We investigated the effect of carbon fiber (CF) on the capillary flow behavior of high-density polyethylene (PE). The presence of CF was found to have much great effect on reducing of the die swell of PE. CF could prevent the helical distortion of PE. The helical distortion of PE also changed to the sharkskin failure by adding CF. The extrusion behavior can be controlled by the addition of a small amount of CF.
