The invention discloses a battery pack bottom protection plate and a preparation method thereof.The battery pack bottom protection plate comprises a first protection layer, an anti-impact layer and a second protection layer, and the anti-impact layer is arranged between the first protection layer and the second protection layer; the first protective layer and the second protective layer respectively comprise a continuous fiber reinforced bio-based high-temperature polyamide composite material. Therefore, the battery pack bottom protection plate has excellent mechanical properties, and the risk that the battery protection bottom plate is impacted to be layered and hollow is reduced.

    本发明公开了一种电池包底护板及其制备方法,该电池包底护板包括第一防护层、抗冲层和第二防护层,所述抗冲层在所述第一防护层和所述第二防护层之间,所述第一防护层和所述第二防护层分别包括连续纤维增强生物基高温聚酰胺复合材料。由此,该电池包底护板具有优异的力学性能,并且降低了电池防护底板受冲击分层空鼓的风险。
