## Abstract

The invention is directed to a fiber braid having at least a first fiber extending spirally along an imaginary axis such that the first fiber forms a predetermined angle with the imaginary axis and at least a second fiber interlaced with the first fiber and extending spirally and coaxially with the first fiber such that the second fiber and the first fiber form a tubular network, with the imaginary axis serving as the axis. At least a third fiber is added to the tubular network so that it extends in a direction parallel to the axis of the tubular network, and is interlaced through a selected number of openings in the tubular network.

## Claims

### Claim 1

A fiber braid comprising:
at least a first fiber extending spirally along an imaginary axis such that said first fiber forms an angle with said imaginary axis;
at least a second fiber interlaced with said first fiber and extending spirally and coaxially with said first fiber such that said second fiber and said first fiber form a tubular network, with said imaginary axis serving as an axis of said tubular network, said tubular network comprising openings formed by interlacing the first fiber and the second fiber; and
at least a third fiber which is oriented in a direction parallel to said axis of said tubular network, wherein said third fiber is interlaced through the openings in said tubular network;
wherein said tubular network is united with a plurality of third fibers which are interlaced with said first fiber and said second fiber such that each said third fiber of said plurality of fibers is interlaced in the openings in the same manner as another said third fiber on an opposite side of said axis of said tubular network.

### Claim 2 (depends on 1)

The fiber braid as defined in claim 1, wherein said third fiber is interlaced with said first fiber and said second fiber so as to bypass one or more of said openings.
