Abstract
Disclosed is a cruciform-shaped reinforcing structure with at least two arms of intersecting C-Beams having continuous warp fiber reinforcement across the length of each arm.
Claims35
A method of forming a woven preform, comprising:
- weaving a first fabric over a second fabric in a first portion of the woven preform, the first and second fabrics each including warp fibers interwoven with weft fibers;
- interweaving warp fibers of the first fabric with warp fibers of the second fabric at a crossover portion of the woven preform such that after the crossover portion the first fabric is woven under the second fabric in a second portion of the woven preform;
- wherein the warp fibers in the first and second fabrics are continuous across the crossover portion.
A woven preform, comprising:
- a first fabric of warp fibers interwoven with weft fibers;
- a second fabric of warp fibers interwoven with weft fibers,
- wherein the warp fibers of the first fabric are interwoven with the warp fibers of the second fabric at a crossover portion such that the warp fibers in the first fabric and the warp fibers in the second fabric are continuous across the crossover portion,
- wherein the first fabric and the second fabric elsewhere from the crossover portion are not interwoven with one another.

A method of forming a woven preform, comprising:
- weaving at least three woven fabrics including warp fibers interwoven with weft fibers, each woven fabric having a first fabric woven over a second fabric in a first portion of the woven preform;
- interweaving each of the at least three fabrics with at least one remaining woven fabric at a respective crossover portion, such that there are at least two crossover portions in each woven fabric;
- wherein after each crossover portion of the at least three woven fabrics, an intersecting fabric woven over another fabric is woven under the another woven fabric,
- wherein the warp fibers in the intersecting fabrics are continuous across each crossover portion.
1 more element
A woven preform, comprising:
- at least three woven fabrics having warp fibers interwoven with weft fibers, each woven fabric having a first fabric woven over a second fabric in a first portion of the woven preform;
- wherein each of the at least three woven fabrics is interwoven with at least one remaining woven fabric at a respective crossover portion, such that there are at least two crossover portions in each woven fabric;
- wherein after each crossover portion of the at least three woven fabrics, an intersecting fabric woven over another fabric is woven under the another woven fabric,
- wherein the warp fibers in the intersecting fabrics are continuous across each crossover portion.
