The invention relates to a composite board and a manufacturing method thereof, a vehicle structural member and a vehicle, the composite board comprises a first copper alloy layer, a damping layer and a second copper alloy layer, the damping layer is arranged between the first copper alloy layer and the second copper alloy layer, and the first copper alloy layer and/or the second copper alloy layer comprises at least one of copper, tin, magnesium and rare earth metal. By adding different alloy elements, the corrosion resistance of the copper alloy can be improved, meanwhile, the copper alloy inherits the ductility of pure copper, cold machining and hot machining can be conducted, and products of various shapes can be manufactured. In addition, the damping layer is made of high polymer materials and can play roles in bonding the upper copper alloy layer and the lower copper alloy layer and reducing vibration and noise. According to the composite board, the copper alloy and the damping layer are compounded, so that the board is suitable for the composite damping sound insulation board needing resistance welding.
一种复合板件及其制作方法、车辆结构件、车辆,复合板板件包括第一铜合金层、阻尼层和第二铜合金层,阻尼层设置在第一铜合金层和第二铜合金层之间,第一铜合金层和/或第二铜合金层中包括铜,以及锡、镁和稀土金属三者中的至少一种。通过添加不同的合金元素可以提高铜合金的耐蚀性,同时铜合金还继承了纯铜的延展性,可以进行冷加工和热加工,制成各种形状的产品。此外,阻尼层有高分子材料制成,能够起到粘合上下铜合金层和减震降噪的作用。所以本发明通过提供的复合板件采用铜合金和阻尼层复合,使得该板件适用于需要进行电阻焊接的复合阻尼隔音板。
