具体实施方式
参照前面的图1-7,通常用附图标记1来指代适合实现复合制造方法的叠置的工装设备。叠置的工装设备1包括第一模具框架2和第二模具框架8。第一工装模具3可以被设置在第一模具框架2上,第二工装模具9可以被设置在第二模具框架8上。第一工装模具3和第二工装模具9可以是液压致动的,以便有助于第一工装模具3和第二工装模具9朝向和远离彼此运动。第一工装模具3可以具有第一成型模具表面4,而第二工装模具9可以具有与第一工装模具3的第一成型模具表面4互补的第二成型模具表面10。
如图6所示,多个感应线圈26可以延伸穿过每个第一工装模具3(和第二工装模具9,未示出)以便有助于选择性加热第一工装模具3和第二工装模具9。温控系统27可以与感应线圈26相连。第一模具承受器20可以与第一工装模具3的感应线圈26热耦合。第二模具承受器21可以与第二工装模具9的感应线圈26热耦合。第一模具承受器20和第二模具承受器21均可以是热传导材料,例如但不限于铁磁性材料、钴、镍或者它们的化合物。如图1-5所示,第一模具承受器20一般可以与第一成型模具表面4相符合,第二模具承受器21一般可以与第二成型模具表面10相符合。
如图6所示,第一工装模具3的第一成型模具表面4上和第二工装模具9的第二成型模具表面10上提供有电和热绝缘涂层30。电和热绝缘涂层30可以是例如氧化铝或金刚砂/碳化硅。第一模具承受器20可以设置在第一工装模具3的电和热绝缘涂层上,同样,第二模具承受器21可以设置在第二工装模具9的电和热绝缘涂层30上。
如图1-5所示,冷却系统14可以设置在每个第一工装模具3和第二工装模具9内。冷却系统14可以包括例如冷却液导管15,其具有遍布每个第一工装模具3和第二工装模具9的选定分布。如图4所示,冷却液导管15适于使得冷却介质17流入第一工装模具3或者第二工装模具9中。冷却介质17可以是液体、气体或者气/液混合物,例如被用作喷雾或气溶胶的介质。
每个第一工装模具3和第二工装模具9均可以包括多个叠置的金属板28,例如修整成适合感应线圈26尺寸的不锈钢。这在图6和图7中示出。叠置的金属板28可以被定向成相对于第一成型模具表面4和第二成型模具表面10大体呈垂直关系。每个金属板28的厚度可以从大约1/16英寸到大约1/4英寸,例如优选地是1/8英寸。相邻的叠置的金属板28之间有空气间隙29,用以有助于冷却第一工装模具3和第二工装模具9。可以使用夹具(未示出)、紧固件(未示出)和/或本领域技术人员所公知的其他合适技术使得叠置的金属板28彼此相连。可以根据它们的电和热特性来选择叠置的金属板28,而且对于磁场而言叠置的金属板28可以是可透过的。在每个叠置的金属板28的每一侧上均可以选择地具有电绝缘涂层(未示出),以防止在叠置的金属板28之间有电流流过。绝缘涂层的材料可以是例如陶瓷或其它抗高温材料。但是,如果在叠置板中间存在空气间隙,则涂层就没有必要了。如图6所示,在每个标出的板28上具有多个热膨胀槽40,从而有助于叠置的工装设备1的热膨胀和收缩。
如图1所示,在复合制造方法的典型实施方式中,模塑化合物24首先被放置在叠置工装设备1的第一工装模具3和第二工装模具9之间。接下来,如图2所示,当感应线圈26(图6)加热第一工装模具3和第二工装模具9以及第一模具承受器20和第二模具承受器21时,第一工装模具3和第二工装模具9朝向彼此运动。因此,当第一工装模具3和第二工装模具9彼此靠近时,第一模具承受器20和第二模具承受器21快速加热模塑化合物24。因此如图2所示,随着第一工装模具3和第二工装模具9不断接近并闭合抵住模塑料24,模塑化合物24可以被热塑成型为复合板25的形状(如图3-5所示),其形状可以由第一工装模具3的第一成型表面4和第二工装模具9的第二成型表面10限定。
如图4所示,冷却系统14接下来运转从而将冷却介质17施加于第一工装模具3和第二工装模具9以及第一模具承受器20和第二模具承受器21。因此,冷却介质17有效地和快速地冷却了第一工装模具3和第二工装模具9以及第一模具承受器20和第二模具承受器21,并且还冷却了夹在第一模具承受器20和第二模具承受器21之间的复合板25。复合板25在预设时间周期内保持夹在第一模具承受器20和第二模具承受器21之间,直到复合板25被完全冷却。这样使得被模塑成型和加固后的复合板25在如图5所示的第一工装模具3和第二工装模具9打开后,保持由第一成型表面4和第二成型表面10限定的结构形状。当复合板25在合适的特性增强率下被冷却时,成型和冷却的复合板25从叠置的工装设备1中移出且不会损失复合板25的尺寸精度或者产生分层。
现将注意力转向图8-14,其示意了可以被用于模塑成型复合零件58a(图13)的树脂传递模塑成型设备1a。与之前图1-7描述的大致相似的一对工装模具28分别固定在模塑压盘42和44上,从而允许模具28被打开和关闭。类似前面描述的实施例,模具28包括多个被空气间隙隔开的叠置的金属板28a,空气间隙构成了板28a之间的通道29。如前所述,使用空间隔开的金属板28a减少了模具组件1a的总热质,并且有助于成型零件58a更快速地冷却。
