增强物,从而代替显示出有限的机械强度、并且如果在长时间处于高温下的氧化介质中时对氧化无足够抵抗力的碳。
通常,众所周知的是,在包含纤维增强物的复合材料中,纤维-基质交界面的特性对材料的机械性能有很大的影响。
就包含陶瓷基质的复合材料而言,其显示出可通过如下方法获得令人满意的表现(特别是在冲击和裂纹扩展方面),而无关该基质的陶瓷性质:在基质的陶瓷材料浸润前,在纤维上形成厚度较薄的中间涂层(例如,所述涂层由气相沉积的热解碳制成或由氮化硼制成)。在法国专利FR 2 567 874中描述了此类方法。
然而,优选改善氮化硼或热解碳沉积层与碳化硅纤维之间的结合交界面。还优选能够得到具有增强的机械性能的碳化硅纤维。
已知的是,在碳化硅纤维的表面形成微孔碳表层(superficial layer)在改善室温下的机械性能方面具有益处(US 6579833,WO 2005/007566),并且另外与热解碳沉积层构成良好的结合交界面(WO 2010/076475)。
然而,这些文献中描述的方法使用基于卤代气体的反应性热处理在碳化物表面上生成微孔碳层。因此,从方法本身及用于实施该方法的工具(必须对卤代化合物耐受)两个角度来看,实施该方法很复杂。
此外,一些碳化硅纤维在其表面具有薄的二氧化硅层,可取的是将所述二氧化硅层在任何后续处理之前移除。
由专利申请FR 2640258可知晓对存在于碳化硅纤维表面的二氧化硅进行的化学移除处理。然而,所推荐的处理并不能完全移除存在于纤维表面的二氧化硅层,该层的厚度仅降低至约0.005微米(对应于检测极限)。所述处理由如下物质的使用组成:
氢氟酸的水溶液;
或者,加热条件下的硝酸水溶液;
或者,加热条件下处于精确比例的氢氟酸、硝酸和乙酸(HF3ml+HNO35ml+CH3-CO2H 3ml)的混合物,对应的HF/HNO3摩尔比为1.29。
因此,优选能够具有如下方法:允许在完全移除存在于纤维表面的二氧化硅层的同时,形成微孔碳表层。
由专利申请EP 0855373还可知晓,在生产SiC纤维期间,使用氢氟酸、或者氢氟酸和硝酸的混合物作为对SiC纤维进行洗涤的溶液。然而,由于该洗涤步骤的作用仅在于移除所述生产后存在于纤维表面上的未反应的初始物质的残留物(例如,二氧化硅颗粒),因此,该洗涤步骤并不是化学处理步骤。因而,在这些纤维上并不能形成微孔碳层。此外,该文献仅公开了含有与等含量的HNO3溶液(含有60wt%-70wt%的HNO3)混合的46wt%HF的水性溶液。实施例2因而公开了250ml HF水性溶液与250ml HNO3溶液的混合物。因此,该实施例的酸溶液所具有的硝酸含量为4.76-5.54mol/l、HF含量为约11.5mol/l,即,氢氟酸与硝酸的摩尔比为2.08-2.41。因此,该文献中所述的酸浓度非常强,以至于不能够对反应进行控制。
发明内容
由此,本发明人出乎预料地发现,在水性溶液中组合使用氢氟酸和硝酸、而不添加乙酸,使得能够完全清除存在于碳化硅纤维表面的二氧化硅层,同时能够形成附着至纤维并具有均匀厚度的微孔碳层(例如≤100nm)。由于上述使用并非在纤维生产期间进行,而且不需要移除存在于这些纤维表面的未反应的初始物质,因此不能将该使用比作专利申请EP 0855373所述的洗涤步骤。
此外,该微孔碳层构成了对热解碳层沉积而言的良好结合交界面。
事实上,在该层中,碳并未呈现出任何特定的结构组织。碳为微孔性的,并具有非常高的比表面积(约1500m2/g)以及非常小的孔(孔直径为约1纳米)。此外,当热解碳层沉积在该微孔碳层上时,这两个层形成混合的碳中间相,使得能够提高复合材料的机械特性,特别是在拉伸强度和断裂应变方面。
