Description

The Materials and Processes Section provides functional support to ESA projects and carries out technological research (R&D) in the area of materials and associated manufacturing processes.

Field(s) of activities/research

The materials and processes used for space hardware manufacturing are confronted with very peculiar challenges and limitations: the omnipresent need for low mass must be met while also guaranteeing very high performance and reliability of the final product with no repair or maintenance option. Often small and complex geometries for operating in highly demanding mission environments are necessary. The industrial transition towards Industry 4.0 is introducing smart production capabilities through digitalisation and automation, enabling agility to react quickly to market needs and allowing unprecedented design solutions (e.g. additive manufacturing) as well as optimisation of cost, performance and time-to-market. In order not to compromise this agility through extensive and resource intensive testing and qualification, predictive modelling approaches are necessary, ultimately leading to a full digital twin of the manufacturing process and Integrated Computational Materials Engineering (ICME) solutions for performance prediction.

The objective of this research activity is to develop ICME solutions for space-relevant manufacturing processes (e.g. powder bed additive manufacturing) to fully understand the process-structure-performance relationship.

The ICME approach involves linking materials models at a multitude of scales, including:

  • nanoscale at atomistic level such as molecular dynamics
  • microscale such as phase formation and dislocations
  • mesoscale at the level of repeating unit cells such as mechanical strength, fracture energy
  • macroscale at continuum level such as mechanical performance and durability

The different scale models should be dynamically interactive and need to consider all manufacturing steps including possible post-processing as well as time and temperature effects after assembly during ground and orbital phases. Possible processes to be studied include powder or wire-based additive manufacturing, welding, soldering and composite technologies. The conclusion of this activity is expected to establish a foundation for predictive materials performance modelling, supporting the space industry’s transition towards agile manufacturing technologies.

  • multi-scale materials modelling from nano- to macroscale
  • progressive damage analysis
  • process health management
  • experimental model verification
