Abstract

本发明涉及一种层压层的切割方法，该层压层用在包括多个组合层压层(703)的纤维加强的层压物体(701)中，其中，至少沿着层压层的至少一个边缘的一段在层压层厚度上进行渐尖切割，从而减小层压层的厚度。由于不仅可减少层压层的数量，而且还减少了各个层压层的厚度，因此获得了可用于层压物体中的层压层，通过其可减少富含树脂区域和气穴的问题以及形成分层的危险。本发明还涉及一种层压层，该层压层用在包括多个组合层压层的纤维加强的层压物体和为风力涡轮机的叶片形式的纤维加强的层压物体中，其中风力涡轮机的叶片包括多个组合层压层。

Description

层压层及其切割方法和包含该层压层的层压物体
技术领域
本发明涉及一种层压层的切割方法，该层压层用于包括多个组合层压层的纤维加强的层压物体中。另外，本发明涉及一种层压层，该层压层用于包括多个组合层压层的纤维加强的层压物体中。最后，本发明还涉及为风力涡轮机的叶片形式的纤维加强的层压物体，其中所述风力涡轮机的叶片包括多个组合层压层。
背景技术
层压材料被用于多种不同的物体，其中层压物体由多个组合层压层组成。
由层压层构成的物体的一个示例是玻璃纤维物体，其中采用玻璃纤维板形式的多个层压层通常彼此叠置，并且层压层的数量取决于层压物体所需的性能。对于玻璃纤维物体而言，使用树脂将这些层保持在一起。可利用RTM(树脂传递模塑)、VARTM(真空辅助树脂传递模塑)或者其他任何适合的方法以人工的方式将树脂涂覆在层压层上。可选地，可在层铺设之前将树脂涂覆到层压层上(预浸材料)。在需要厚度不同并且从厚变化到更薄的物体的情况下，层压层的数量在一定长度上逐渐减少。出现层压层数量的这样逐渐减少能够避免凹口明显地显示并且减小在层压层上的硬度跳越，而该硬度跳越会降低层压材料的强度。
但是压层层数量的这样逐渐减少存在一个问题，即，逐渐减小的层可以分层的形式从下面的层上松开。另外，可在逐渐减少的层压层和下面的层压层之间形成气穴，这可导致层压材料起皱。分层和气穴的问题趋于使层压物体的强度减弱。另外，例如当例如使用VARTM方法时，由于沿着层压层的边缘形成沟道，而在树脂注射过程中，该沟道作为不希望的树脂分配沟道，因此形成富含树脂的区域。由于在固化过程中释放的热量可对固化过程和层压件产生不利影响，因此富含树脂的这些区域是不希望的。在最坏的情况下，在树脂硬化过程中在这样的富含树脂的区域中可形成硬化应变裂纹。
EP 1050396教导了一种设计层压物体的方法，所披露的内容示出了一种厚度不同的层压物体，其中厚度变化是由层压物体中的层数逐渐减小实现的。但是，它没有给出任何关于分层以及气穴和富含树脂区域的形成的问题的解决方案。
JP 0810528教导了一种由纤维强化的层压层构成的管状物体。为了减小分层的危险，该管在一端沿着边缘被斜切。这里在利用层压层构成物体之后对物体进行斜切，这可能涉及在斜切区域中在层之间的分层。它没有给出与厚度变化以及气穴以及富含树脂区域的形成相关的分层问题的解决方案。
发明内容
这样，本发明的目的在于提供上述问题的解决方案。
这通过一种层压层的切割方法来实现，该层压层用于包括多个组合层压层的纤维加强层压物体中，其中，至少沿着层压层的至少一个边缘的一段在层压层的厚度上进行渐尖切割，从而逐渐减小层压层的厚度。纤维加强的层压物体通常由材料板层相互叠置或者包裹构成。如果涉及的是干燥层压层被叠置的处理方法，那么本发明涉及这样一种方法，其中在还未浸渍的层压层中进行切割。但是，本发明还可用于被称为预浸材料(Prepreg)的预浸渍板。所有变型(无论干燥或者预浸材料)的共有特征是，在非硬化纤维材料上进行渐尖切割。由于不仅层压层的数量而且单个层压层的厚度都逐渐减小，因此能够制造出大大减小了关于富含树脂区域和气穴的形成的问题以及减小分层危险并且提高最终物体的强度的层压物体。
