Stitched Preforms

Product Introduction

Stitching is a three-dimensional reinforcement technique that vertically binds multiple fabric or fibre layers by piercing yarns, primarily to enhance interlaminar strength and fatigue resistance. We operate a comprehensive range of stitching equipment and proven processes, compatible with carbon, basalt, aramid, quartz and other fibre systems, and adaptable to preforms of varied geometry—flat plates, cylinders, curved tubes and irregular edges.

Technical Advantage

Common stitching methods: through-thickness vertical stitching for thick panels and cylindrical structures; surface-lock stitching for edge encapsulation and curved-surface positioning. Stitch density can be adjusted to customer requirements, typically within 4–20 stitches per cm².
