Abstract

A circular needle loom comprises a bed plate for receiving a transport layer. Engagement members may be disposed proximate to the bed plate, such that the engagement members interface with a positional structure of the transport layer that is used to position and rotate the transport layer around the bed plate. The engagement members may be configured to rotate the transport layer around the bed plate until a predetermined number of fibers and/or layers are deposited on the transport layer and/or bed plate in order to create a needled preform.

First claim

What is claimed is:

1. A transport layer comprising:
a substantially annular shaped carbonized carbon fiber layer removably coupled to a substantially annular shaped scrim layer, wherein the substantially annular carbonized carbon fiber layer is sewn to the substantially annular shaped scrim layer,
wherein the substantially annular shaped carbonized carbon fiber layer substantially surrounds a first annular shaped scrim portion, and
wherein a second annular shaped scrim portion substantially surrounds the substantially annular shaped carbonized carbon fiber layer.

2. The transport layer of claim 1 , wherein the substantially annular shaped scrim layer comprises at least one of cotton, rayon, or polyester.

3. The transport layer of claim 2 , wherein the substantially annular shaped carbonized carbon fiber layer is at least one of sewn, needled, or bonded onto the substantially annular shaped scrim layer.

4. The transport layer of claim 1 , wherein the transport layer is configured to facilitate deploying carbon fibers on a circular needle loom.

5. The transport layer of claim 1 , wherein at least one of the first annular shaped scrim portion or the second annular shaped scrim portion is configured to couple with engagement members of a circular needle loom.

6. A circular needle loom comprising:
a transport layer, comprising:
a substantially annular shaped carbonized carbon fiber layer coupled to a substantially annular shaped scrim layer,
wherein the substantially annular shaped carbonized carbon fiber layer substantially surrounds a first annular shaped scrim portion,
wherein a second annular shaped scrim portion substantially surrounds the substantially annular shaped carbonized carbon fiber layer, and
wherein at least one of the first annular shaped scrim portion or the second annular shaped scrim portion is configured to couple with engagement members of the circular needle loom;

a stationary bed plate configured to receive the transport layer;
the engagement members disposed proximate the stationary bed plate, wherein the engagement members are configured to interface with at least one of the first annular shaped scrim portion or the second annular shaped scrim portion to facilitate rotating the transport layer around the stationary bed plate; and
a carbon fiber delivery system configured to lay down carbon fibers on the substantially annular shaped carbonized carbon fiber layer.

7. The circular needle loom of claim 6 , further comprising a needling zone proximate the stationary bed plate configured for needling of at least one of the transport layer or layers of the carbon fibers.

8. The circular needle loom of claim 6 , wherein the engagement members rotate the transport layer around the stationary bed plate until a predetermined number of layers of the carbon fibers are deposited and needled on top of the transport layer.

9. The circular needle loom of claim 6 , wherein the engagement members comprise a clamp to secure the transport layer to at least one of an inside support or an outside support.

10. The circular needle loom of claim 6 , wherein the engagement members comprise pins that engage at least one of the first annular shaped scrim portion or the second annular shaped scrim portion of the transport layer and rotate the transport layer on the stationary bed plate.

11. The circular needle loom of claim 6 , wherein the circular needle loom comprises at least one of:
an inside support disposed about an inside of the stationary bed plate; and
an outside support disposed about an outside of the stationary bed plate, wherein the engagement members are disposed proximate at least one of the inside support or the outside support.
