The present invention provides a battery pack bottom protection plate and a molding process, and belongs to the technical field of battery packs, the battery pack bottom protection plate comprises a battery pack protection plate sheet material, the battery pack protection plate sheet material sequentially comprises an upper surface layer stack, a PP honeycomb layer, a steel plate and a lower surface layer stack from top to bottom, the upper surface layer stack comprises at least two upper glass fiber layers, and the lower surface layer stack comprises at least two lower glass fiber layers; the upper layer stack at least comprises two upper glass fiber layers, the lower layer stack at least comprises two lower glass fiber layers, a metal net is arranged between the two lower glass fiber layers, the laying angles of the thermoplastic composite material sheets in the two upper glass fiber layers are the same, and the laying angles of the thermoplastic composite material sheets in the two lower glass fiber layers are the same. The metal net is added in the lower surface layer stack, so that the strength of the lower glass fiber layer is improved, and the formed battery pack bottom protection plate has relatively high impact resistance and scratch resistance.
本发明提供了一种电池包底护板及成型工艺，属于电池包技术领域，包括：电池包防护板板材，且该电池包防护板板材由上至下依次包括上面层堆栈、PP蜂窝层、钢板以及下面层堆栈，且上面层堆栈至少包括两层上玻璃纤维层，下面层堆栈至少包括两层下玻璃纤维层，并在两层下玻璃纤维层之间设置有金属网，其中，两层上玻璃纤维层中热塑性复合材料片材铺设角度相同，两层下玻璃纤维层中热塑性复合材料片材铺设角度相同。本发明通过在下面层堆栈中添加金属网，以此提高下玻璃纤维层的强度，使得成型后的电池包底护板具有较强的抗冲击力和抗刮蹭性能。
