Abstract
A brake disk (10) includes an annular core (12, 60, 82) formed from a plurality of non-annular pieces (40, 66, 68, 84), a first friction disk (14) mounted on a first side of the annular core (12, 60, 82), a second friction disk (14) mounted on a second side of the core (12, 60, 82) opposite from the first friction disk (14), and at least one fastener (58) connecting the first and second friction disks (14, 14) to the core (12, 60, 82). Also a method of assembling a brake disk from a core and friction elements.
Claims17
A method comprising:
- determining a required shape of a discrete, annular, carbon-carbon composite article;
- forming a plurality of non-annular preforms configured to be assembled into an annular shape;
- densifying the plurality of non-annular preforms to form a plurality of densified non-annular preforms;
- and
- assembling the plurality of densified non-annular preforms to form the discrete, annular, carbon-carbon composite article.
A brake disk comprising:
- an annular core comprising an annular first element having a first thickness and an inner or an outer periphery comprising a plurality of protrusions and an annular second element comprising a plurality of notches complementary to the protrusions, wherein the annular second element comprises a plurality of non-annular elements;
- a first friction disk mounted on a first side of the annular core;
- a second friction disk mounted on a second side of the annular core opposite from the first friction disk;
- and
- at least one fastener connecting the first and second friction disks to the annular core.
A method of assembling a carbon-carbon composite brake disk, the method comprising:
- forming a plurality of non-annular preforms comprising notches and configured to be assembled into an annular shape;
- densifying the plurality of non-annular preforms to form a plurality of densified non-annular elements;
- placing a first annular friction disk in a restraint fixture;
- placing on the first annular friction disk in the restraint fixture an annular core element including a plurality of protrusions having a shape along an inner or an outer periphery of the annular core element;
- placing the plurality of densified non-annular elements into the restraint fixture with the notches engaging the protrusions to form the annular shape;
- placing a second annular friction disk on the annular core element;
- and
- connecting the first and second friction disks.
