Description
技术领域
本发明涉及用于放置旨在用于制造复合材料部件的形状填充的粗纱的设施的一般领域。本发明还涉及一种使用这种设施制造复合材料部件的方法。
背景技术
已知通过以预浸渍的纤维增强层的形式覆盖来生产复合材料部件。在一些当前技术中,覆盖由操作人员手动进行。这些技术会导致相对较高的部件生产成本,并且会导致层定位错误的风险。这导致获得的部件的机械性能中的某些变化,并导致其机械性能可以改善的部件。
已经开发了其它解决方案,比如自动纤维放置(AFP)。这种机械化技术对于降低复合材料的部件的生产成本有益处。在现有技术中,将纤维层覆盖在表面上以获得所要获得的部件的预成型件,然后将包含陶瓷或碳颗粒的砂浆注入覆盖的预成型件的孔隙中,最后烧结颗粒以形成基质。尽管有效,这种方法的时间和成本可以进一步减少。
发明内容
为此,根据第一方面,本发明提供一种用于沉积成形的填充的粗砂的装置,该粗纱旨在用于制造复合材料部件,该装置至少包括:
用于馈送浸渍有包括粘合剂和陶瓷或碳填料的组合物的纤维粗纱的设备,
由至少一个多孔表面限定的用于成形和排出粘合剂的模具,该模具在入口截面和出口截面之间具有逐渐演变的截面,入口截面大于出口截面,
与模具的出口连通的支承件,成形的粗纱将沉积在该支承件上,以及
第一输送设备,该第一输送设备构造成将来自馈送设备的粗纱运送通过模具并到达支承件。
“粗纱”是指基本上彼此平行行进并连结在一起以形成非织造网状物的一组纤维或长丝。入口或出口横截面是由喷丝头的入口或出口开口限定的区域。
通过这种装置,可以制造成形的填充的粗纱,即,其浸渍有包括粘合剂和填料的组合物并且具有预定的尺寸,其可以用于使用AFP技术的制造方法中。根据本发明的装置的粘合剂成形和排出的模具因此使得能够将粗纱压延至预定尺寸,同时消除粘合剂的一部分并将填料捕获在粗纱中,以便在粗纱中获得较高填料比率。通过排出部分粘合剂来减少由粗纱所占据的体积,从而提高填料比率,但通过多孔表面的过滤又不允许填料逸出。
借助这种装置,通过充分增加粗纱中的填料的速率,不再需要执行砂浆(barbotine)注射步骤,或更一般地将附加填料引入沉积的粗纱的孔隙中以形成预成型件。换言之,通过增加如装置允许的粗纱中的填料的比率,并通过使用可移除的粘合剂(例如在热的作用下),能够直接烧结包括离开装置的粗纱的覆盖物的预成型件,并获得期望的孔隙率,而无需首先执行将填料引入预成型件的步骤。
通常,应当选择多孔表面的孔隙尺寸以确保粘合剂排出,同时将填料捕获在粗纱中。多孔表面的孔隙尺寸可以严格小于填料的尺寸。在一个示例中,孔隙的孔隙尺寸D90可以严格小于填料尺寸D10。例如,孔隙尺寸D90可以小于或等于10μm,或小于或等于5μm,或小于或等于0.3μm。注意到,多孔表面的孔隙尺寸不一定必须小于填料的尺寸。实际上,填料通常部分地阻挡比填料的尺寸更大的孔隙,从而减小了有效孔隙尺寸并且仍然提供过滤功能。
在示例实施例中,多孔表面的材料可以是具有开放孔隙率的多孔材料,以确保粘合剂的排出。多孔材料可以是多微孔的或纳米多孔的,例如纳米多孔的陶瓷材料,其可以通过部分烧结陶瓷粉末、陶瓷或金属泡沫而获得,或者多微孔的有机材料。
在示例实施例中,该装置还可以包括第二输送设备,该第二输送设备构造成在粗纱和多孔表面之间循环多孔膜,该多孔膜所具有的孔隙尺寸严格大于填料的尺寸。该膜促进将粗纱输送通过模具,同时可渗透组合物。例如,多孔膜的孔隙尺寸D50可以是填料的尺寸D50的至少两倍。
