The invention relates to a light-weight truck side apron board and an integral forming method. Comprising the following steps: placing a plurality of light core plates at intervals, pulling fiber yarns and fiber fabrics impregnated with a first resin liquid to a position between two adjacent core layers, and enabling the fiber yarns and the fiber fabrics impregnated with a second resin liquid to circumferentially surround the plurality of light core plates, synchronously pulling the light core plate, the fiber yarns and the fiber fabrics which are impregnated with the first resin liquid and the fiber yarns and the fiber fabrics which are impregnated with the second resin liquid into a mold, heating and curing, and obtaining the light truck side apron board through a pultrusion process; wherein the curing temperature (T1) of the first resin liquid is lower than the curing temperature (T2) of the second resin liquid, and T2-T1 is higher than 40 DEG C; through the structural design of the light truck side apron board, the technical problems that in the prior art, an existing mainstream truck side apron board is mainly made of aluminum alloy materials, although the existing mainstream truck side apron board has the effects of guiding flow and reducing wind resistance, the weight is large, and the installation cost is high are solved.
本发明涉及一种轻量化卡车侧裙板及一体成型方法;包括如下步骤:将多个轻质芯板间隔摆放,将经第一树脂液浸渍的纤维纱和纤维织物牵引至相邻两芯层间,将经第二树脂液浸渍的纤维纱和纤维织物周向环绕多个轻质芯板,轻质芯板、经第一树脂液浸渍的纤维纱和纤维织物、经第二树脂液浸渍的纤维纱和纤维织物同步牵引进模具,加热固化,通过拉挤成型工艺获得轻量化卡车侧裙板;其中,第一树脂液固化温度(T1)小于第二树脂液的固化温度(T2),同时T2‑T1>40℃;通过轻量化卡车侧裙板的结构设计以解决现有技术中存在的现有的主流卡车侧裙板主要采用铝合金材料,虽然具有导流、降低风阻的效果,但是重量大,安装成本较高技术问题。
