Description

一种连续碳纤维增强热塑性树脂基预浸料制备装置及方法 技术领域
本发明属于复合材料领域，涉及一种连续碳纤维增强热塑性树脂基预浸料的制备技术，特别适用于熔融粘度高、对连续碳纤维布或织物渗透性差的热塑性树脂基复合材料预浸料的制备。
背景技术
作为汽车轻量化的重要手段之一，热固性碳纤维复合材料构件由于存在原材料成本高、保质期短、运输贮存条件苛刻、生产周期长、工艺成本高、易发生脆性破坏、维护修复难、材料重复利用率低、回收报废能耗高等问题，因而难以满足批量化生产的要求。为此，汽车行业对采用连续碳纤维增强热塑性树脂基预浸料热成形工艺来制造高性能热塑性碳纤维复合材料构件(CFRTP)提出了迫切需求，而连续碳纤维增强热塑性树脂基预浸料制备已成为其关键技术瓶颈之一。
目前广使用的热固性树脂基碳纤维增强预浸料生产技术主要包括：熔融法、粉末法、溶剂浸渍法等。如中国专利公开号为CN101474868A的文献中公布了一种熔融浸渍法制备连续碳纤维增强热塑性预浸带的设备，采用交错双挤出模头，从纤维两侧添加熔融热塑性树脂，但由于热塑性树脂熔融温度高、粘度大而难以保证碳纤维的均匀浸润，制得的预浸带孔隙率较大。中国专利公开号为CN102328443A的文献中提供了一种溶液浸渍法制备连续碳纤维增强热塑性预浸带的设备，设计了二次浸渍槽使纤维能在熔融树脂箱体中进一步浸渍，但未能很好地解决热塑性树脂对碳纤维丝束浸润性差的问题。中国专利公开号为CN103978695的文献中提供了一种采用粉末浸渍法制备连续功能化碳纤维增强热塑性树脂基预浸带的设备，该设备设计了可喷洒含热塑性树脂粉体悬浊液的喷洒装置，并在喷洒装置前设置了开纤装置，但该设备本质上仍是基于热压成形工艺原理，无法从根本上改变热塑性树脂基体粘性大、流动性差、难以均匀、充分浸渍碳纤维布或织物的特性，因此很难制备出纤维含量可精确控制、浸润均匀的高性能连续碳纤维增强热塑性预浸带料。
发明内容
本发明的目的是提供一种连续碳纤维增强热塑性树脂基体预浸料制备装置和方法，以解决现有连续碳纤维增强热塑性树脂基预浸料制备技术中所存在的高粘度热塑性树脂难以浸渍连续碳纤维束内部形成均匀有效粘结，从而导致所制得碳纤维复合材料构件力 学性能欠佳和承载能力较低的问题。
本发明一种连续碳纤维增强热塑性树脂基预浸料制备装置采用的技术方案是：包含卷有碳纤维束的碳纤维束卷辊和卷有树脂膜的树脂膜卷辊，碳纤维束经碳纤维束卷辊引出，从左到右依次经中心轴都前后水平布置的碳纤维束牵引辊、第一左弹性张力辊、第二左弹性张力辊、第二右弹性张力辊和第一右弹性张力辊向右输送，在第一左弹性张力辊至第一右弹性张力辊之间的碳纤维束的正上方布置有开纤器；树脂膜从树脂膜卷辊引出，从左到右依次经第二左弹性张力辊、第二右弹性张力辊和第一右弹性张力辊向右输送，树脂膜位于碳纤维束的正下方，均水平布置且相互平行，其间留有上下间隙；在第二左弹性张力辊和第二右弹性张力辊之间的树脂膜的正下方设有红外加热器，红外加热器最上部设有水平的砧板；第一左弹性张力辊、第二左弹性张力辊、第二右弹性张力辊和第一右弹性张力辊的正下端各固定连接一个垂直布置的压簧；开纤器上设置有能旋转的左楔形摆块和右楔形摆块，左楔形摆块位于第一左弹性张力辊和第二左弹性张力辊的正上方，右楔形摆块位于第二右弹性张力辊和第一右弹性张力辊的正上方；左楔形摆块的下表面是左楔形面，右楔形摆块的下表面是右楔形面，左楔面和右楔面相互面对面地布置，左楔形摆块和右楔形摆块的中间之间连接一根左右水平布置的拉簧。
