Abstract
This study explores material modification utilizing molybdenum disulfide and glass fiber as lubricating and reinforcing modified materials respectively. The specimens underwent tests for mechanical-physical properties, oil storage capacity and frictional characteristics. The differential analysis identified the optimal mechanical-physical properties of the porous composite PI material at a molding pressure of 192 MPa, molding temperature of 330°C, 9% of AC foaming agent content, 8% of molybdenum disulfide content, and 20% of glass fiber content. The wear coefficient increased with load and decreased with rotational speed, indicating the suitability of this porous composite oil-retaining PI material for medium-high-speed and low-load frictional conditions.
