Abstract
A multimaterial disk for high-energy braking comprises an assembly of various flanges. They comprise, in succession, a central flange and on either side of the central flange thermal barriers and outer flanges made up of a substrate faced on one side with a ceramic or cermet type facing.
Claims21
A multimaterial disk for high-energy braking comprising an assembly of flanges and including in succession a central flange, thermal barriers on either side of said central flange, and outer flanges each comprising a substrate having an inner side disposed on a corresponding one of said thermal barriers and an outer side carrying a facing, wherein said thermal barriers are made from composite materials comprising a mixture of oxide ceramic fibers and an organic binder.
A multimaterial disk for high-energy braking comprising an assembly of flanges and including in succession a central flange, thermal barriers on either side of said central flange, and outer flanges each comprising a substrate having an inner side disposed on a corresponding one of said thermal barriers and an outer side carrying a facing, wherein said thermal barriers are made from composite materials comprising a mixture of alumina fibers and an organic binder.
A multimaterial disk for high-energy braking comprising an assembly of flanges and including in succession a central flange, thermal barriers on either side of said central flange, and outer flanges each comprising a substrate having an inner side disposed on a corresponding one of said thermal barriers and an outer side carrying a facing, wherein said thermal barriers are flanges made from a solid sintered ceramic material including one of zirconia and a thermally insulative ceramic material.
