连续纤维增强加筋圆柱壳回转 3D 打印工艺及其轴压性能研究

In view of the shortcomings of the traditional forming process, combined with the advantages of additive manufacturing of low-cost and rapid manufacturing, the development status of 3D printing technology of reinforced cylindrical shell is analyzed, a reinforced cylindrical shell rotary 3D printing process method based on material extrusion technology is proposed, the rotary 3D printing process equipment is developed, and the grid structure and printing path for the reinforced cylindrical shell of continuous fiber reinforced composite materials are designed. The axial compressive properties of rectangular, triangular and diamond-shaped mesh ribs are explored under the same structural parameters, and the results showed that the axial compressive performance of diamond-shaped reinforced cylindrical shells was the best.