模具28包括了感应加热线圈26,当模具28关闭时,所述线圈26被插座连接件45电连接在一起。模具28有相对的表面,所述相对的表面被成型并且与一对承受器20a和21a的成型模塑表面31(图10)大致匹配。承受器20a和21a的成型模塑表面31与那些完成的复合零件58a相匹配,并且形成了模塑腔33。承受器20a和21a通过分别与介电壳46和48相关联而电绝缘于模具28,所述绝缘壳可以包括例如但不限于氧化铝或金刚砂。承受器20a和21a可以包括一种热传导材料,例如但不限于铁磁性材料、钴、镍或者它们的化合物。水冷座53与承受器20a和20b的下外缘接触,从而辅助冷却承受器20a和20b,下面会加以叙述。线圈26和冷却系统14由适合的温控系统65控制,该温控系统65控制对承受器20a和20b的加热和冷却。
树脂传递系统55包括了树脂源,该树脂源连同泵50一起用来将树脂输运到模塑组件1a。在一些情况下,在树脂通过供给线54被输运到模塑腔33之前,可以在树脂中加入催化剂,并在前置混合器52处合并并进行混合。树脂可以包含树脂转移模塑成型中常用的任意树脂,包括但不限于聚酯、乙烯基酯、环氧树脂、酚醛树脂和甲基丙烯酸甲酯树脂,如果需要,还可以包含色素和添加剂。
如图9所示,树脂供给线54与承受器20a和介电壳46上的对齐开口47相连。但是,供给线54也可以在承受器20a的其它地方与模塑腔33相连,从而允许树脂流入模塑腔33。例如,供给线54可能与承受器20a的沿着法兰部分57的开口(未示出)相连接。
为了保证模塑腔33完全充满树脂,采用排出线56使过剩的和溢流的树脂离开模塑腔33。在图示例子中,排出线56与承受器21a和介电壳48法兰部分61上的对齐开口51相连。其它的使过剩的树脂从模塑腔33中移出的技术包括提供密封件59,其中该密封件59具有如下特征,即正好密封模塑腔33,但由于加压树脂对密封件59施加的压力,又稍微屈服以允许过剩的或溢流的树脂从模塑腔中流出。密封件59可以但不仅限于由弹性体材料构成。
现在同时参考图8-14,树脂传递模塑成型方法从步骤62(图14)开始,即在模具28上安装承受器20a和21a,并将预成型件58载入模具腔33。预成型件58可以包括连续丝、布、编织纱、长纤维或短切原丝形式的干燥纤维加固物,其中任何一种均可以是但不限于玻璃、碳、芳酰亚胺或它们的组合。图9显示已经安装的承受器20a和20b,并且纤维预成型件58被装入模塑腔33中。接下来,在步骤64中,如图11所示模具28关闭,因而关闭了承受器半模20a和21a,导致模塑腔33密闭。当模具28关闭时,线圈26被插座连接件45电连接。密封件59围绕承受器20a和21a的外围密封模塑腔33。承受器20a和21a被密封后,模塑腔33通过出口56或与排放系统63相连的其它真空连接件(未示出)而进行排放,从而在模塑腔33内形成负压。
在步骤66,感应线圈26被励磁,使得承受器20a和21a被感应加热到一定温度。当承受器20a和21a已经被加热到阈值温度时,如步骤68所示,树脂从树脂源50通过前置混合器52被抽出,并且经过供给线54流入模塑腔33。模塑腔中的负压有助于将树脂从供给线54抽入到模塑腔33内。进入模塑腔33的树脂流过并注入干燥预成型件58。在模塑腔33被填满之前,树脂在一定压力下连续流入模塑腔33。任何过剩的树脂可以通过排出线56或者通过穿过可以少量屈服的密封件59离开模塑腔33,从而允许过剩树脂流经。在必要的时间段内承受器20a和21a保持高温以作为工艺的一部分从而固化被注入的预成型件58。
承受器20a和21a已经保持必要温度经过了一段指定时间长度之后,如图12和图14所示,在步骤70零件58a被冷却。这个冷却过程可以包括接合冷却系统14,其中例如流体、空气等的冷却媒质从喷嘴15排出。冷却介质流过通道29,流经介电壳46和48的表面,从而冷却承受器20a和21a,并且将热从完成的零件58a带走。
最后,如图13和图14所示,剩下的步骤72包括分开模具28并且将完成的零件58a从模塑腔33中移出。因为承受器20a和21a已经被快速冷却,因此它们可以被快速取出并更换为具有不同形面的承受器,以便模塑成型不同的零件并增加生产率。
下面参考图15和图16,本发明的实施例可以用在如图15所示飞行器制造和服役方法74和图16所示的飞行器上。本发明实施例在飞行器上的应用包括例如不限于复合加固构件,例如机身蒙皮、机翼蒙皮、控制表面、舱门、地板、门板、登机门和尾翼,这里仅列出一些。在预生产阶段,示例性方法74可以包括飞行器76的规格和设计78以及材料采购80。在生产阶段,进行飞行器76的部件和子组件的生产82和系统整合84。此后,飞行器76可以进行认证和交货86以便开始服役88。在客户使用过程中,对飞行器76制定了例行维护和维修90(还可能包括改进、重构和翻新等等)。

在生产和服役方法74的任何一个或更多个阶段期间可以应用这里描述的设备。例如,与生产过程82相关的部件或子组件可以以与飞行器76处于服役状态时所生产的部件和子组件相类似的方式被生产或制造。并且,例如可以在生产阶段82和84中使用一个或更多个设备实施例,从而基本加快飞行器76的组装或降低其成本。类似地,可以在飞行器76处于服役状态时使用一个或更多个设备实施例,例如但不限于是为了维护和维修90。
尽管这里描述的本发明的实施例是关于某些范例的实施例,但应该理解的是,具体实施例是为了举例目的而不是限制性目的,因为本领域的技术人员将意识到其它变型。
