Abstract. The model of acoustic emission signal formation during friction and wearing of composite materials surfaces was examined. The forms of acoustic emission resultant signals were shown. The regularities of parameters change in acoustic emission resultant signals with an increasing rotation speed were determined on results of modeling. The good agreement between theoretical and experimental results of acoustic emission signals registered in friction of composite materials surface layers was shown.
