| Abstract | The addition of less than 20 wt% of approximate 1 micron barium sulfate (BaSO4)into polyurethane (PU) composites modified by bishydroxyalkyl-terminated polydimethyl- siloxane (PDMSBH) resulted in increases in mechanical strength and thermal conduc- tivity and, at the same time, resulted in improvements in the friction and wear properties of the polyurethane composites. These polyurethane compositeswere suitable formarine use for bearings at high load under dry friction and at fast sliding speed under wa- ter lubrication. Characterization with Fourier transform infrared (FTIR) spectroscopy, thermogravimetry analysis (TGA), scanning electron microscope (SEM), and an MRH- 3 ring-on-block wear tester indicated that the addition of BaSO4 disrupts the organic phase separation in the polyurethane, resulting in better tribological properties, but there is no special chemical reaction between the particles and polyurethane. Adding too much BaSO4 resulted in higher wear rate because of inorganic–organic phase separation. |
