Abstract:

This study focuses on the distribution of flow field inside the airflow spreader and the force on carbon fiber bundles in the flow field under different fractal flow path conditions. The discrete element Method was used to model the spreading behavior of the thousands of filaments in the flow field. The characteristics of the flow field and the motion of the fiber discrete elements were modeled. By comparing the magnitudes of the forces on the fiber discrete elements to the magnitudes of the fluid resistance, equations of motion for the fiber discrete elements were finally established. With the particle tracking module of COMSOL, the fluid-fiber discrete element interaction was simulated numerically by setting the corresponding boundary conditions with the spreading process. The effect of the position of the fractal flow paths on the motion characteristics of the carbon fiber bundle was investigated. The results show that with the increase of the distance between the fractal flow paths, the length of the fiber spreading area in the flow field increases, which is beneficial for fiber spreading. It is found that shortening the distance between the rightmost fractal flow path to the fiber exit and reducing the length of the fiber spreading region help the fiber bundle spreading.
