Research into the use of Carbon Fiber Reinforced Polymers (CFRP) in space structures. Here are the key aspects of this technology:
Research Objective
The aim was to investigate the potential of CFRP materials in space projects to reduce mass and costs while maintaining high stiffness and strength.
Tested Structures
Scientists focused on two structures:
- The European Standard Payload Rack (ESPR) from the International Space Station
- A proposed Lightweight Secondary Structure (LSS) for future crewed missions beyond Low Earth Orbit
Testing Process
Tests were conducted in three phases:
- Initial validation of resins for space compatibility
- Basic assessment of mechanical and thermal properties of materials and structures
- Production of two 2-3 meter pultruded beam demonstrators with different design solutions
Results
The tests showed that:
- Pultrusion technology is fully compatible with use in crewed structures
- Using CFRP allows for significant mass savings
- These materials increase the stiffness of secondary structure elements
- They potentially can be used in structures such as pressurized habitation modules
This technology opens up new possibilities in designing lighter and more efficient space structures, which is crucial for future exploration missions.