本发明所述一种连续碳纤维增强热塑性树脂基预浸料制备装置的制备方法采用的技术方案是：具有以下步骤：
A、开纤器在初始位置，左楔形面最下端位于第一左弹性张力辊上方，右楔形面最下端位于第一右弹性张力辊上方，不接触第一左弹性张力辊和第一右弹性张力辊上的碳纤维束；
B、开纤器向下运动，左楔形面和右楔形面朝彼此方向摆动，最下端分别对应地接触上第一左弹性张力辊、第一右弹性张力辊上的碳纤维束，在拉簧拉力作用下对碳纤维束进行松束；
C、开纤器继续向下运动，左楔形面作用于第一左弹性张力辊，右楔形面作用于第一右弹性张力辊，左楔形摆块和右楔形摆块彼此背向摆动，拉簧拉伸，将碳纤维束张紧；同时红外加热器工作，树脂膜加热至融化；
D、开纤器再继续向下运动，左楔形面、右楔形面分别接触并下压对应位置的第二左弹性张力辊、第二右弹性张力辊，张紧的碳纤维束及树脂膜一起向下压向砧板，碳纤维束包埋入树脂膜中，制成软态碳纤维增强热塑性树脂基预浸料片。
本发明采用上述技术方案后，具有的有益效果是：
1、本发明根据张紧的风筝线切割运动物体的原理，通过左、右楔形摆块分别与第一左、右弹性张力辊配合实现碳纤维松束、开纤、张紧，通过左、右楔形摆块分别与第二左、右弹性张力辊的接触和快速下压作用，使张紧的碳纤维束对熔融态基体树脂膜进行快速垂直向下切割，并包埋入其中，实现碳纤维丝束在热塑性基体树脂中的嵌入及包埋，再通过随后压力辊的二次压实制备单向连续碳纤维热塑性预浸带料，通过二次纺织或编织，制成各种单向、双向、斜向及三维连续碳纤维增强预浸布或织物，很好地解决了热塑性树脂基体粘性大、对碳纤维束浸透性差和浸润难、树脂含量难以精确控制的问题，也适用于热固性碳纤维预浸料带制备。
2、本发明能通过对热塑性树脂膜和碳纤维束的规格设置，精确控制连续碳纤维增强热塑性预浸料中的树脂含量，获得高纤维含量的单向连续碳纤维增强热塑性预浸料，可为双向、斜向、三维预浸料的制备提供必须的中间产品，以便进一步提高碳纤维复合材料构件力学性能的可设计性。
3、本发明通过开纤器的特殊结构设计及其沿垂直方向的间歇式上下运动，顺次实现对碳纤维丝束的松束、开纤、张紧和垂直切割包埋，且碳纤维束开纤与热塑性树脂膜的非接触式、局部、红外加热方式同时进行，便于降低能源消耗，不仅节约能源，而且易于实现与其他生产单元的同步作业，实现了连续碳纤维增强热塑性预浸带料的连续、高效、自动化生产。

具体实施方式
如图1所示的本发明一种连续碳纤维增强热塑性树脂基预浸料制备装置，为左右横向布置的结构，从左到右依序是中心轴都前后水平布置的碳纤维束卷辊1、碳纤维束牵引辊3、第一左弹性张力辊4、第二左弹性张力辊6、第二右弹性张力辊7和第一右弹性张力辊5。第一左弹性张力辊4与第二左弹性张力辊6的两个中心轴之间的左右水平距离等于第一右弹性张力辊5与第二右弹性张力辊7的两个中心轴之间的左右水平距离。
碳纤维束卷辊1上卷有碳纤维束2，碳纤维束2经碳纤维束卷辊1引出后，依次经碳纤维束牵引辊3、第一左弹性张力辊4、第二左弹性张力辊6、第二右弹性张力辊7和第一右弹性张力辊5，从碳纤维束牵引辊3至第一右弹性张力辊5的碳纤维束2左右水平布置。在第一左弹性张力辊4至第一右弹性张力辊5之间的碳纤维束2的正上方布置开纤器11。开纤器11采用高压气流开纤，并能沿垂直方向作间歇式上下运动。