因此,本发明涉及对碳化硅纤维进行处理的方法,所述方法包括用含有氢氟酸和硝酸的水性酸溶液对纤维进行化学处理的步骤,从而移除存在于所述纤维表面上的二氧化硅并形成微孔碳层,其特征在于,所述水性酸溶液不含乙酸。
本发明人由此发现,与使用单独的各所述酸、以及将所述氢氟酸和硝酸与乙酸组合使用相比,以水性溶液组合使用氢氟酸和硝酸更加有利,因为组合使用氢氟酸和硝酸使得能够完全移除存在于纤维表面的二氧化硅,并形成小于或等于100nm的微孔碳层。因此,组合使用HF和HNO3具有协同作用,现有技术中对该协同作用并无任何暗示。实际上,HF移除存在于纤维表面的二氧化硅,而HNO3使二氧化硅可溶并氧化纤维的碳氧化物和碳化硅,从而能够形成微孔碳层。当单独使用HF时,在二氧化硅的化学形式不可溶时,不可能移除全部的二氧化硅,并且无微孔碳层存在于纤维表面。另一方面,当单独使用HNO3时,将不会有二氧化硅的移除,并因此将不能发生氧化,也不会形成微孔碳层。因此,这两种酸的组合使用对于实施本发明而言是必不可少的。此外,出乎预料地发现,与现有技术中的教导相反的是,乙酸对于覆盖纤维的二氧化硅并没有影响,因此在化学处理步骤中,水性酸溶液中存在的乙酸是多余的。
有利的是,本方法并不是在纤维生产过程中实施,也不作为该过程的洗涤步骤,即,本方法并不是在其表面上具有未反应的初始物质(例如,二氧化硅颗粒)的纤维上实施。因此,本发明所述的方法并非是作为简单的纤维洗涤步骤,而是使得在纤维表面形成微孔碳层。
在本发明的上、下文中可使用的酸的比例取决于微孔碳层的期望厚度、待施加处理的纤维类型(碳化物与碳氧化物的比例、以及碳化物的类型)以及处理温度。在本发明的一个特定实施方式中,特别是在20℃的温度下,本发明所述的水性酸溶液含有的氢氟酸/硝酸的摩尔比小于1.5、优选小于1.2、更优选小于1、甚至更优选小于0.8,特别是大于0.1、优选大于0.15、甚至更优选大于0.2。
通常,优选酸溶液未被过度浓缩,从而能够对可控的侵蚀动力学(attack kinetics)进行管理,并由此形成具有良好可再现性的碳层。
有利的是,在20℃下本发明所述的水性酸溶液含有的硝酸的含量为0.5-5mol/l、优选2-5mol/l、特别是0.5-4mol/l、尤其是2-4mol/l。
因为高于5mol/l时,存在HNO3分子在空间上阻碍HF接近纤维表面、甚至可能阻止反应发生的风险。另一方面,必须存在少量的HNO3,以引发反应。
有利的是,在20℃下本发明所述的水性酸溶液含有的氢氟酸的含量为0.5-4mol/l、优选0.5-3mol/l、特别是0.5-2.5mol/l、更特别是0.5-2mol/l。
HF的量决定了对于给定的HNO3浓度而言的反应动力学。
在本发明的另一具体实施方式中,化学处理步骤在室温下(即,20-25℃)实施。因此,当存在硝酸时,与专利申请FR 2642158中所推荐的相反,化学处理步骤并不是在加热条件下实施。化学处理步骤的持续时间取决于在纤维表面期望获得的微孔碳层的厚度以及所使用的HF/HNO3比例。有利的是,为获得小于或等于100nm的层,这一步骤持续10分钟至5小时、优选3-5小时。
在本发明的又一实施方式中,化学处理步骤在加热条件下(即,在高于室温的温度下、特别是在约30℃下)实施。在这一情况下,化学处理步骤的持续时间可短于在室温下的持续时间。在化学处理的温度为约30℃的情况下,为获得小于或等于100nm的层,这一步骤持续10分钟至3小时、优选10分钟至2小时。
在本发明的又一实施方式中,化学处理步骤在冷却条件下(即,在低于室温的温度下、特别是在约10℃下)实施。在化学处理的温度为约10℃的情况下,为获得小于或等于100nm的层,这一步骤持续2-8小时、优选2-6小时。
