C/C-SiC Composites for Advanced Friction Systems
TLDR
Ceramic Matrix Composites (CMC) as discussed by the authors is a type of composite material based on carbon fibres and silicon carbide matrices, which have superior tribological properties in comparison to grey cast iron or carbon/carbon.Abstract:
Ceramic Matrix Composites (CMC), based on reinforcements of carbon fibres and matrices of silicon carbide, show superior tribological properties in comparison to grey cast iron or carbon/carbon. In combination with their low density, high thermal shock resistance and good abrasive resistance, these Si-infiltrated carbon/carbon materials, called C/SiC or C/C-SiC composites, are promising candidates for advanced friction systems. Generally, the carbon fibres lead to an improved damage tolerance in comparison to monolithic SiC, whereas the silicon carbide matrix improves the wear resistance compared to carbon/carbon. In combination with new design approaches cost-efficient manufacturing processes have been developed and have lead to successfully tested prototypes of brake pads and disks, especially for passenger cars and emergency brake systems.read more

Cost Effective Processing of CMC Composites by Melt Infiltration (LSI-Process)
TL;DR: In this article, a cost efficient manufacturing route has been developed by DLR based on the infiltration of a reactive fluid phase into porous carbon fiber preforms, where Molten silicon is used as the reactive fluid which replaces the initial pore volume of the preform and reacts subsequently with the carbon matrix to form silicon carbide.

Method of manufacturing a friction element
TL;DR: In this article, a method of manufacturing a friction element designed for frictional contact with a body and for use, in particular, in brakes or clutches was proposed. But the method called for a porous carbon block to be produced which approximately matched the shape of the end of the abrasion unit, liquid silicon was infiltrated into the pores of the carbon block and the block was ceramized by initiating a chemical reaction to form silicon carbide.
