S3、侧围外板制作与连接:纤维原料从自动下料机下料后,放入侧围外板成型模具中,使侧围外板成型,通过结构胶将已成型的侧围外板与步骤S2中已成型的空心加强梁-侧围内板粘接,完成制造。

具体实施方式
请参阅图1、3、4所示,一种碳纤维复合材料的氢能汽车A柱结构,包括空心加强梁3、侧围外板1和侧围内板2,空心加强梁3、侧围外板1和侧围内板2均采用碳纤维复合材料制作,所述空心加强梁3在周向仅有一个粘合翻边,所述侧围内板2与空心加强梁3通过共固化方式连接装配,以确保空心加强梁3与侧围内板2之间粘接可靠,也减少了装配工作量,所述侧围外板1与空心加强梁3和侧围内板2均通过结构胶粘接,使所述侧围外板1与所述侧围内板2相向包覆空心加强梁3,从而实现侧围总成的加强。
所述空心加强梁3采用预浸料加压带压工艺或RTM工艺成型。所述侧围外板1和侧围内板2均采用预浸料热压罐工艺或RTM工艺成型。预浸料加压带压工艺和预浸料热压罐工艺所使用的纤维原料为预浸料,RTM工艺成型所使用的纤维原料为干纤维布。
所述空心加强梁3与侧围内板2之间的空隙通过纤维原料填充,且所填充的纤维原料沿空心加强梁3管腔的0°方向。填充区域4为两处。填充后,结构胶胶层5在空心加强梁3与侧围内板2之间的空隙处具有贴附面。
请参阅图2、3、4所示,上述碳纤维复合材料的氢能汽车A柱结构的制造方法,包括如下步骤:
S1、预制空心加强梁3:
S1.1、纤维原料从自动下料机下料后,在平板上进行铺覆;
S1.2、将平板上完成铺覆的纤维原料叠层,使其两头重叠,在重叠前预先放入真空袋8;
S1.3、将两头重叠区域通过纤维进行缝合,完成空心加强梁3预成型体的制作,考虑到空心加强梁3可能存在变截面,因此缝合区域需根据空心加强梁3局部截面大小进行必要调整,通过纤维进行缝合后,可以防止空心加强梁3在受到弯曲载荷时开胶;
S1.4、将空心加强梁3预成型体放入模具中加压成型,具体的,采用预浸料加压带压工艺时,上模6与下模7对模将空心加强梁3预成型体的缝合区域9模压成型,上模6与下模7对模完成后,通过预先放入的真空袋8加压,采用RTM工艺成型时,上模6与下模7对模完成后,先给真空袋9一定压力,使得空心加强梁3预成型体与模具面贴合,再注入树脂,树脂注入完成之后,再给真空袋9施加固化所需压力;
S2、侧围内板2制作与连接:纤维原料从自动下料机下料后,放入侧围内板2的成型模具中,同时放入步骤S1.4中已成型的空心加强梁3,并在空心加强梁3与未成型的侧围内板2之间的空隙中填充纤维原料,加压使侧围内板2成型且侧围内板2与空心加强梁3共固化粘接;
S3、侧围外板1制作与连接:纤维原料从自动下料机下料后,放入侧围外板1成型模具中,使侧围外板1成型,通过结构胶将已成型的侧围外板1与步骤S2中已成型的空心加强梁3-侧围内板2粘接,完成制造。
铺覆纤维原料时,沿空心加强梁3长度方向的纤维原料铺层不小于垂直空心加强梁3长度方向的纤维原料铺层,也就是说,沿空心加强梁3长度方向的纤维原料铺层占多数,而且沿空心加强梁3长度方向的纤维原料连续,以保证空心加强梁3的力学性能。铺覆时,不考虑零件的曲率。
当然,以上仅为本发明较佳实施方式,并非以此限定本发明的使用范围,故,凡是在本发明原理上做等效改变均应包含在本发明的保护范围内。
