摘要：

In order to improve the tensile mechanics properties of 3D printing continuous carbon fiber reinforced composites, the influences of different filling paths on open-hole plates composite tensile properties were studied. The principal stress trajectory path planning method was used to print the main stress trajectory path filled open-hole plate test specimen,and the tensile properties were compared with zig-zag path filled open-hole plates and machined open-hole plates. The results show that, compared with machined open-hole plates, the tensile strength of principle stress trajectory path filled open-hole plates is 9.73% higher, and the elastic modulus is 25.58% higher. The principle stress trajectory path filled open-hole plate strain distribution before fracture is more uniform and the strain is smaller. © 2020, China Mechanical Engineering Magazine Office.
