Abstract
本发明涉及一种用于制造芯复合部件(1,20,26)的方法,该芯复合部件具有在两侧带有覆盖层(3,4,22,23,27,28)的折叠型蜂窝芯(2,21,29),其中该折叠型蜂窝芯具有平行于覆盖层(3,4,22,23,27,28)延伸的有排水能力的通道(5)。首先将芯填料(16,17)至少局部地引入折叠型蜂窝芯(2,21,29)中,以便为折叠型蜂窝芯提供用于后续缝纫过程的足够的稳定性。随后将仍未利用可硬化的塑料材料浸渍的覆盖层(3,4,22,23,27,28)放置在折叠型蜂窝芯(2,21,29)上并且沿着基线(6至8)和/或顶点线(9,10)至少逐段地借助于缝纫用线(19)与该折叠型蜂窝芯缝合。然后利用可硬化的塑料材料实现整个构造的浸透和在应用压力和/或温度情况下的硬化。在方法的最后,将芯填料(16,17)通过溶解和冲洗或熔化又完全地从折叠型蜂窝芯(2,21,29)中移除。

技术领域
本发明涉及一种方法,用于制造具有在两侧带有覆盖层的折叠型蜂窝芯的芯复合部件,其中折叠型蜂窝芯具有多个平行于覆盖层延伸的有排水能力的通道。
背景技术
以夹层构造方式或作为芯复合部件构成的部件在同时重量非常小时具有非常高的机械强度。因此夹层板例如用于旅客舱的内隔板或用作为在客机中的地板支架上的底板。夹层板例如设计带有蜂窝状的芯,覆盖层安装在芯两侧上。然而特别因为由于蜂窝的封闭细胞状结构而未提供的排水能力,设计带有蜂窝状芯的夹层部件不适合用于大规格部件。可以通过应用所谓的折叠型蜂窝芯实现补偿,折叠型蜂窝芯具有多个并排平行延伸的、贯通的通道,并且因此又能够将渗透到折叠型蜂窝芯中的或在其中生成的冷凝水向外排出。
问题是夹层部件较小的损失公差,然而其与夹层部件的两种变化方案有关。对此这种危险理解为,即覆盖层在确定的芯结构的负荷状态中能至少局部地分离,并且此外这种分层过程在此在持续不断的负荷中显示出的倾向是持续进一步发展。通过这种分层使芯复合部件的结构强度突然变差,这通常立即导致涉及的部件失灵。最后提到的情况对此是决定性的原因,即现在不在大型飞机的主要结构中的值得注意的范围中考虑带有折叠型蜂窝芯的、在机械性能方面理想的夹层部件(其中在此特别需要指出良好的强度-重量-比)。
发明内容
因此本发明的目的在于,提出一种方法,用于制造带有有排水能力的折叠型蜂窝芯的芯复合部件,在该方法中特别排除了覆盖层的进一步发展的分离。
该目的根据本发明通过具有权利要求1所述的特征部分的方法以及根据权利要求12通过带有两侧带有覆盖层的折叠型蜂窝芯的芯复合部件而实现。优选的实施方案是各个从属权利要求的内容。
根据本发明的方法具有下列的步骤:
a)将芯填料至少局部地引入至少一个折叠型蜂窝芯中;
b)在折叠型蜂窝芯上布置下部的和上部的干燥的覆盖层;
c)至少局部地将覆盖层机械地连接在折叠型蜂窝芯处;
d)利用可硬化的塑料材料浸渍覆盖层;
e)在应用压力和/或温度的情况下使整个芯复合部件硬化;和
f)移除芯填料。
由于在方法步骤c)中实现将两个覆盖层机械地连接在折叠型蜂窝芯处,特别在飞机的所有出现的工作状态下可靠地排除了覆盖层的局部进一步发展的分层。所以借助于根据本发明的方法制造的带有折叠型蜂窝芯的芯复合部件首次不受限制地适合应用在飞机的主要结构中。
在根据本发明的方法步骤中首先在步骤a)中将芯填料至少局部地引入到稍后的芯复合部件的至少一个折叠型蜂窝芯中。为了稍后实现将覆盖层机械连接在芯结构处,引入芯填料用于折叠型蜂窝芯的机械的稳定。芯填料是可硬化的材料,在制造芯复合部件之后通过合适的溶剂或温度的应用又可以无残渣地从其中移除该材料。材料“AquaCore”例如可以作为芯填料使用,该材料在水中可溶并且因此可无残渣地从芯复合部件的内部中冲洗出。可替换地,低熔点的蜡或金属合金也可用作芯填料。
