## Abstract

In various embodiments, the present disclosure relates generally to a method for needling a spiral textile to create a needled preform, the method comprising receiving the spiral textile on a bed plate of a circular needle loom, engaging a positional structure of the spiral textile, rotating the spiral textile around the circular needle loom, depositing a predetermined number of layers of the spiral textile on the bed plate, and needling the spiral textile to create the needled preform. Moreover, the present disclosure also provides, in various embodiments, a method for creating a circular needled preform from a spiral textile, comprising attaching sacrificial fibers to at least one of the weft tow and the plurality of warp tows proximate at least one of the inside diameter and the outside diameter, and engaging the sacrificial fibers with an engagement mechanism on a circular needle loom.

## Claims

### Claim 1

A method for needling a spiral textile to create a needled preform, the method comprising: receiving the spiral textile on a bed plate of a circular needle loom;
engaging a positional structure of the spiral textile;
rotating the spiral textile around the circular needle loom;
depositing a predetermined number of layers of the spiral textile on the bed plate; and
needling the spiral textile to create the needled preform.

### Claim 2

A method for creating a circular needled preform from a spiral textile, comprising:
weaving a weft tow from an inside diameter to an outside diameter of the spiral textile into a plurality of warp tows spaced between the inside diameter and the outside diameter;
attaching sacrificial fibers to at least one of the weft tow and the plurality of warp tows proximate at least one of the inside diameter and the outside diameter;
engaging the sacrificial fibers with an engagement mechanism on a circular needle loom;
moving the spiral textile on the circular needle loom to deploy a predetermined number of layers of the spiral textile on the circular needle loom; and
removing at least a portion of the sacrificial fibers after needling the spiral textile.

### Claim 3 (depends on 1)

The method of claim 1, wherein the positional structure is a sacrificial structure.

### Claim 4 (depends on 1)

The method of claim 1, wherein the positional structure comprises a sacrificial edge.

### Claim 5 (depends on 4)

The method of claim 4, wherein the positional structure further comprises a fiber loop.

### Claim 6 (depends on 1)

The method of claim 1, wherein the engaging comprises engaging the positional structure with engagement members.

### Claim 7 (depends on 1)

The method of claim 1, further comprising removing the positional structure from the spiral textile.

### Claim 8 (depends on 1)

The method of claim 1, wherein the positional structure is located on at least one of an inner diameter and an outer diameter of the spiral textile.
