The invention belongs to the technical field of automobile body lightweight, and particularly relates to a waterproof and fireproof automobile body lightweight foamed aluminum material which comprises a buffering foamed aluminum plate, wherein magnesium alloy plates are arranged on the upper side and the lower side of the buffering foamed aluminum plate correspondingly, anti-bending foamed aluminum plates are arranged on the upper side of the magnesium alloy plate on the upper side and the lower side of the magnesium alloy plate on the lower side, aluminum alloy plates are arranged on the upper side of the anti-bending foamed aluminum plate on the upper side and the lower side of the anti-bending foamed aluminum plate on the lower side, the density of the buffering foamed aluminum plate is different from that of the anti-bending foamed aluminum plates, the density of the buffering foamed aluminum plate is different from that of the anti-bending foamed aluminum plate, the anti-bending foamed aluminum plate with the large density has the characteristic of high anti-bending strength, the buffering foamed aluminum plate with the low density has the advantages of high damping and shock absorption performance and high impact energy absorption rate, the buffering foamed aluminum plate and the anti-bending foamed aluminum plate with the different densities are used at the same time, and light weight of the automobile body is achieved while the requirements of an automobile body are met.

    本发明公开的属于汽车车体轻量化技术领域,具体为一种防水防火的汽车车体轻量化泡沫铝材料,包括缓冲泡沫铝板,所述缓冲泡沫铝板的上下侧均设置有镁合金板,上侧所述镁合金板的上侧及下侧镁合金板的下侧均设置有抗弯泡沫铝板,上侧所述抗弯泡沫铝板的上侧及下侧抗弯泡沫铝板的下侧均设置有铝合金板,所述缓冲泡沫铝板的密度和抗弯泡沫铝板的密度不同,缓冲泡沫铝板和抗弯泡沫铝板的密度不同,密度较大的抗弯泡沫铝板具有高抗弯强度的特点,密度较低的缓冲泡沫铝板具有高阻尼减震性能及冲击能量高吸收率的优点,通过密度不同的缓冲泡沫铝板和抗弯泡沫铝板同时使用,可以在满足汽车车体要求的同时还实现汽车车体的轻量化。
