Sleeper and preparation method thereof
The invention discloses a sleeper and a preparation method thereof.The sleeper comprises a sleeper core material and a sleeper base material, the sleeper core material is located at the position, where spikes are installed, in the sleeper, and the sleeper core material is located in the sleeper base material; the length of the sleeper core material is the same as that of the sleeper, and the sleeper core material is parallel to the sleeper; the density of the sleeper core material is greater than or equal to that of the sleeper; the sleeper core material comprises first fibers and first resin, the sleeper base material comprises second fibers and second resin, and the arrangement direction of the first fibers and the arrangement direction of the second fibers are parallel to the length direction of the sleeper. The number of the glass fibers needing to be impregnated in the impregnation stage is controlled by increasing the sleeper core materials, so that uneven rubbing is avoided, one-time large-thickness integral forming without secondary flat plate bonding can be achieved, and the fiber content of the cross section of a product and the density of the product can be controlled within the required range.
本申请公开了一种轨枕及其制备方法，所述轨枕包括轨枕芯材和轨枕基材，所述轨枕芯材位于所述轨枕中安装道钉的位置，所述轨枕芯材位于所述轨枕基材内部；所述轨枕芯材的长度与所述轨枕的长度相同并与所述轨枕平行；所述轨枕芯材的密度大于或等于所述轨枕；所述轨枕芯材中包括第一纤维和第一树脂，所述轨枕基材包括第二纤维和第二树脂，所述第一纤维和所述第二纤维的排布方向与所述轨枕的长度方向平行。本申请采用增加轨枕芯材的方式，来控制浸渍阶段需要浸渍的玻璃纤维数量，从而避免揉搓不均，又能实现非二次平板粘接而一次大厚度整体成型，且产品横截面纤维含量和产品密度可控制在要求范围之内。
