Abstract

A water entanglement system having a first rotatable surface comprises a first water jet which may be configured to water-entangle a preform in situ. The water-entanglement system may comprise a second rotatable surface disposed proximate the first rotatable surface. The second rotatable surface may comprise a second water jet configured to water-entangle the preform in situ. The first rotatable surface may be oriented substantially parallel to the second rotatable surface.

First claim

The invention claimed is:

1. A water-entanglement process comprising:
feeding a substantially continuous spiral fabric to a space defined by a first rotatable surface comprising a first water jet and a second rotatable surface comprising a second water jet;
growing a preform based on the substantially continuous spiral fabric; and
imparting water to a surface of the preform from at least one of the first water jet or the second water jet, wherein the water entangles the preform.

2. The process of claim 1 , further comprising receiving the substantially continuous spiral fabric from a first fabric source and a second fabric source.

3. The process of claim 2 , wherein the first fabric source is at least one of a carbon fiber spiral manufacturing source or a helical fabric manufacturing source.

4. The process of claim 2 , wherein the second fabric source is at least one of a carbon fiber spiral manufacturing source or a helical fabric manufacturing source.

5. The process of claim 1 , wherein the imparting occurs during formation of the preform.

6. The process of claim 1 , wherein during the imparting, water entangles the preform in situ.
