The invention relates to a preparation method of a vehicle door anti-collision beam, a preparation method of the vehicle door anti-collision beam and a vehicle door anti-collision beam assembly. The preparation method comprises the following steps: preparing a first glass fiber composite material layer on the surface of a foam core layer to obtain a first middle anti-collision beam; preparing a carbon fiber composite material layer on the surface of the first glass fiber composite material layer of the first middle anti-collision beam to obtain a second middle anti-collision beam; and preparing a second glass fiber composite material layer on the surface of the carbon fiber composite material layer of the second middle anti-collision beam. According to the vehicle door anti-collision beam prepared through the method, the collision requirement of a vehicle door is met, and meanwhile the weight of the vehicle door anti-collision beam can be reduced by 70% or above compared with a traditional anti-collision beam; and meanwhile, the sectional area is small, and arrangement of vehicle door accessories is not affected; and the cost is relatively low. Furthermore, by adopting the pultrusion and winding forming processes, the automatic production of the product can be realized, a traditional high-strength steel and aluminum alloy profile anti-collision beam can be completely replaced, and the vehicle door anti-collision beam is particularly suitable for being used as an vehicle door anti-collision beam of an aerocar.

    本申请涉及一种车门防撞梁的制备方法及其制备方法和车门防撞梁组件。上述制备方法包括以下步骤:在泡沫芯层表面制备第一玻纤复合材料层,得到第一中间防撞梁;在所述第一中间防撞梁的第一玻纤复合材料层表面制备碳纤复合材料层,得到第二中间防撞梁;在所述第二中间防撞梁的碳纤复合材料层表面制备第二玻纤复合材料层。按照本申请的方法制备的车门防撞梁,在满足车门的碰撞要求的同时,重量可以做到比传统防撞梁轻约70%以上;同时截面积较小,不影响车门附件的布置;且成本也比较低。进一步地,通过采用拉挤成型和拉缠成型工艺,可以实现产品的自动化生产,完全可以替代传统的高强钢和铝合金型材防撞梁,特别适合作为飞行汽车的车门防撞梁。