在示例性实施例中,该装置还可以包括与多孔表面连通的泵送设备。例如,泵送设备可包括连接到每个多孔表面的泵。当仅通过模具输送粗纱不够有效时,泵送设备的存在可以改善粘结剂的排出。
在示例实施例中,该装置包括用于模具的加热设备。该设备加热穿过模具的粗纱。因此,它能够调节粘合剂的粘度,例如使其软化或液化,以促进排出。
在示例实施例中,该装置还可以包括分配头,该分配头与模具的出口连通,并且构造成将成形的粗纱沉积在基材上。
在示例实施例中,分配头可以是用于自动纤维放置的分配头,即,用于实施AFP技术。为了简洁起见,在下文中将自动纤维放置技术称为“AFP技术”。
在示例实施例中,支承件可以构成成形的粗纱的存储辊。在一些情况下,有利的是,该装置另外包括与存储辊连通的塑料膜馈送设备,以便通过塑料膜分开缠绕在存储辊上的粗纱的各层并允许它们随后分开以使粗纱更容易解绕。
在示例实施例中,多孔表面可以在横向于输送粗纱通过模具的方向的方向上移动。这种有利的布置允许多孔表面在模具中压实粗纱,以改善粘合剂的排出。
在示例实施例中,模具可包括面向彼此的两个多孔表面。
最后,根据第二方面,本发明涉及一种制造复合材料部件的方法,该方法至少包括:
-形成纤维预成型件,该纤维预成型件包括来自使用上述装置形成的一根或多根粗纱的陶瓷或碳填料,以及
-从陶瓷或碳填料在纤维预制品的孔隙中形成基质。
在示例实施例中,可以通过烧结填料形成基质。在烧结步骤期间,可以移除粘合剂,因此形成逃逸性粘合剂。通过这种布置,可以在单个烧结热处理步骤中获得基质。
在示例实施例中,粗纱可以在其成形期间逐步地前进通过模具。有利地,多孔表面可在相对于在模具中输送粗纱的方向的横向方向上移动,以压实粗纱并在两个连续的前进之间排出粘合剂。
附图说明
参考示出了非限制性示例实施例的附图,本发明的其它特征和优点将从下面给出的描述中变得明显。在附图中:
-图1是示出根据本发明的实施例的装置的示意性剖视图,
-图2是示出了可用于放置粗纱以通过AFP技术形成纤维结构的分配头的示意性剖视图,以及
-图3是示出根据本发明的制造复合材料部件的方法的各种步骤的流程图。
具体实施方式
图1示出了根据本发明的实施例的装置1。装置1旨在用于放置填充和成形的粗纱2,粗纱2本身旨在用于制造复合材料部件。在此处示出的示例中,粗纱2在箭头4所示的方向上在装置1中移动,该方向对应于输送方向。
装置1在输送粗纱2的方向上从上游到下游包括:馈送设备10,其用于浸渍有包含粘合剂和陶瓷或碳填料的组合物的纤维粗纱;模具20,其用于成形和排出由馈送设备10馈送的粘合剂;以及辊子30,其构成与模具20的出口连通的支承件。
馈送设备10在此包括辊子11,仍然干燥的粗纱2可以存储在辊子11上。成对反向旋转的辊子12构造成在浸渍之前将粗纱2驱动至预定的尺寸。在所示的示例中,馈送设备10还包括箱体13,箱体13具有入口开口14和出口开口15,干燥的粗纱2通过该入口开口14进入箱体,浸渍的粗纱2通过出口开口15出来。箱体13包含包括粘合剂和陶瓷或碳填料的组合物16。箱体13还可以包括用于均化组合物16的器具(未示出),例如搅拌设备。在箱体13内部,粗纱浸入用于浸渍的组合物16中。当然可以设想其它浸渍粗纱的手段。为了使组合物更好地浸渍在组成它的细丝内部,干粗纱2可以在进入箱体13之前被拉伸并且至少部分地被去致密化。
