Abstract
A friction system comprising at least two frictionally coupled elements produced of refractory composite materials, wherein one of the friction elements is a carbon-carbon composite material whereas the second friction element is a composite material constituted of a fibrous reinforcement in which the fibers are selected from carbon fibers and silicon carbide fibers, and of a two-phased matrix of which the principal phase is constituted by silicon carbide.
Claims7
A friction system, comprising:
- a first friction element having a first confronting surface, and wherein said first friction element is made of a carbon-carbon composite material;
- a second friction element having a second confronting surface, and wherein said second friction element is made of a multiphase composite material comprised of a fibrous reinforcement having fibers selected from the group consisting of carbon fibers and silicon carbide fibers, and a matrix having a principal phase which forms a major part of said matrix and is comprised of silicon carbide, and a secondary phase which forms a minor part of said matrix and is comprised of a refractory material selected from the group consisting of titanium carbide, zirconium carbide, tantalum carbide, boron carbide, elemental boron, silicon nitride, boron nitride and pyrolytic carbon, and
- wherein said first confronting surface of said first friction element confronts and is frictionally coupled to said second confronting surface of said second friction element.
