B01 Adaptive production of components with locally definable adjustment of the fibre architecture
Summary
The DediGrad subproject B01 investigates adaptive manufacturing strategies for the targeted adjustment of fibre architecture in graded components. To this end, additive manufacturing is linked with injection-moulding-analogue processes in order to represent locally definable fibre orientations, fibre contents, and continuous reinforcements both experimentally and numerically. The objective is to explore intrinsic and extrinsic grading strategies, derive suitable transfer methods between additive manufacturing and injection moulding, and develop a systematic understanding of the resulting structure–property relationships. In this way, the subproject establishes a flexible development platform for the targeted design of load-adapted components and their manufacturing parameters.
001 Objectives

Controled Fibre Architectures

  • Development of an additive production system with locally adjustable fibre architecture
  • Investigation of intrinsic and extrinsic grading strategies
  • Research into the transferability of properties from additively manufactured parts to injection-moulding-analogue processes
  • Analysis of structural mechanisms under static and dynamic loading
  • Establishment of a development platform for the CRC/TRR
002 Scientific Questions

Cross-Process Grading

  • How can graded structural-mechanical mechanisms be characterised under static and dynamic loading?
  • How can additive manufacturing be designed for precise control of fibre architecture?
  • How can strength gradients be modulated by means of extrinsic grading strategies?
  • Which transfer functions are suitable for describing component properties between additive manufacturing and injection moulding?
