Fabrication of Polyurethane‐Based Composites Used in Water‐Lubricated Bearings

“…1,2 Undoubtedly, excellent comprehensive performance is necessary as the composite materials used in WLB, including excellent antifriction and wear properties, high tensile strength and elongation at break, extremely hydrolysis resistance, low water swelling, and suitable elastic modulus. [17][18][19][20] Relative systematic studies on PU have been carried out to modify or fill PU as coatings and medical applications but not for elastomers as tribological materials. It has been successfully employed in an increasing variety of applications and became one of the most famous polymeric materials because of its outstanding properties, including excellent tensile strength, tear strength, oil resistance, load bearing ability, solvent resistance, and abrasion resistance.…”

“…This is the main reason for limiting its use in the industry. [17][18][19][20] Relative systematic studies on PU have been carried out to modify or fill PU as coatings and medical applications but not for elastomers as tribological materials. [21][22][23][24][25][26] Many approaches have been adopted for improving the properties of many kinds of PU coatings by chemical modification or fiber reinforcement or filled nanoparticles.…”

“…However, the abrasion resistance of PU elastomer will be dramatically reduced once the sliding friction is generated under high frequency, due to the sharp increase in interior heat generated on the friction surface of PU. This is the main reason for limiting its use in the industry …”
