In the dry sliding experiments of composites, friction coefficients decreased with the increase of load. Plastic deformation happened in the worn surface where Fe element was found, so PAM micro-fiber supported part of the load and prevented the further deformation. On the condition of high speed and high load, the worn surface of PAM1/nylon 6 composites was nearly melted and formed comparative uniform transfer on the surface of steel, which accounted for the rather low wear mass loss. The infrared analysis showed that the a small quantity of transition of crystal form from α into γ of nylon and its composites happened during the friction because of the high temperature and strong sheering strength.
