The orientation of the polymer molecules can be increased by a subsequent drawing process heated to a temperature above the glass transition and drawn with a series of rollers. The purpose of the draw process is to convert relatively weak sheets to sheets with greater molecular orientation and the resulting greater strength. Friction and wear properties of MoS2-filled drawn nylon 6 sheets were investigated for anti-wear property. Drawing MoS2-filled nylon 6 sheet was made by single-stage uniaxial drawing process. Friction coefficient of drawing MoS2-filled nylon sheet was measured on a dry condition. The result showed that the friction coefficient was slightly decreased in drawing process. It indicated that anti-wear property of the MoS2-filled nylon 6 sheet had not difference in wear by drawing process. In the tribological point of view, friction coefficient of the drawing MoS2-nylon 6 sheets was approximately 0.15, and then friction coefficient of the drawing MoS2-nylon 6 sheet was stable curve for 120min. But friction coefficient of non-drawing samples shown more smooth line curve after 30 min. Volume loss of drawing MoS2-filled nylon 6 sheet was lower from that of pure nylon. As a result of this investigation, we remarked that wear-resistant of the MoS2-filled nylon 6 sheet has made progress by drawing process. |
