Abstract

The present disclosure provides a fibrous preform, comprising an annulus having at least one of an outer diameter portion or an inner diameter portion, the outer diameter portion extending radially inward from an outer diameter of the fibrous preform and the inner diameter portion extending radially outward from an inner diameter of the fibrous preform. In various embodiments, the fibrous preform further comprises a medial diameter portion disposed between the outer diameter and the inner diameter, wherein the medial diameter portion comprises a first needling profile, and the at least one of the outer diameter portion or the inner diameter portion comprises a second needling profile. In various embodiments, the first needling profile is less than the second needling profile.

First claim

What is claimed is:

1. A brake disk, comprising:
an annular disk having at least one of a rotor lug disposed on an outer diameter of the brake disk or a stator lug disposed on an inner diameter of the brake disk, and at least one of an outer diameter portion extending radially inward from the outer diameter or an inner diameter portion extending radially outward from the inner diameter;
a medial diameter portion disposed between the outer diameter and the inner diameter; and
a heat affected zone disposed in the medial diameter portion, the heat affected zone configured to expand in response to an increase in temperature following a rejected take off,
wherein the medial diameter portion comprises a first needling profile, and the at least one of the outer diameter portion or the inner diameter portion comprises a second needling profile,
wherein the first needling profile is less than the second needling profile,
wherein the rotor lug comprises the second needling profile, and
wherein the heat affected zone comprises a third needling profile, the third needling profile being less than the first needling profile.

2. The brake disk of claim 1 , further comprising:
an inner portion disposed between a first planar portion and a second planar portion, the first planar portion being disposed at a first axial end of the brake disk and adjacent to a first planar face of the brake disk and the second planar portion being disposed at a second axial end of the brake disk and adjacent to a second planar face of the brake disk;
wherein the inner portion comprises a fourth needling profile, the fourth needling profile being greater than the first needling profile.

3. A brake disk, comprising:
an annular disk having at least one of a rotor lug disposed on an outer diameter of the brake disk or a stator lug disposed on an inner diameter of the brake disk, and at least one of an outer diameter portion extending radially inward from the outer diameter or an inner diameter portion extending radially outward from the inner diameter;
a medial diameter portion disposed between the outer diameter and the inner diameter; and
a heat affected zone disposed in the medial diameter portion, the heat affected zone configured to expand in response to an increase in temperature following a rejected take off,
wherein the medial diameter portion comprises a first needling profile, and the at least one of the outer diameter portion or the inner diameter portion comprises a second needling profile,
wherein the first needling profile is less than the second needling profile,
wherein the stator lug comprises the second needling profile,
wherein the heat affected zone comprises a third needling profile, the third needling profile being less than the first needling profile.
