The invention discloses a fabrication method for an automobile seat mounting cross beam and belongs to the field of automobile part production. The method comprises the steps that a first mold for fabricating the automobile seat mounting cross beam is obtained, a carbon fiber prepreg is laid on a reinforcing area on the surface of a groove of the first mold, and a reinforcing layer is formed; thecarbon fiber prepreg is continuously laid on the whole groove area in the groove where the reinforcing layer is formed, and a body appearance layer is formed; the laid first mold is subjected to curing treatment, and a preformed part is obtained; and secondary shaping is performed on the preformed part to obtain the automobile seat mounting cross beam. According to the automobile seat mounting cross beam and the fabrication method thereof and an automobile, a seat mounting cross beam body is formed at a time through few molds, and the subsequent welding and splicing procedures are omitted; meanwhile, weak areas are correspondingly reinforced in the laying process, reinforcing pieces do not need to be additionally arranged, and the traditional fabricating process is simplified. and in addition, the carbon fiber seat mounting cross beam is light in weight and meets the requirement for lightness of the whole automobile.
本发明公开了一种汽车座椅安装横梁的制作方法,属于汽车零部件生产领域。该方法包括:获取制作汽车座椅安装横梁的第一模具,使用碳纤维预浸料在第一模具的凹槽表面上对加强区域进行铺设,形成加强层;在形成加强层的凹槽中继续使用碳纤维预浸料对整个凹槽区域进行铺设,形成本体外形层;对铺设后的第一模具进行固化处理,获得预成型件;对该预成型件进行二次定型,获得汽车座椅安装横梁。使用较少的模具一次成型出座椅安装横梁本体,省去了后续的焊接拼接工序。同时在铺层时对薄弱区域相应地进行了补强,无需另外设置加强件,简化了传统的制作工艺。并且,碳纤维座椅安装横梁重量较轻,符合汽车整车轻便化的需求。
