The invention discloses a lightweight vehicle body material and a preparation method thereof, and belongs to the technical field of vehicle body materials. The light-weight vehicle body material is composed of multiple layers and comprises a foam aluminum alloy inner layer set, carbon fiber powder modified polydicyclopentadiene sheet layers are arranged on the two outer sides of the foam aluminum alloy inner layer set respectively, the foam aluminum alloy inner layer set comprises at least two foam aluminum alloy inner layers, and an aluminum alloy interlayer is arranged between every two adjacent foam aluminum alloy inner layers. The foamed aluminum alloy can effectively enhance the mechanical property of the whole material, solves the technical problem of poor mechanical property of single foamed aluminum alloy, gives full play to the advantages of light weight and sound absorption of the foamed aluminum alloy, and is suitable for being used as a vehicle body material of a lightweight vehicle.

    本发明公开了一种轻量车体材料及其制备方法,属于车体材料技术领域。本发明轻量车体材料由多层构成,包括泡沫铝合金内层组,泡沫铝合金内层组的两外侧分别设有碳纤维粉改性聚双环戊二烯片层,泡沫铝合金层内组包括至少两个泡沫铝合金内层,每相邻两个泡沫铝合金内层之间设有铝合金夹层,能够有效增强整个材料的机械性能,解决了单一泡沫铝合金的机械性能较差的技术问题,同时,充分发挥了泡沫铝合金的轻量、吸音的优点,适合作为轻量化车辆的车体材料使用。