根据一个实施例，在厚度上对层压层进行渐尖切割，从而形成与在层压物体中的下面的层压层形成锐角的切口；并且在一个实施例中，层压层被以凹状曲线切割。根据另一个实施例，层压层被以凸状曲线切割。可根据层压层中的硬度条件和在层压层上的应变确定切口曲线的形状。试验表明具有锐角的渐尖切口和/或以凹状曲线或凸状曲线切割出的切口构成有利形状的曲线，从而大大地减少分层、富含树脂区域以及气穴的危险。可沿层压层的横向和/或纵向执行切割程序。
根据一个实施例，层压层为纤维层、例如玻璃纤维、碳纤维或用于塑料复合材料的其他类型纤维。纤维层或板可包括例如短切纤维(短的)、主要布置在一个方向上的(单向性的)纤维、或沿某一角度下或其他角度的两个方向彼此双轴向布置的纤维；然而，在该实施例中，纤维层也可为织造、非织造或编织材料。其尤其适用于分层问题较大的层压层，因此通过根据本发明的渐尖切口实现了针对分层问题的特别有效的解决办法。使用指形铣刀切割所述层压层。
在用于实践本发明的实验室排列中，使用特制设备如牲畜剪边机(cattle trimmer)或普通毛剪边机(ordinary hair trimmer)通过公知的指状切割技术切割层压层。但事实上，已经发现在利用本发明工作期间，完全普通的手持毛剪边机可以特别便利的方式切割层并且能够非常精确地控制切割曲线。然而，显而易见的是，需要用于切割本发明所涉及的层压层的工业设备。该设备可由例如来自于地毯工业的元件构成，其中适合的切割方法/设备用于切割出环形图案和/或切割地毯。
此外，本发明涉及一种层压层，该层压层用在包含多个组合层压层的纤维加强的层压物体中，其中层压层沿其至少一个边缘在其厚度上渐尖地切割，从而减小层压层的厚度。
此外，本发明涉及一种为风力涡轮机的叶片形式的纤维加强的层压物体，其中风力涡轮机的叶片包括多个组合层压层，其中层压层沿其至少一个边缘的一段在其厚度上被渐尖地切割，从而减小层压层的厚度。

具体实施方式
图1是包括多个组合层压层103的已知层压物体101的一部分的剖视图，其中通过层压层103数量上的变化将层压物体制造得更薄。在图1中，层压物体101最初包含六个层压层103，层压层103的数量逐渐递减为三个层压层103，由此层压物体101的厚度减半。该递减是逐渐发生的以避免造成清楚显示出凹口，这种清楚显示出的凹口将导致层压物体强度的减弱，但是也可发生在层压物体上的载荷不是太高的区域中使层压层的重量最小化。图1还示出了上层105以及由于递减而形成在上层105和下面层之间的气穴107和富含树脂的区域，所述递减可导致层压表面中的起皱。在涉及玻璃纤维层压的情况下，为了避免这些气穴，需要例如真空注射到上层105下面的多余树脂，以便将层压层103保持在一起。与已知层压物体相关的另一个问题在于递减层可与下面层以分层的形式分离。分层问题、富含树脂的区域和气穴都趋于减弱层压物体的强度，并且还趋于使得通过真空处理(诸如VARTM等)制造层压物体更为困难。
图2是根据现有技术制成的层压材料201的剖视图，其中示出了与分级递减部分205相关的分层203。
图3示出了沿层压层一部分的横截面。这里，根据本发明，在沿层压层301边缘的一段的一端303处，沿层压层302的厚度向下进行渐尖的切割。由此层压层的厚度302逐渐减小。通过进行层压层的该渐尖切割，不仅减少了层压层的数量，而且还减少了各个层压层的厚度，因此获得了可用在其中富含树脂的区域、气穴和分层的问题都显著减少的层压物体中的层压层。