包括粘合剂和陶瓷或碳填料的组合物可以包含按体积计大于20%的陶瓷或碳填料,较佳地按体积计大于30%。
馈送设备10可以构造成使得在浸渍粗纱2之前,后者的尺寸大于粗纱2在模具的出口处将具有的尺寸(最终尺寸)。例如,当粗纱2具有矩形截面时,其在馈送设备10中的宽度可以在其最终宽度的110%至120%之间,并且其厚度e1可以在其最终厚度e2的110%至160%之间。可以确保粗纱2在进入箱体13时充分通风,从而使浸渍更加有效。
可以考虑各种材料构成粗纱2的纤维。特别地,它可以由陶瓷或碳纤维制成。陶瓷纤维可以是诸如碳化硅SiC之类的非氧化物材料的纤维,或者是诸如氧化铝、玻璃(玻璃纤维)或莫来石之类的氧化物材料的纤维。在示例性实施例中,所使用的纤维可以是由日本公司日本碳(Nippon Carbon)以“Nicalon”、“Hi-Nicalon”或“Hi-Nicalon-S”的名称供应的或由公司宇部兴产(UBE)以“暴龙-SA3(Tyranno-SA3)”的名称供应的SiC纤维。也可以使用3M公司以“Nextel”的名称供应的氧化铝纤维。由东丽(Toray)公司以托来佳T300(ToraycaT300)的名称提供的纤维是可用的碳纤维的示例。粗纱还可以包括诸如芳族聚酰胺纤维(凯芙拉)之类的聚合物纤维、硼纤维或碳纤维或这些纤维的混合物。纤维的粗纱可以被滴定至至少5000但尼尔(deniers),较佳地在10000至50000但尼尔之间。
陶瓷填料可以例如包括选自以下的材料:SiC、Al2O3、SiO2、(3Al2O3,2SiO2)、TiO2、ZrO2或这些材料的混合物。陶瓷或碳填料所具有的尺寸D50可较佳小于或等于5μm,或更较佳小于或等于2μm,或者甚至更较佳小于或等于1μm。例如,陶瓷或碳填料所具有的尺寸D50可以在0.3μm和1μm之间。陶瓷或碳填料的尺寸D10可以小于或等于0.3μm。
通常,粘合剂可以是有机粘合剂。粘合剂可以包括沥青、焦油或天然树脂。粘合剂可以是选自以下的热塑性类型的一维聚合物:碳酸亚烷基酯(polyalkylene carbonates)、特别是聚碳酸亚丙酯和聚碳酸亚乙脂、脂肪族共聚酯、比如聚丁二酸丁二醇酯(PBS)、半芳族共聚酯、比如聚对苯二甲酸乙二醇酯(PET)和聚对苯二甲酸丁二醇酯(PBT)、聚甲基丙烯酸甲酯(PMMA)、聚乙烯醇(PVA)及其混合物。粘合剂可以是两组分的(热固性)有机粘合剂,例如包含来自环氧族的树脂。粘合剂可以例如具有在10000和50000之间的平均分子量。
模具20在此呈块的形式,在其内部是在模具的入口22和出口23之间水平延伸的通道21。模具20构造成使得粗纱2存在于通道21中。在该示例中,通道21具有逐渐演变的矩形截面。特别地,其在入口22处的截面大于其在出口23处的截面。这样,模具20将粗纱2的厚度修改为从厚度e1到最终厚度e2。模具20的通道21在侧部上一方面由竖直表面(在图1中不可见)界限,另一方面由多孔表面24竖直地界限。在所示的示例中,多孔表面是平坦的,并且相对于水平面倾斜。在该示例中,粗纱2的厚度相对于其宽度减小,并且多孔表面24因此具有比竖直表面大的表面积。
