Impact abrasive behavior of a graphite (T300)/polyamide composite was investigated by using a single pendulum scratching device. The results showed that the wear resistance of the composites decreased as the orientation angle beta between the fiber axis and the scratching direction increased; the friction coefficient decreased linearly as beta increased from 0 to 60 degrees, but increased as beta increased from 60 to 90 degrees. The scratching mechanism was analyzed by scanning electron microscopy, and the effect of the fiber orientation on wear and friction of the composite was explained in terms of ploughing, interface friction and breakage of fibers.
