AI Technical Summary

Technical Problem

Existing fastening systems for textiles to metal profiles or other components are complicated and difficult to reproduce, leading to inconsistent results.

Method used

A material composite is created by applying piping to a substrate using additive manufacturing, allowing for high manufacturing accuracy and flexibility, with varying layer widths, lengths, and thicknesses, and incorporating elastic materials like silicones or thermoplastics, which can be integrated with grooves or webs for secure attachment.

Benefits of technology

The solution provides a flexible and efficient fastening system that can accommodate various geometric requirements, ensuring secure and reproducible attachment of textiles or other materials to components, enhancing manufacturing precision and ease of application.

Abstract

The invention relates to a composite material comprising a substrate and an applied piping, wherein the piping is produced in multiple layers using an additive manufacturing process. The composite material can be frictionally and / or positively connected to a component in a fastening system in which the piping of the composite material interacts with at least one groove or at least one web of the component.
