The invention belongs to the technical field of vehicle fuel tanks, and discloses a composite fuel tank and a manufacturing method thereof.The composite fuel tank comprises a tank body and an end cover, the tank body and the end cover are bonded to form a closed structure after being formed respectively, and the tank body and the end cover are formed through an autoclave forming technology. According to the manufacturing process, the end cover and the box body are combined, the box body and the end cover are formed respectively, and then the end cover and the box body are assembled in a bonding mode. And when the carbon fiber composite material is paved, a secondary paving process is adopted, so that the sealing performance of the product is improved, and the problem of insufficient sealing performance possibly caused by split paving is avoided.

    本发明属于车辆油箱技术领域,公开了一种复合材料油箱及其制造方法,包括箱体和端盖,箱体和端盖分别成形后粘接为封闭结构,箱体和端盖的成形采用热压罐成形工艺。本发明制造工艺采用端盖与箱体组合,分别对箱体和端盖进行成形,后对端盖与箱体进行粘接装配。在碳纤维复合材料铺贴时,采用二次铺贴工艺,提高产品的密封性,避免分体铺贴可能产生的密封性不够的问题。
