Development of metal textile composites with improved adhesion behavior by structuring of metal surfaces with an anodic TIG arc process or a CW laser process

1 Development of metal textile composites with improved adhesion behavior by structuring of metal surfaces with an anodic TIG arc process or a CW laser process MeTexCom2 Project duration: 24 months German partner 1 st April st March 2018 Czech partner 1 st January st December 2017 Project number: IGF 157 EBR 1

2 Consortium MeTexCom2

3 Background and goal of the project Main objectives of the project: Development of novel polymer metal composites with superior adhesion behavior between a metal sheet with a pretreated surface and a textile surface Creation of extreme lightweight structures with interesting acoustic features (sound absorption) and thermal insulating behavior or armoring behavior for applications in automotive and construction sector To reach the required properties of the final products the following methods will be used: TIG arc and CW laser texturing of metal surfaces, Preparation of acoustic and thermal insulating nonwovens, Preparation of textile composites based on armoring textiles with polymeric interface, Joining by heat pressing and lamination methods.

One important project aim is to eliminate the application of any adhesives and/or connecting materials and at the same time

4 Background and goal of the project Application of the electrical arc or cw laser treatment to create a micro/nanostructure on the metal surface and to improve the adhesion behavior between metal and textile component significantly. One important project aim is to eliminate the application of any adhesives and/or connecting materials and at the same time to ensure improved adhesion behavior. Composite materials will be composed of nonwovens, woven armouring textiles and thermoplastic polymers.

5 Background and goal of the project Micro structure on metal sheet surfaces after treatment with a cw single mode laser Micro structure on metal sheet surfaces after treatment with an anodic poled TIG process
