The University of Surrey in the UK has developed an ultra-light and stable carbon fiber-reinforced polymer (CFRP) strong multi-layer nano-barrier that can be used to construct high-precision instrument structures for future space flight.
CFRP is used in current spaceflights, but its application is limited because the material absorbs moisture. It is usually released in the form of gas during the performance of tasks, causing the material to expand and affecting the stability and integrity of the structure. Engineers try to minimize the problems caused by CFRP by using a long and expensive process.
Surrey`s engineers have shown that its thin nano-barrier (thickness is only sub-micron) is less sensitive to surface stress and pollution compared to the tens of microns of current space flight coatings, even after multiple thermal cycles Can maintain its integrity.
Professor Ravi Silva, director of the Institute of Advanced Technology at the University of Surrey, said: "These results show that our barriers can avoid the high cost and danger of using carbon fiber-reinforced polymers in space flight."
Christian Wilhelmi, head of mechanical subsystems and research technology at Airbus Group ’s Defense and Space Company, said: “For years, we have been using carbon fiber composite materials in our spacecraft and instrument structures, but the newly developed nano-barrier will allow us to build A new generation of non-vented CFRP material, which has greater dimensional stability and can be used in optical devices. "
Professor David Sampson, the deputy dean of research and innovation at the University of Surrey, said: "This research project continues the long-term close relationship between the University of Surrey and Airbus. Advanced spacecraft materials are another excellent support for the University of Surrey in supporting the space department Example. I look forward to more brilliant progress in the relationship between Surrey and Airbus in the coming years. "
