Abstract: In the process of composite winding, the frictional behavior between the fiber and mandrel can lead to slip. The condition of stable winding is that the maximum slippage coefficient of the designed fiber trajectory is less than or equal to the friction coefficient between the fiber and the mandrel, so the friction coefficient between the carbon fiber and the mandrel is an important basis in the design of the fiber trajectories. Friction experiments using a sled based on principle of plane friction are performed in order to characterization the friction coefficient. The influence patterns of normal force, velocity, roughness, resin viscosity, contact material, the angle of fiber and the direction of motion and the type of fibers on the coefficient of friction were obtained. The results show with the increase of normal force or the decrease in velocity and roughness will lead to the decrease in the coefficient of friction. A change of viscosity and fiber orientation have a double effect on the coefficient of friction, which shows different effects with the change in normal force and velocity, and different contact materials and fiber types will lead to different coefficients of friction due to the differences in the surface conditions.
