摘要

The effect of inorganic fillers on the friction and wear behavior of frictional material based poly(m-phenylene isophthalamide) (PMIA) is investigated. The polymer composites are prepared by compression molding. The friction and wear of PMLA composites are investigated on a block-on-ring machine by running the PMIA composite block against plain carbon steel. The morphologies of the worn surface of PMIA composite and the ring counterface are examined by using electron probe microanaly-sis. It is found that copper compounds including CuCi, CuCl2, Cu2O, and CuO filled PMLA exhibit considerably higher friction coefficient than unfilled PMIA, while the wear rate of those composites decrease. Especially, CuCI is the optimal filler in the copper compounds investigated above. The filled PMJA composite containing CuCI, graphite, and short carbon fiber shows the best properties for frictional material. The friction coeffi-cient of CuCl—PMIA composite is higher than that of unfilled PMIA because of the abrasive action of CuCl particle. It is probably the smoother surface of counterpart ring and composite block that resulted in the lower wear rate and friction coefficient of PMJA composite.
