SPS_TFP_SQ Report Summary

Project ID: 696376

Periodic Reporting for period 1 - SPS_TFP_SQ (TFP Strut Qualification)

Reporting period: 2015-10-01 to 2016-09-30

Summary of the context and overall objectives of the project

"The TFP Strut Qualification project addresses the work programme topic “spinning-in” of terrestrial solutions to challenges in space.
The tailored fibre placement (TFP) technology is "spinned-in" to the space industry in order to fundamentally improve the properties of a very common structural element for space applications: the strut.

The proposed technology addresses the following problems, creating a business opportunity on the space market:
1. Exceptional mass saving - is critical for all space missions.
2. Cost and manufacturing time reduction - is a natural requirement for all business and in particular space endeavours.
3. Thermal stability - is required for precise scientific missions.
4. Reducing the environmental footprint - is essential to meet the European and global challenge to protect the environment.

The overall objective of this project phase 2 is to qualify by extensive testing market relevant types of struts designed and manufactured applying the tailored fibre placement (TFP) technology. It will also include an extended business plan for the product."

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

Major achievements within the first reporting period have been:
• Requirements definition as fundamental input to the development process and to the detailed outline of the required outcome for this project.
• Derivation of strut concepts and realisation into detailed strut designs including analytical verification as basis for manufacturing and testing.
• Elaboration of qualification test plan and procedures as basis for testing preparation.
• Development of manufacturable soluble core technology as inner tool. This topic was unsolved for the prototype of Phase 1. Therefore, the achievement of this task has been considered as the key to manufacturing.
• Manufacturing of preform and strut representative samples to substantiate full strut manufacturing.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

First hollow prototype strut design and successfully tested for 5kN load weighs 55 g (grams).
Best performance product for the same 5kN load available on the market weighs ~200g (grams).

This is not just an incremental improvement, but a re-definition of the state-of-the-art.
Lightweight structures allow cost saving for space missions, reduction of the environmental footprint and are potential enablers of applications that are so far not feasible.