在随后的方法步骤b)中,将下部的和上部的分别“干燥的”覆盖层放置在折叠型蜂窝芯上。覆盖层设计带有已知的增强纤维布置、例如碳纤维织物或碳纤维无卷曲材料,其中术语“干燥”指的是还未实现的、利用可硬化的塑料材料,例如环氧树脂、聚酯树脂、酚醛树脂或BMI-树脂的浸渍。与此相反,折叠型蜂窝芯设计带有已经利用经硬化的塑料材料浸渍的增强纤维布置。用于折叠型蜂窝芯的合适的材料例如是所谓的Nomex纸张或利用环氧树脂浸渍的并且随后硬化的碳纤维增强布置。
此外在这个阶段中实现匹配于要制造的芯复合部件的预定的额定几何形状。
在方法步骤c)中实现将覆盖层机械地连接在折叠型蜂窝芯处。因此与迄今为止通常的、纯粹带粘性的连接相比较,相对于折叠型蜂窝芯的覆盖层的局部进一步发展的分层获得基本上更高的安全性。因此根据本发明制造的芯复合部件具有高的损失公差,该损失公差也允许无问题地使用在大型客机的主要结构中。附加地可以至少逐段地设计为将折叠型蜂窝芯与两个覆盖层中的至少一层附加地粘合。下部的和上部的覆盖层的机械连接可以同时或相继实现。
在随后的方法步骤d)中利用合适的可硬化的塑料材料浸渍两个覆盖层。为了在避免空气夹杂和其它不期望的成穴的情况下实现尽可能完整和均匀的浸渍两个覆盖层,必需的是,至少局部地利用薄膜覆盖整个构造和通过提供施加真空来加强该浸渍过程。
在接着的方法步骤e)中,在应用压力和/或温度的情况下实现制成的芯复合部件的硬化,其中该过程步骤例如在炉子中或在压煮器中实现。
在最后的方法步骤f)中将芯填料从芯复合部件中移除。将芯填料无残渣地移除可以取决于具体使用的材料例如通过冲洗出或熔化出来实现。
在本方法的一个有利的改进方案中借助于至少一个合适的工具在机械连接覆盖层之前为芯复合部件提供不同于平坦的形状的几何形状。由此例如单次(圆柱形的)或两次(球形的)弯曲的壳形区段根据本方法可用于制造飞机的机身部段。机身部段通过多个这种壳形区段在圆周方面的接合分别在产生纵缝的情况下制造。在此优选使用至少四个壳形区段。
根据本方法的另一个改进方案,实现将覆盖层通过缝合机械地连接在折叠型蜂窝芯处。由此以简单的方式获得在覆盖层和折叠型蜂窝芯之间的牢固的机械连接。表面覆盖的缝合通常不是必需的。为了安全地阻止至少局部进一步发展的分层,通常至少局部的缝合是足够的。作为“缝纫用线”优选使用的是由同样材料构成的粗纱,其也应用于覆盖层。对于这种情况,即覆盖层例如由碳纤维织物或碳纤维无卷曲材料构成,作为缝纫用线以有利的方式应用至少一种碳纤维粗纱或碳纤维条。然而原则上每种足够抗拉的塑料纤维或每种塑料纱线或每种天然纤维都可应用作为缝纫用线。例如作为缝纫用线可用的是碳纤维粗纱、聚酯线、芳香族聚酰胺-线或大麻线。因为缝纫用线穿过覆盖层和折叠型蜂窝芯,所以通过利用可硬化的塑料材料最终浸渍覆盖层,确保缝纫用线在其各自的位置中。
根据本方法的另一个优选的实施方式,至少一个覆盖层至少局部地与折叠型蜂窝芯粘合。因此可以实现相对于分层的附加的安全性。此外改善了缝纫用线的位置固定。
根据本方法的一个改进方案,基本上沿着折叠型蜂窝芯的基线和/或顶点线实现缝合和/或粘合。由此使得用于缝合的缝纫头更容易定位。缝纫头的位置控制例如可以通过在顶点线和/或基线的区域中升高的电导率实现。这种局部的电导率升高可以例如通过利用可溶性的导电膏的涂覆而起作用,在树脂浸渍过程之前无残渣地移除导电膏,并且导电膏能够例如沿着折叠型蜂窝芯的基线和顶点线感应引导缝纫头。可替换地,通道的取向也可存放在CNC-控制中,然后借助于CNC-控制对缝纫头进行计算机控制的引导。
