According to the preparation method of the PP honeycomb composite reinforced steel protection plate, the steel plate with the thickness of 0.6-1.0 mm can be effectively compounded with the PP honeycomb core, the glass fiber plate and the like, and the prepared PP honeycomb composite reinforced steel protection plate has the buffering and energy absorbing effects, is high in strength and can effectively prevent a power battery pack tray from being damaged by external force impact and collision. The method comprises the following steps: a, coating adhesive films on the upper and lower surfaces of a steel plate; b, bonding and compounding the PP honeycomb core and a steel plate with the thickness of 0.6-1.0 mm to form a middle interlayer; c, at least two layers of continuous glass fiber reinforced thermoplastic PP unidirectional prepreg tapes are placed on the upper surface and the lower surface of the middle interlayer respectively to form a pressed blank, and the extending directions of glass fibers in the adjacent continuous glass fiber reinforced thermoplastic PP unidirectional prepreg tapes are perpendicular to each other; and d, carrying out hot pressing on the pressed blank, and then cooling and shaping to obtain the PP honeycomb composite reinforced steel protection plate with mutually bonded layers.

    本发明提供一种PP蜂窝复合增强钢防护板的制备方法,该方法能够把厚度0.6‑1.0mm钢板与PP蜂窝芯、玻璃纤维板等有效复合,制得的PP蜂窝复合增强钢防护板具有缓冲吸能作用,且强度高,能够对有效防止外力冲击和磕碰对动力电池包托盘的损伤。它包括以下步骤:a、在钢板上下表面覆上胶膜;b、把PP蜂窝芯与厚度0.6‑1.0mm钢板粘接复合形成中间夹层;c、在中间夹层上表面和下表面上分别放置至少两层连续玻璃纤维增强热塑性PP单向预浸带形成压坯,相邻的连续玻璃纤维增强热塑性PP单向预浸带中的玻璃纤维的延伸方向相互垂直;d、把压坯进行热压,然后冷却定型得到各层相互粘接的PP蜂窝复合增强钢防护板。
