WOVEN STRUCTURE AND METHOD OF MANUFACTURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240035210 titled 'WOVEN STRUCTURE AND METHOD OF MANUFACTURE
Simplified Explanation
The patent application describes a method for manufacturing a composite component using a multi-layer woven preform made from warp and weft tows of fiber-reinforcement material. The woven preform consists of a multi-layer weave with several weft tow layers and laterally-adjacent stacks along the longitudinal direction. The primary portion of the weave extends along the woven preform and has edge regions on each side.
In the edge regions, the multi-layer weave defines the edge and consists of binding stacks where warp tows are interlaced to bind multiple weft tow layers together. The weave property in the binding stacks differs to reduce the thickness of the edge region towards the respective lateral side.

Original Abstract Submitted
a method for manufacturing a composite component, including: weaving a multi-layer woven preform from warp and weft tows of fibre-reinforcement material, the woven preform includes: multi-layer weave including: plurality of weft tow layers; plurality of laterally-adjacent stacks extending along the longitudinal direction, primary portion having longitudinal extent along woven preform, the primary portion having one or more edge regions each defining respective lateral side of primary portion; wherein for the or each edge region: the multi-layer weave defines at least the edge region; plurality of stacks in the edge region are binding stacks in which one or more warp tows are interlaced to bind a respective plurality of weft tow layers; weave property differs between binding stacks in the edge region to reduce a thickness of the edge region towards respective lateral side. also disclosed herein is a woven structure, formed by warp and weft tows of fibre reinforcement material.
