Abstract: This article made a try on the prepration of abrasion-resistant composites by integrative RTM moulding. Wear testing of said composites was performed. Surface profiles of samples after wearing test were drawn by Phase Shift MicroXAM-3D. Granularity ansysis of hardness particle which was the main component of abrasion-resistant coating was conducted by laser granularity analyst. The inside microstructure of abrasion-resistant composites was observed by scanning electron microscope. The results demonstrated that the friction coefficient was coherent with ultimate indent depth, namely, the less the friction coefficient was, the less indent depth was. The use of abrasion-resistant composites in high speed conditions could be limited because resin was the matrix of abrasion-resistant coating.

Key words: composite, coat, friction coefficient, indent depth
