New Nano-Barrier for Composite Material Could Strengthen Spacecraft Payloads

Researchers at the University of Surrey have developed a robust nano-barrier for carbon fiber reinforced polymers (CFRPs) that could be used to strengthen and stabilize high-precision instrument structures for space missions. CFRPs are used in current space missions, but their applications are limited because they absorb moisture. This moisture is often released as gas during a mission, causing the material to expand, which affects the stability and integrity of the structure. To minimize this problem, engineers may perform procedures such as drying, recalibrations, and bake-out, but these may not resolve the issue. The Surrey team’s multilayered nano-barrier bonds with the CFRP and eliminates the need for multiple bake-out...
