De-risk assessment: LESSON - LargE Scale Struts prOductioN

The production process of full-CFRP struts, was before only suitable for low volume production rates (~10 struts/month) and including worker safety critical processes. This approach had to be reviewed and changed to enable production rates >100/month and improve worker safety. The activity focused on the:

SPACE STRUCTURES GMBH
Demonstration of Thermoplastic Composites
The following activities shall be accomplished:
 
  • State of the art review and establishment of application rang.
 
  • Selection of demonstration application for replacement of existing technologies. The application to be selected shall be a qualified part/subcomponent on an existing, qualified, space product.
 
  • Design and materials trade-off, including fibre and resin system, and preliminary design.

    Development of modular multifunctional structure panel prototype
    The activity shall be performed with the following steps:
     
    • Identification of a relevant existing structural panel with various subsystem functionalities attached, e.g. thermal control, AOCS and OBDH units, etc.
     
    • Redesign of the panel and the attached functionalities as multifunctional structure panel where the non-structural functionalities are integrated into the panel.

      Verification of Composite Laminates under Cryogenic Thermo-Mechanical Loading
      Proposed activities:
       
      • Assess and identify the limitations of the commonly used approach for strength verification of composite laminates under cryogenic thermo-mechanical environment (including modelling, failure criteria with supporting test methods to determine allowable values).
      • Assess relevance of stacking sequences of plies in the laminate for resistance against cryogenic thermo-mechanical loading.

        Robotic manufacturing of fibrous structures in space

        Motivation: This study aimed to develop promising robotic fabrication methodologies for a fibre-based in-situ robotic fabrication process, for application in a lunar habitat as an alternative to existing additive manufacturing methodologies. Previous work has verified that fibre composite fabrication processes are capable of a high degree of automation and structural performance.
