复合结构汽车保险杠防撞梁及制造方法,涉及车辆工程领域,解决现有汽车保险杠防撞梁采用金属材料存在质量大,能加工成形的断面形状受限,采用非金属材料存在成本高、制造效率低等问题,该汽车保险杠防撞梁结构包括外板和内板,所述外板是由钢板制成,所述内板是由碳纤维复合材料制成,将两者粘接在一起构成复合结构。本发明还同时提供了一种该复合结构汽车保险杠防撞梁低成本、高效率制造方法,本发明将钢板的低成本特性与复合材料高碰撞性能特性相结合,既有效提升了保险杠防撞梁的碰撞性能,又可大幅度降低了其结构重量；碳纤维复合材料内板可借助于钢板外层的结构形状成型,节省了模具成本,提高了成型效率。

The composite structure automobile bumper anti-collision beam and its manufacturing method relate to the field of vehicle engineering. The problem of low manufacturing efficiency, the car bumper anti-collision beam structure includes an outer plate and an inner plate, the outer plate is made of steel plate, and the inner plate is made of carbon fiber composite material, bonding the two together Form a composite structure. The present invention also provides a low-cost and high-efficiency manufacturing method of the composite structure automobile bumper anti-collision beam. The impact performance of the impact beam can greatly reduce its structural weight; the carbon fiber composite material inner plate can be formed by the structural shape of the outer layer of the steel plate, which saves the cost of the mold and improves the forming efficiency.