渐尖的切口不应认为仅包括图3中所示的线性切割；而且还包括任何切口，在所述切口处层压层的厚度被切割以使得厚度逐渐或分级减小。在图4A-4M中示出了可选择切口的实例，其中示出了在所有切口处层压层的厚度以不同曲线形状被切割。例如可根据层压层中的强度条件和层压层上的应变确定切割的一个曲线形状。
图5是根据本发明的包括多个组合层压层503的层压物体501的一部分的剖视图，其中通过层压层503数量上的变化将层压物体制造得更薄。最初，层压物体501包含六个层压层503，层压层503的数量逐渐递减为三个层压层503，由此层压物体501的厚度减半。通过如图3中所示的那样执行层压层的渐尖切割而不是如图1中所示层压层的陡峭切割，除了减少层的数量之外，还减小了单个层压层503的厚度。在图5中所示的实例中，对层压层执行渐尖切割以与下面层形成锐角505。
图6是与图5中所示的层压物体相对应的层压物体的一部分的剖视图，在其顶部上施加有上层601。由于层压层切割的渐尖特征，使得形成在上层601与下面层之间的气穴和富含树脂区域603的出现最小化。
图7是具有内部切割层压层703的层压物体701的一部分的剖视图，即，如所看出的，切口位于穿通层压层705之间。从图中可看出，通过本发明的变化，也避免了富含树脂的区域和气穴。
图8是根据本发明的层压物体801的一段的剖视图，其包括根据本发明的多个组合层压层803。通过以凸状曲线切割层压层，除减少层压层803的数量以外，还减小了单个层压层的厚度805。
图9A-9C示出了层压物体的部分的剖视图，其中渐尖切割的层压层可有利地用在与另一个物体相连接的方面，例如与修补程序相联系。在图9A中示出了现有技术；其中希望将第一部分901与包括多个层压层905的层压体903相组合。另外，在涉及上层的情况下，层压层的陡峭切割可引起分层，也可伴随富含树脂的区域和气穴。当如图9B或9C中所示渐尖地切割层时，避免了这些问题。
图10是层压物体1001的一部分的剖视图，其中渐尖切割的层压层可有利地用在材料转换方面。这样的转换可用于材料的改变或仅使层压层1003与另一个层压层1005连续。通过在组装它们之前以渐尖方式切割层压层1003和1005，可在层之间获得更大的粘合面，而且还减小了接合处中层压层分层的危险，该危险对于陡峭切割而非渐尖或分级切割的层压层而言更高。
图11示出了为风力涡轮机的玻璃纤维叶片1101形式的层压物体。风力涡轮机的叶片1101是根据由本发明的玻璃纤维层压层构成的，从而形成强度增加的叶片，其中使得气穴最小化并使得玻璃纤维层压物体分层的危险最小化。图11示出了示为根据本发明表示斜度的横线1103形成的纵向延伸板的叶片的层压层的一部分，也称作叶片的主要层压体1102。
如果涉及为玻璃纤维或碳纤维形式的层压层的话，同样可通过使用设备例如毛剪边机通过公知的指状切割技术(finger cuttingtechnique)进行这样的切割程序。该设备可由例如来自于地毯工业的元件构成，其中适合的切割方法/装置用于切割环形图案和/或切割地毯。如图12和13中所示的，可选的切割方法可包括例如通过切割单元1203对层1201的切割，并且人员可进行研磨或切割层，从而使用所述程序进行渐尖的切割。在图中通过旋转切割单元1203切割层1201，切割单元1203具有渐尖轮廓，从而切割层压层1201以使其被渐尖地切割。如图中所示的，切割单元1203的轮廓可向一侧或两侧变尖，从而在一个切割程序中实现两个层压层的渐尖切割。在一个实施例中，层在三厘米上被逐渐切割。
应该理解的是，参照附图在说明书所描述的本发明可被修正和改变，同时所述修正和改变仍包含在所附权利要求的保护范围内。