折叠型蜂窝芯的贯通的、有排水能力的通道在缝纫过程的实施期间至少局部地利用芯填料填充,以用于机械稳定。可在空间中自由定位的缝纫头用于引导针和缝纫用线。作为针优选应用的是圆形针,以便可以从芯复合部件的一侧实施缝纫过程。借助于针,例如实现在顶点线或基线的区域中和至少一个覆盖层的区域中穿透折叠型蜂窝芯。通过将缝纫用线自身通过环结构附加地打结可以进一步提高缝的强度。原则上两个覆盖层可在缝纫过程中连接在折叠型蜂窝芯处。可替换地,首先实现上部的覆盖层的缝合并且在翻转芯复合部件后实现将下部的覆盖层和折叠型蜂窝芯缝合。在一定条件下可能需要的是,在用于对覆盖层和/或折叠型蜂窝芯的位置进行固定的缝合过程之前设置互相涉及的附加的固定工具(针、粘合点、粘合带等)。
在本方法的一个改进方案中,折叠型蜂窝芯在基线和/或顶点线的区域中具有至少逐段的法兰,其中将法兰和覆盖层缝合。由此在折叠型蜂窝芯和覆盖层之间实现更大的连接面和因此实现更高的负荷能力。此外借助于优选布置在两侧的法兰可能的是,缝可以在顶点线和/或基线的两个侧面上延伸。法兰优选地通过在两侧的“折弯”构成一个整体,并且在两侧水平于折叠型蜂窝芯的顶点线或基线,分别平行于下部的或上部的覆盖层延伸。为了阻止褶皱,必需的是,法兰在具有梯形、蜿蜒曲折形或正弦形的顶点线和基线或贯通的通道的折叠型蜂窝芯的情况下逐段地带有多个互相均匀间隔的凹口。凹口可在蜿蜒曲折形或梯形的通道的情况下特别在基线和顶点线的转折点的区域中(所涉及的线的方向改变)引入到法兰中。
在本方法的一个改进方案中为芯复合部件提供基本上为壳形区段形状的几何形状。
然后完整的机身部段通过接合多个(特别是至少四个)这样的壳形区段在形成在纵向方向上延伸的纵缝的情况下完成。
根据另一个有利的实施方式为芯复合部件提供基本上为空心圆柱形的几何形状。由此可能的是,完整的机身部段以集成的构造方式利用根据本发明的、具有折叠型蜂窝芯的芯复合部件进行制造,从而可以不可替换地取消了重量增加的纵缝,该纵缝在接合由多个壳形区段组成的机身部段时产生。
根据本发明的芯复合部件包括在两侧带有覆盖层的折叠型蜂窝芯,该折叠型蜂窝芯具有平行于覆盖层延伸的有排水能力的通道。
由这种方法,即在顶点线和/或基线的区域中的覆盖层至少逐段地与折叠型蜂窝芯机械连接、特别是缝合,由此得出设计利用根据本发明的芯复合部件构成的部件的高的损失公差。特别地,避免折叠型蜂窝芯的覆盖层的进一步发展的分离,因而芯复合部件不受限制地适用于大型飞机的主要结构的内部。

具体实施方式
图1在透视图中示出利用根据本发明的方法缝合的芯复合部件构成的壳形区段,用于制造飞机机身部段。
此外芯复合部件1设计带有折叠型蜂窝芯2,在折叠型蜂窝芯上涂覆了下部的和上部的覆盖层3,4。折叠型蜂窝芯2具有多个贯通的、有排水能力的通道,它们分别相应于蜿蜒曲折形延伸的通道5设计。折叠型蜂窝芯2朝下通过三条基线6至8限定,而两条顶点线9,10朝上限定了折叠型蜂窝芯2。不仅基线6至8而且顶点线9,10都以蜿蜒曲折形的重复单位延伸,但也可以例如梯形、近似矩形或正弦形延伸。折叠型蜂窝芯2在所有图示方向上继续前进。芯复合部件1在图1的实施例中具有近似单次弯曲的(空心圆柱形)空间结构,然而也可以两次的(球形的)弯曲地设计或设计为平板。
覆盖层3,4例如利用碳纤维织物或碳纤维无卷曲材料构成并且利用环氧树脂渗透。折叠型蜂窝芯2优选地利用Nomex纸张构成,然而例如也可以利用任意的碳纤维增强布置(织物,无卷曲材料)制造,该碳纤维增强布置利用可硬化的热固性塑料材料,如环氧树脂、聚酯树脂、酚醛树脂或BMI-树脂浸渍。通过根据本发明的方法,两个覆盖层3,4沿着基线6至8或顶点线9,10和折叠型蜂窝芯、如通过虚线表示那样缝合。折叠型蜂窝芯2分别沿着基线和顶点线6至10相对指向地折叠,用于实现所示出的空间结构。由此形成的三个基缝11至13和两个顶点缝14和15在基线或顶点线6至10的区域中。优选地应将相同的材料用于缝纫用线,该材料也用作在覆盖层3,4和折叠型蜂窝芯2内部的增强纤维。由此实现在覆盖层3,4的树脂基体中的缝纫用线的良好的固定。
