In view of the great friction and wear between the traveling vibration rubber plug,casing and rock,the aramid fiber cloth composite material was used to enhance the wear resistance of the traveling vibration rubber plug.Six kinds of sample fabrics with different warp and weft densities were weaved according to Bnierleys empirical formula.The effects of different warp and weft densities and different friction speeds on the wear resistance of aramid fiber cloth composites were tested by universal wear machine.The experimental results show that under certain friction speed,the higher the warp and weft density of the fabric,the better the wear resistance of aramid fiber cloth.Under the same warp and weft density of the fabric,within a certain friction speed range,the wear resistance of aramid fiber cloth is increased with the increase of friction speed.However,when the friction speed is too high,the wear resistance of aramid fiber cloth will decline