多孔表面24可以是多孔材料块25的表面,该多孔材料块25比如是多微孔或纳米多孔材料,例如宝利是通过部分烧结陶瓷粉末获得的微孔陶瓷材料块、陶瓷或金属泡沫块、或者多微孔有机材料。每个多孔表面可具有大于或等于10%,例如在10%至40%之间的体积孔隙率(开口孔隙率)。多孔材料25的孔隙尺寸可以选择为严格小于陶瓷或碳填料的尺寸,例如,孔隙尺寸D90严格小于陶瓷或碳填料的尺寸D10。作为通用规则,应注意确保多孔材料25的孔隙尺寸允许填料集中在粗纱2中,防止其逸出,同时允许从粗纱2有效地排出粘合剂。
可以简单地通过将粗纱2输送到模具中来进行排出,该输送在多孔表面24上产生压力,该压力允许移除粘合剂。然而,为了改善粘合剂的排出,特别是当粘合剂具有高粘度或粘合剂中的陶瓷或碳填料的级别较高时,使用诸如泵之类的泵送设备(图1中的箭头)可能是有利的,该泵送设备连接到模具的排出出口26。可以将加热设备(未示出)集成到模具中,例如在模具的侧腹处,以便加热粘合剂以降低其粘度并改善其通过多孔表面24的排出。排出出口26本身通过多孔材料25连接到多孔表面24。
当然,模具的通道21的截面的形状可以根据需要和粗纱2的期望形状而与所示的形状不同。此外,模具20可以仅包括两个多孔表面24,特别是当粗纱2的厚度与其宽度相比可以忽略不计时。
粗纱2在装置1内部的输送通过第一输送设备来提供,该第一输送设备包括例如用于使辊子11、辊子30和辊子12旋转的器具(未示出)。第一输送设备可构造成使得粗纱2较佳以0.01m/min至20m/min之间的速度、更较佳地以0.1至10m/min之间的速度、甚至更较佳以0.1至2m/min之间的速度移动通过模具20。特别地,输送速度将被选择为足够低,以使得馈送设备10中的浸渍被正确地执行并且模具20中的排出能够发生。应当注意,输送可以是连续的,或者替代地是半连续的。例如,在半连续的情况下,粗纱2可以逐步前进通过模具,并且多孔表面24可以彼此独立地竖直(即,在横向于粗纱2输送通过模具的方向的方向上)移动,从而在粗纱2的两个连续前进之间压缩粗纱2。
为了促进粗纱2输送到模具20中,使用第二输送设备可能是有利的,该第二输送设备包括例如成对移动的多孔膜27,成对移动的多孔膜27伴随粗纱2进入模具20中,每个多孔膜27通过位于模具20上游和下游的辊子28驱动。每个多孔膜27定位在多孔表面24和粗纱2之间,并与其接触。多孔膜27构造成能够被粘合剂和填料穿过并且具有促进粗纱2输送通过模具的作用。多孔膜27的孔隙尺寸因此可以大于浸渍到粗纱2的填料的尺寸。例如,多孔膜27的孔隙尺寸D90可以严格大于陶瓷或碳填料的尺寸D10。多孔膜27的馈送速度可以与在装置中的粗纱2的输送速度相同。在未示出的变型中,装置1没有多孔膜27,使得粗纱2与模具20的多孔表面24接触。
在所示的装置中,离开模具20的粗纱2被存储在支承件上,在此该支承件由存储辊30构成。为了防止缠绕到支承件30上的粗纱2的各层粘附在一起,并且可以更容易地解绕,可以与粗纱2同时缠绕膜片31,例如塑料膜。可以通过塑料膜供应设备来供应膜片31,该塑料膜供应设备包括例如布置在存储辊30上游的粗纱2下方的辊子32。然后可以使用存储在辊子30上的粗纱2馈送如下描述的分配头。替代地,粗纱2可直接用于馈送与模具20的出口连通的分配头。
图2示意性地示出了AFP设备的分配头40的结构。分配头40可用于上述装置1中。所示的分配头40的结构本身是已知的。分配头40由浸渍有粘合剂和陶瓷或碳填料的粗纱2馈送,以产生纤维预成型件。