由于将覆盖层3,4和折叠型蜂窝芯2缝合,几乎排除了覆盖层3,4与折叠型蜂窝芯2之间的进一步发展的分层(如该分层可能在纯粹的粘合连接时出现的那样)。基线6至8和顶点线9,10不需要贯通地和折叠型蜂窝芯2缝合。通常地,例如以在芯复合部件1的整个平面上10cm的均匀的正方形的格栅距离中的逐点的缝合足以安全地应对覆盖层3,4与折叠型蜂窝芯2之间的局部分离的危险。由此可以无需附加措施地使用芯复合部件1作为结构部件、例如作为壳形区段,用于构成大型飞机的机身部段。
根据图2更清楚地说明本方法的流程,该视图示出了穿过根据图1的加长示出的芯复合部件的示意性横截面,该芯复合部件带有已经部分引入的芯填料。
首先在第一方法步骤a)中,将芯填料16,17引入到折叠型蜂窝芯2的通道中。芯填料16,17是硬化的材料,在芯复合部件1制成后又可从其中无残渣地移除该材料。材料AquaCore例如可以用作芯填料16,17,通过作为溶剂的常用的水又可以将该材料从折叠型蜂窝芯2中冲洗出。因此在芯复合部件中丝毫没有残留增加重量的组成成分。
在随后的方法步骤b)中,将最初仍“干燥的”下部的和上部的覆盖层3,4定位在折叠型蜂窝芯2上,也就是说还没有缝合。“干燥”的概念在上下文中意味着的是,覆盖层3,4的增强纤维布置还没有利用可硬化的塑料材料浸透,覆盖层例如是碳纤维织物或碳纤维无卷曲材料。在这个方法阶段中可以(只要芯填料16,17还没有完全硬化)为需要制造的芯复合部件1提供不同于所示出的平坦的形状的、预定的额定几何形状,折叠型蜂窝芯2的空间形状已在制造厂商方面再次匹配于该额定几何形状。这例如可以通过相应成型的支座和/或相应于额定几何形状的压板发生,用于成型或机械支持折叠型蜂窝芯结构2。通过芯填料16,17确保的是,通过随后将覆盖层3,4机械连接在折叠型蜂窝芯2处的过程不能使折叠型蜂窝芯2实现未限定的变形。
当芯填料16,17在折叠型蜂窝芯中完全硬化之后,在方法步骤c)中至少局部地实现将覆盖层3,4机械地连接在折叠型蜂窝芯2处,这种连接优选地通过所列举的部件的传统的缝合实现。例如通过未示出的、可在空间中自由定位的缝纫头实现缝合,该缝纫头带有至少一个用于容纳合适的缝纫用线的圆形针。折叠型蜂窝芯2优选地在顶点线9,10以及基线6至8(如通过垂直的、点划线所示出的基缝或顶点缝11至15表明)的区域中与两个覆盖层3,4缝合。由此足够的是,只是在折叠型蜂窝芯2和覆盖层3,4之间进行局部缝合。
在将折叠型蜂窝芯2与两个覆盖层3,4缝合结束之后,在方法步骤d)中实现利用可硬化的塑料材料、例如环氧树脂,在应用真空的情况下借助于通常的树脂浸渍过程对芯复合部件1进行浸渍。在此缝纫用线同时一起被浸透,因此实现了在覆盖层3,4和折叠型蜂窝芯2之间的、可在机械方面极端负荷的连接。因此特别也在飞机运行中的极端的负荷条件下排除覆盖层3,4与折叠型蜂窝芯2之间的进一步发展的分层。芯复合部件1的树脂浸渍例如可在应用用于覆盖的薄膜的情况下实现,对该薄膜施加足够的负压以用于使渗透过程加速和均匀化。
随后在方法步骤e)中在同时应用压力和/或温度的情况下可以实现整个构造的硬化,这例如可在通常的炉子或在压煮器中完成。