特别是,通过将纤维浸入本发明所述的水性酸溶液中至清除二氧化硅表层并形成微孔碳层所需的时间,实施本发明所述的化学处理。优选本发明所述的水性酸溶液仅含有水和酸(HF和HNO3)。在该处理后,本发明所述的方法可包括用水漂洗、以及将所获得的经处理的纤维进行干燥的步骤。这使得能够移除本发明所述方法中使用的酸溶液的所有残留痕迹。
有利的是,随着本发明所述的处理而获得的碳化硅纤维具有≤100nm、优选约50nm的微孔碳表层。甚至更优选的是,存在于未经处理的纤维上的二氧化硅表层消失。事实上,在处理之前,纤维由二氧化硅以可变厚度覆盖,平均厚度约等于0.3微米。依靠本发明所述的处理,该层完全消失。
通过本发明所述方法处理的纤维可具有任意形式,例如纱线(yarns)、粗纱(roves)、绳股(strands)、缆索(cables)、织物(fabrics)、毡、编织物(braids)、垫、以及甚至是二维或三维的预制品。特别是可从NipponCarbon Co.公司商购的纤维。还可以是来自UBE Industries的纤维。
在本发明另外的实施方式中,待处理的纤维覆盖有不能通过化学处理移除的浆料(sizing),并且本发明所述的方法包括实质上完全移除所述浆料(优选通过热处理)的在先步骤。这是因为,虽然本发明所述的水性酸溶液引起基于聚乙烯醇的浆料部分溶解,但是其对于还可能覆盖特定碳化硅纤维的乙酸乙烯酯浆料不起作用。在后一种情况下,为了能够使得用本发明所述的水性酸溶液进行的后续处理完全有效,由此优选预先移除乙酸乙烯酯浆料。为进行这一移除,可使SiC纤维接受热退浆处理(还可使用化学退浆,热退浆处理技术比起化学退浆更有效)。例如,将SiC纤维置于温度为600℃的空气中20秒。使用相对温和的温度进行非常短的时间避免了碳化硅的任何显著的氧化。
优选待通过本发明所述方法处理的纤维在其表面上未显示出用于生产所述纤维的初始物质(例如,二氧化硅颗粒)的任何残留。
在本发明的另一实施方式中,本发明所述的方法包括将热解碳层沉积在通过本发明所述方法处理的碳化硅纤维上的额外步骤。该沉积可通过本领域技术人员公知的技术来实施,例如,专利申请FR 2567874中描述的技术。因此,该沉积直接在微孔碳层上进行。
本发明还涉及生产纤维预制品的方法,所述方法包括形成基于碳化硅纤维的纤维结构,所述纤维已根据本发明所述的处理方法进行处理。
可通过缠绕、编织、堆叠、以及任选地对二维织物层或含碳化硅纤维的缆索股进行缝织等,形成预制品。
在第一优选实施方式中,在形成纤维结构前,对纤维进行处理。因此,在对本发明所述的纤维进行处理后,将所述纤维用于生产由复合材料制成的部件的纤维预制品。
在第二优选实施方式中,在形成纤维结构后,对纤维进行处理。
因此,例如在后一情况下,直接将纤维结构浸入含有本发明所述的水性酸溶液的浴中。
最后,本发明涉及生产由复合材料制成的部件的方法,所述方法包括根据本发明所述的方法生产纤维预制品,并将所述预制品密实化。
生产由用碳化硅纤维增强的复合材料制成的部件是众所周知的。通常包括:生产陶瓷纤维预制品(其形态与待生产的部件的形态相近),以及使用基质将预制品密实化。纤维预制品构成了部件的增强物,纤维预制品的作用对机械性能而言至关重要。
可通过液态过程(用基质的前体树脂浸渍,并通过交联和热解进行转化,可重复该过程)或通过气态过程(基质的化学气相渗透)来进行纤维增强物的密实化。本发明尤其适用于生产由包含基质的复合材料制成的部件,所述基质至少部分为陶瓷、优选包含完全陶瓷的基质(CMCs),所述复合材料通过由碳化硅纤维制成的纤维增强物形成,所述纤维增强物通过基质进行密实化,所述基质为至少部分陶瓷或完全陶瓷(特别是为碳化物、氮化物、耐火氧化物等)。此类包含碳化硅纤维的CMC材料的一般实例为SiC-SiC材料(碳化硅纤维增强物和碳化硅基质)。
根据如下的附图和实施例将更加清楚地理解本发明。
