In order to improve the performance of the quadruped robot bionic leg and make its leg structure meet the high load-bearing and lightweight requirements

a hybrid reinforced 3D printing technology with continuous carbon fiber (CCF) as the reinforcing material and short-cut carbon fiber reinforced nylon as the matrix material is proposed

and the tensile properties of the carbon fiber composite are verified by using the sample tension. The hybrid reinforced 3D printing with continuous and short-cut carbon fibers was used to manufacture the quadruped robot bionic leg

and the static simulation was conducted for four common working conditions of the quadruped robot. The load capacity in the 30° outreach condition was increased by 3.14% and the deformation was reduced by 43.05%

and the weight was reduced by 18.83%

which verified the possibility of replacing the traditional aluminum alloy with continuous carbon fiber reinforced material.