纤维预成型件形成在支承件50的表面S上。为此,分配头40利用粗纱2馈送。粗纱2通过输送元件41输送到在表面S的侧部上的压力施加元件42。输送元件41呈成对反向旋转辊子41a和41b的形式,在它们之间存在粗纱2。输送元件41用于使粗纱2在由箭头F1表示的方向上向压力施加元件42前进。当分配头40与模具20的出口连通时,那么输送元件41是装置1的第一输送设备的一部分。
压力施加元件42将压力施加到粗纱2,以便将其沉积在表面S上。压力施加元件42在此为辊子的形式。另外,分配头40还可具有位于压力施加元件42附近的加热元件43。如果需要,该加热元件43使得能够在粗纱2沉积期间加热粗纱2,以使粘合剂流化并因此赋予沉积的粗纱期望的附着力。
在沉积期间,可以移动分配头40,以便将粗纱2施加到表面S的第一确定区域(箭头F2)。一旦已经施加第一区域,分配头40上的切割元件44就切割粗纱2。在该切割之后,由粗纱2的第一部段形成的第一浸渍的纤维结构沉积在表面S的第一区域上。首先,在沉积第一纤维结构之前,可以将热塑性材料的初始层沉积在表面S的第一区域上,并且可以将第一纤维结构然后沉积在该热塑性层上。该初始热塑性层的沉积是可选的。
然后通过致动输送元件41使分配头40中的粗纱2前进到压力施加元件42而继续预成型件的形成。可以移动分配头40以便将粗纱2沉积在表面S的与第一区域分离的第二区域上。然后以与上述类似的方式在表面S的第二区域上获得由粗纱2的第二部段形成的第二浸渍纤维结构的沉积。然后,通过以与上述相同的方式沉积一种或多种其它浸渍的纤维结构,继续预成型件的生产。
图3概括了实现上述装置1的复合材料部件的制造方法的步骤。复合材料部件包括由基质致密化的纤维增强件。
第一步骤100包括形成纤维预成型件,该纤维预成型件包括来自已经成形的一根或多根浸渍的粗纱的陶瓷或碳填料。纤维预成型件旨在形成部件的纤维增强件。该步骤可以在根据本发明的装置1中进行。步骤100可以分解为若干子步骤。首先,子步骤110在于利用包括粘合剂和陶瓷或碳填料的组合物浸渍粗纱2。该子步骤110在装置1的对应于馈送设备10的部分中进行,该馈送设备10尤其包括其中存在组合物的箱体16。然后,子步骤120包括使粗纱成形并排出粘合剂存在于粗纱2中的部分。该子步骤120在装置1的模具20中进行。在模具20的出口处,将粗纱成形为接近其最终尺寸的尺寸,并且粘合剂已从其中排出,以便增加粗纱2中的填料浓度。然后,在子步骤130中,将成形的填充的粗纱2沉积在支承件上。取决于装置1的构造,可以将粗纱2沉积在存储辊30上,然后使用存储辊30来馈送到例如分配头40。替代地,能够利用离开模具20的粗纱40来直接馈送分配头40。在任一情况下,然后都可以使用如上所述的分配头40使用AFP技术形成部件的纤维预成型件。除AFP以外的其它方法当然能够用于从成形的填充的粗纱2形成纤维预成型件。
该方法的第二步骤200最终包括由其中存在的陶瓷或碳填料在纤维预成型件的孔隙中形成基质。该步骤可以简单地包括纤维预成型件的烧结热处理。然后可以通过加热去除浸渍预成型件的粘合剂,并且将预成型件内部的填料烧结以填充纤维预成型件内部的孔隙并获得最终部件。
实施根据本发明的装置来沉积成形的填充的粗纱的方法使得可以克服以下步骤,其中在基质形成之前将填料引入预成型件中,这些填料已经存在于通过沉积粗纱获得的预成型件中。根据本发明的方法因此比现有技术的方法更简单并更快速地执行。
在整个公开中,“在……与.……之间”的用语应当理解为包括界限。
