Embroidering Reinforcement Fiber Rovings onto Textile Substrates for 3D Preforms

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method for producing complex 3D preforms by using a stitchable textile surface as the base layer. Strengthening fiber strands (rovings) are embroidered onto this textile using a blind stitch technique with a curved needle, without fully penetrating the textile. The base layer can be made from either knit or non-knit textile materials.

Patent Abstract

The invention relates to a method for manufacturing complex 3D preforms using an embroiderable textile fabric as a base layer, wherein the textile fabric is in the form of a mesh-forming or non-mesh-forming textile semi-finished product. By means of a blind stitch type, strands of reinforcement fibers (rovings) are embroidered onto the textile fabric with a curved needle, wherein the textile fabric is not completely pierced.
