A04 Press processing of functionalised flat and tape substructures with a flanged section
Summary
The DediGrad subproject A04 develops manufacturing strategies for graded transition zones between continuous fibre-reinforced thermoplastics and thermoplastic bulk materials in press processing. Local grading is created deliberately by combining braiding processes, laser-based pre-treatment, and press forming. Experimental investigations are complemented by simulation-based analyses in order to understand the relationships between process parameters, microstructure, defects, and mechanical properties. The objective is to optimise the transition zone with respect to load-bearing capacity and lightweight potential. In this way, the project establishes the scientific foundations for the function-integrated press processing of graded flat and tape substructures.
001 Objectives

Graded Transition Zones

  • Enhancement of the lightweight potential of press-processed hybrid shell structures
  • Development of methods for creating graded transition zones
  • Investigation of the influence of local grading on further processing and transition-zone formation
  • Analysis of process–structure–property relationships by experiment and simulation
  • Demonstration of functionality using the EFS demonstrator
002 Scientific Questions

Material–Process Coupling

  • How can load-adapted local grading of continuous fibre-reinforced thermoplastics be achieved by braiding?
  • To what extent can fibres be lofted by targeted laser treatment without damage?
  • How does the grading of the preform affect subsequent press processing and the formation of the transition zone?
  • How can the relationships between mechanical properties, transition-zone phenomenology, and process parameters be used to enhance lightweight potential?