在第二左弹性张力辊6的左侧设置树脂膜卷辊8，树脂膜卷辊8上卷有树脂膜8，树脂膜8从树脂膜卷辊8引出，依次经第二左弹性张力辊6、第二右弹性张力辊7和第一右弹性张力辊5。第二左弹性张力辊6至第一右弹性张力辊5之间的树脂膜8左右水平布置，并且位于碳纤维束2的正下方，碳纤维束2与树脂膜8上下相互平行，其间留有上下间隙。
第二左弹性张力辊6和第二右弹性张力辊7之间的树脂膜8的正下方设置红外加热器12，红外加热器12能对树脂膜8进行加热，使树脂膜8呈熔融态基体。
第一左弹性张力辊4、第二左弹性张力辊6、第二右弹性张力辊7和第一右弹性张力辊5的每个弹性张力辊正下端各固定连接一个垂直布置的压簧，压簧上端与弹性张力辊的侧表面固定连接，压簧的下端固定在地面，在压簧的作用下，每个弹性张力辊都能沿垂直方向在径向上下运动。具体是：第一左弹性张力辊4的正下端固定连接第一左压簧34，第二左弹性张力辊6的正下端固定连接第二左压簧36，第二右弹性张力辊7的正下端固定连接第二右压簧37，第一右弹性张力辊5的正下端固定连接第一右压簧35。
开纤器11上设置有能绕左旋转销轴21旋转的左楔形摆块22和能绕右旋转销轴23旋转的右楔形摆块24，左楔形摆块22位于第一左弹性张力辊4和第二左弹性张力辊6的正上方，右楔形摆块24位于第二右弹性张力辊7和第一右弹性张力辊5的正上方。
左楔形摆块22的下表面是左楔形面32，右楔形摆块24的下表面是右楔形面33，左楔面32和右楔面33相互面对面地布置。左楔形面32和右楔形面33的楔角大小由开纤 器11向下运动的最大位移决定。左旋转销轴21和右旋转销轴23分别连接于左楔形摆块22和右楔形摆块24的上端，左楔形摆块22和右楔形摆块24的中间之间连接一根左右水平布置的拉簧25。
当开纤器11在初始原位置时，左楔形面32最下端位于第一左弹性张力辊4上方，右楔形面33最下端位于第一右弹性张力辊5上方，不接触第一左弹性张力辊4和第一右弹性张力辊5上的碳纤维束2，开纤器11向下运动后，左楔形面32和右楔形面33最下端分别对应地接触上第一左弹性张力辊4、第一右弹性张力辊5上的碳纤维束2，此时在拉簧25拉力作用下，对碳纤维束2进行松束。随着开纤器11的继续向下运动，左楔形摆块22绕左旋转销轴21顺时针旋转，右楔形摆块24绕右旋转销轴23逆时针旋转，拉簧25水平拉伸，左楔面32和右楔面33分别对应地对第一左弹性张力辊4和第一右弹性张力辊5施加向下的压力，第一左压簧34和第一右压簧35压缩，第一左弹性张力辊4和第一右弹性张力辊5向下移动，辅助左楔形摆块22、右楔形摆块24对碳纤维束2进行张紧。随着开纤器11的继续向下运动，左楔形面32同时压在第一左弹性张力辊4和第二左弹性张力辊6上的碳纤维束2上，右楔形面33同时压在第一右弹性张力辊5和第二右弹性张力辊7上的碳纤维束2上。开纤器11再继续向下运动后，第二左压簧36和第二右压簧37压缩，左楔形面32同时向下作用于第一左弹性张力辊4和第二左弹性张力辊6，右楔形面33同时向下作用于第一右弹性张力辊5和第二右弹性张力辊7，带动水平的碳纤维束2向下垂直运动，下压树脂膜8。本发明通过合理设计拉簧25以及第一左压簧34、第一右压簧35、第二左压簧36、第二右压簧37的簧力，当开纤器11快速向下运动时，在左楔形面32、右楔形面33、拉簧25以及四个压簧的共同作用下，能使张紧的碳纤维束2快速下压经红外加热器12加热后的树脂膜8，使碳纤维束2对熔融态基体树脂膜8进行垂直切割，并包埋入其中。在开纤器11向上运动时，第一左弹性张力辊4、第一右弹性张力辊5因弹簧的弹性恢复而向上运动回复原位，辅助开纤器11对碳纤维束2进行松束和开纤。
