3D printing grating reinforced cement-based composite material and preparation method thereof
The invention relates to a 3D printing grid reinforced cement-based composite material and a preparation method, the composite material comprises an RO grid structure and a cement-based material formed by mixing standard sand, water and cement, the composite material is characterized in that the RO grid structure takes PA6 as a raw material, grids are distributed in the cement-based material in the form of a skeleton or a reinforcement body, and the RO grid structure is formed by mixing the standard sand, the water and the cement. A unit cell grating of the RO grating structure is constructed by rhombic octahedral units, the sizes of center lines of the unit cell grating are equal in x, y and z directions, and the unit cell grating is geometrically symmetric around three vertical planes where the center points of the unit cell grating intersect. The method is simple in implementation step and high in operability, and has a good ductility/toughness enhancing effect.
一种3D打印格栅增强水泥基复合材料及制备方法，所述复合材料包括RO格栅结构和以标准砂、水、水泥拌制而成的水泥基材料，其特征在于，所述RO格栅结构以PA6为原材料，格栅以骨架或增强体的形式分布在水泥基材料中，所述RO格栅结构的单胞格栅由菱形八面体单元构建的，所述单胞格栅的中心线尺寸在x、y、z方向上相等，并且在其中心点相交的三个垂直面周围呈几何对称。该方法实施步骤简单，可操作性高，并具备良好的增强延性/韧性效果。
