Benefits of technology

The patent describes a method for making a textile material that can be molded to have a complex curvature. This involves creating a single piece of textile material that has an optimal pattern for certain parameters. This invention ensures that the textile material can be easily molded while maintaining its shape and quality.

Problems solved by technology

Existing textile are unable to produce flat reinforcement fabrics that are thick, net-shape, drapable onto doubly-curved surfaces, and made from continuous yarns oriented in a way to promote coverage, resin flow and / or structural stiffness.

Abstract

Described is a method of forming a textile perform for a mold having a complex curvature.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims benefit of priority to U.S. Provisional Patent Application No. 61 / 409,610 filed Nov. 3, 2010 which is incorporated by reference in its entirety.BACKGROUND[0002]1. Field of the Invention[0003]The present invention relates to methods of producing reinforcement fabrics for polymer-matrix composite (PMC) materials, especially PMC materials with high volume fractions of structural fibres produced by impregnation of the reinforcement with a curable or otherwise solidified polymer.[0004]2. Related Art[0005]Existing textile are unable to produce flat reinforcement fabrics that are thick, net-shape, drapable onto doubly-curved surfaces, and made from continuous yarns oriented in a way to promote coverage, resin flow and / or structural stiffness.SUMMARY[0006]According to one broad aspect, the present invention provides a method comprising the following step: (a) forming a textile preform for a mold having a complex curvature,...