在第一右弹性张力辊5的右侧设置上压力辊13和下压力辊14，上压力辊13和下压力辊14分别上下布置。在上压力辊13和下压力辊14的右侧依次设置冷却风扇15、离型纸牵引辊19和预浸料收卷辊20。在离型纸牵引辊19的左下方设置离型纸卷辊17，离型纸卷辊17上卷有离型纸18，离型纸18依次经离型纸牵引辊19至预浸料收卷辊20。
碳纤维束2包埋入树脂膜8中后，形成软态碳纤维增强热塑性树脂基预浸料片10。由碳纤维束2和树脂膜8共同形成的该软态碳纤维增强热塑性树脂基预浸料片10经第一 右弹性张力辊5引出。从第一右弹性张力辊5引出的软态碳纤维增强热塑性树脂基预浸料片10经过上压力辊13和下压力辊14之间，上压力辊13和下压力辊14同时进一步压实软态碳纤维增强热塑性树脂基预浸料片10后形成单向连续碳纤维增强预浸带16，软态碳纤维增强热塑性树脂基预浸料片10和单向连续碳纤维增强预浸带16均水平布置，且处于同一水平高度。单向连续碳纤维增强预浸带16的正上方是冷却风扇15，对单向连续碳纤维增强预浸带16进行快速冷却。单向连续碳纤维增强预浸带16从上压力辊13和下压力辊14之间引出并冷却后再依次经离型纸牵引辊19至预浸料收卷辊20，并且单向连续碳纤维增强预浸带16紧贴在离型纸18的上表面，两者在离型纸牵引辊19处汇聚，共同经离型纸牵引辊19牵引和预浸料收卷辊20收卷。收卷后的单向连续碳纤维增强预浸带16通过编织机单元30进行二次编织，制成各种单向、双向、斜向及三维连续碳纤维预浸布或织物31。
如图2所示，在碳纤维束2松束、开纤状态时，左楔形摆块22和右楔形摆块24之间的拉簧25能调节碳纤维束2的松束力及张紧力。当开纤器11处于停止状态时，左楔形摆块22和右楔形摆块24在拉簧25的拉力作用下分别绕左旋转销轴21和右旋转销轴23反向摆动，左楔面32和右楔面33的最下端对碳纤维束2进行松束和开纤。
如图3所示，在碳纤维束2张紧、向下切割状态时，开纤器11上的左楔形摆块22和右楔形摆块24通过左楔形面32和右楔形面33分别对应地先下压第一左弹性张力辊4和第一右弹性张力辊5，并且左楔面32向左摆动，右楔面33向右摆动实现碳纤维束2的张紧，然后再通过下压第二左弹性张力辊6和第二右弹性张力辊7，带动碳纤维束2垂直向下运动，使碳纤维束2对正下方的熔融态基体树脂膜8实现垂直切割和包埋。
如图4所示，红外加热器12通过控制线连接温控仪29，温控仪29用于控制红外加热器12的启停。红外加热器12内部具有温度传感器28和多根红外加热灯管26，温度传感器28与温控仪29相连，多根红外加热灯管26用于对树脂膜9进行局部、快速、辐射式加热。红外加热器12的最上部设有水平的砧板27，砧板27的左右宽度与所制备的单向连续碳纤维增强预浸带16的左右宽度一致，砧板27用相应的耐高透光率、高温热传导率的材料制成，砧板27上表面和第二左弹性张力辊6、第二右弹性张力辊7下压前时树脂膜9下表面之间留有一定的上下垂直距离，该上下垂直距离h为1-2mm，便于树脂膜9的顺利供给。