为了制成芯复合部件1,在最后的方法步骤f)中将芯填料16,17从折叠型蜂窝芯2的所有的空腔或通道中移除。对于这种情况,即蜡状的物质或低熔点的金属合金用作为芯填料16,17,则芯填料16,17的移除也可以通过加热实现,并且通过重力作用实现自动地向外流出。为了通过离心力的作用使该过程加速,芯复合部件也可以转入快速的旋转中。
图3示出利用圆形针的缝纫过程的原则性的流程。
圆形针18可摆动地铰接在未示出的缝纫头上。圆形针18用于引导缝纫用线19并且穿过芯复合部件。圆形针18可借助于多个未示出的促动器定位在空间中的至少六个轴中,其中促动器由控制装置和调节装置进行操纵。由此圆形针18可以类似于在一侧的手工缝纫过程实现运动。
芯复合部件20包括在两侧带有互相平行延伸的覆盖层22,23的折叠型蜂窝芯21(参见图1,2)。为了实施缝纫过程,折叠型蜂窝芯21优选地完全利用用于稳定性的合适的芯填料进行灌注,为了更好的显示的概括性而未示出芯填料。芯复合部件20放在优选为金属的、实心的(成型)工具24上,以便为芯复合部件20提供限定的几何形状。工具24(其在示出的实施例中具有平坦的几何形状)也可以可替换地一维或二维(球形的)弯曲设计。在通过芯填料至少局部地填满的折叠型蜂窝芯的固有刚性足够时不需要工具。
在圆形针18和缝纫用线19分别在两个穿透位置处穿透上部的覆盖层23以及折叠型蜂窝芯21(如通过小椭圆或圆表示的那样)并且由上部的覆盖层23完全地穿出之后,圆形针18借助于合适的支撑在缝纫头处“转动”并且相应地穿透上部的覆盖层23以及折叠型蜂窝芯21,仅仅在相反的方向上,在形成四个其他的、同样通过椭圆示出的、在折叠型蜂窝芯21中和在上部的覆盖层23中的穿透位置的情况下,直至圆形针18又完全从芯复合部件20穿出。在此在覆盖层23上方构成回线25,通过该回线引导缝纫用线19并且最后借助于针18拉紧。在覆盖层22,23浸渍前,在需要的情况下通过缝纫用线19的带粘性的涂层改善产生的缝的耐久性。缝纫用线19的、穿过芯复合部件20的穿透方向由两个在缝纫用线19的终端方面的方向箭头示出。
这种回线构成过程这样周期性地重复,直至缝合沿着折叠型蜂窝芯21的顶点线完全地闭合,其中沿着预定的轨迹引导缝纫头。缝纫过程至少逐段地在其余的顶点线处继续。在这种缝纫方法中只可以在芯复合部件在工具24上翻转后实现将折叠型蜂窝芯21的基线与下部的覆盖层22缝合。上述示范性示出的缝纫过程只是多个可替换的缝合形成方式中的一种可能的方式。
代替圆形针18也可使用传统的直针。在这种情况下,相继穿透两个覆盖层22,23,其中缝纫用线19分别近似垂直地在覆盖层22,23之间延伸并且在顶点线和基线之间的区域中、也就是在折叠型蜂窝芯21的倾斜竖立的侧面的区域中一次穿透折叠型蜂窝芯21。最后,折叠型蜂窝芯21可以在顶点线以及基线的区域中附加地至少逐段地与覆盖层22,23粘合。在这种方法变体中,在支撑的工具和芯复合部件20之间,在芯复合部件20下方布置了利用弹性体构成的中间层(橡胶垫),以便阻止也穿透下部的覆盖层22的针穿过位于其下面的工具24的损害。
在图4中示出将带有法兰的折叠型蜂窝芯缝在芯复合部件的覆盖层处的可替换的实施变体。
芯复合部件26包括两个覆盖层27,28,它们在两侧覆盖折叠型蜂窝芯29。与前述的折叠型蜂窝芯不同的是,折叠型蜂窝芯29分别地在基线30以及顶点线31的区域中具有向两侧水平均匀伸展的法兰32。法兰32在折叠型蜂窝芯29的制造过程期间通过重复的折叠产生。通过法兰32放大了在覆盖层27,28和折叠型蜂窝芯29之间提供的接合面或者说连接面,这特别有利于附加地实现粘合和/或缝合。
此外,法兰32使在基线30或顶点线31的两侧上可以实现缝合,如通过垂直延伸的点划线所表示的那样,由此进一步改善了根据本发明通过缝合实现的、在折叠型蜂窝芯29和覆盖层27,28之间的连接的机械负荷能力。
