Abstract

Abstract: The apparent characteristics of grooves on the friction surface and phase distribution of the C/C-SiC brake materials were analyzed. The causes and mechanism of grooves formation and its influence on braking performance were studied. The results show that when there are large hard spots on the friction surface of C/C-SiC brake materials, plough abrasion or extrusion spalling mechanism will occur, resulting in obvious trough groove or layered spalling groove. The braking torque of C/C-SiC brake materials with obvious grooves on the friction surface is higher than that of C/C-SiC brake materials with smooth friction surface.

Key words: C/C-SiC, friction surface, grooves, composites