如图1-4所示，制备连续碳纤维增强热塑性树脂基预浸料时，先备好12K碳纤维束卷、PA66热塑性树脂膜卷及yc-lxz001离型纸卷，分别置于对应的碳纤维束卷辊1、树脂 膜卷辊8及离型纸卷辊17上。将碳纤维束2从纤维束卷辊1引出，预先从左至右依次绕在碳纤维束牵引辊3、第一左弹性张力辊4、第二左弹性张力辊6、第二右弹性张力辊7、第一右弹性张力辊5、上压力辊13和下压力辊14之间、离型纸牵引辊19、预浸料收卷辊20上，使碳纤维束2从左向右输送。将树脂膜9从树脂膜卷辊8引出，预先从左至右依次绕在第二左弹性张力辊6、第二右弹性张力辊7、第一右弹性张力辊5、上压力辊13和下压力辊14之间、离型纸牵引辊19、预浸料收卷辊20上，使树脂膜9从左向右输送，并且树脂膜9有间隙地位于碳纤维束2的正下方，两者之间不接触。将离型纸18从离型纸卷辊17引出，预先依次绕在离型纸牵引辊19、预浸料收卷辊20上，使离型纸18向右输送。
当碳纤维束2输送至开纤器11下方时，左楔形摆块22、右楔形摆块24在拉簧25作用下分别绕左旋转销轴21、右旋转销轴23朝彼此方向摆动，即左楔形摆块22朝逆时针方向摆动，右楔形摆块24朝顺时针方向摆动，同时左楔形面32和右楔形面33的最下端分别对应地接触于第一左弹性张力辊4、第一右弹性张力辊5上的碳纤维束2，实现碳纤维束2的松束，同时采用高压气流对碳纤维束2进行开纤，参见图1和图2。
当树脂膜9输送至红外加热器12上方时，红外加热器12工作，通过非接触加热方式对树脂膜9进行局部快速加热至融化。
开纤器11向下运动，左楔形摆块22的左楔形面32作用于对应位置的第一左弹性张力辊4，右楔形摆块24的右楔形面33作用于对应位置的第一右弹性张力辊5，带动拉簧25拉伸，使左楔形摆块22、右楔形摆块24绕对应的左旋转销轴21、右旋转销轴23彼此背向摆动，将碳纤维束2张紧，参见图1和图3。
开纤器11再继续向下运动，左楔形摆块22、右楔形摆块24分别接触并下压对应位置的第二左弹性张力辊6、第二右弹性张力辊7，使张紧的碳纤维束2及第二左弹性张力辊6和第二右弹性张力辊7之间的已经加热融化的热塑性树脂膜9一起快速向下，压向红外加热器12上的砧板27，在此过程中，碳纤维束2对位于其下方的树脂膜9进行垂直切割，并且碳纤维束2包埋入树脂膜9中，如此预制成了软态碳纤维增强热塑性树脂基预浸料片10。
开纤器11向上运动回程，其上的左楔形摆块22、右楔形摆块24先与第二左弹性张力辊6、第二右弹性张力辊7脱离接触，再与第一左弹性张力辊4、第一右弹性张力辊5脱离接触，开纤器11回程至初始位置，停止运动，完成一个工作循环。最后将碳纤维束2和树脂膜8分别向前运送一个步距，即运送第二左弹性张力辊6和第二右弹性张力辊7 中心轴之间的水平距离后，开纤器11再次先对碳纤维束2进行松束、开纤，然后开纤器11再次向下运动，将碳纤维束2张紧以及使张紧的碳纤维束2对树脂膜9进行垂直切割，如此循环往复连续工作循环，实现软态碳纤维增强热塑性树脂基预浸料片10的制备。
参见图1，制备好的软态碳纤维增强热塑性树脂基预浸料片10继续向前行进并在上压力辊13和下压力辊14之间经进一步压实，然后在冷却风扇15的快速冷却下制成单向连续碳纤维增强预浸带16，单向连续碳纤维增强预浸带16在离型纸牵引辊19处与离型纸18汇聚后，经预浸料收卷辊20收卷。编织单元30对预浸料收卷辊20收卷的单向连续碳纤维增强预浸带16进行二次编织，制成各种单向、双向、斜向及三维连续碳纤维预浸布或织物31。
以上所述仅为本发明的一个实施例，以便有助于本领域技术人员进一步理解本发明，不以任何形式限制本发明。在不脱离本发明构思前提下，对本发明所做的各种非实质性改进和替换，如所使用增强纤维、树脂膜种类的拓展或装备结构的改造等，均属于本发明的保护范围。
