Composites of micro- crystal muscovite / UHMWPE( ultrahigh molecular weight polyethylene)wear prepared by pressing-sintering,the mechanical properties and erosion tests of the composites were carried out.The erosion resistance of the composites materials with the filling amount of 5% was the best,and the erosion rate was about 30% lower than that of pure UHMWPE,and only about 0.08 times of 45# steel under the same condition. According to correlation analysis,the product of the impact toughness and the dynam...
