differences were observed between formulations with POSS concentrations of 2.5%, 5%, and 10%, likely due to solubility limitations with higher POSS content. This study also evaluated the material’s resistance to extreme humidity, with CE demonstrating strong hydrophobic properties. POSS further enhanced moisture resistance—an important factor for maintaining mechanical integrity under high-humidity conditions.
The combination of BMI and CE, along with carefully selected additives such as DBA and POSS, provides a promising solution for 3D printing in outer space. The materials developed in this study exhibit strong mechanical and thermal properties, as well as resistance to atomic oxygen and outgassing. However, further research is needed to optimize the solubility of POSS in the BT resin to fully realize its potential. These findings open the door to the potential development of new materials able to handle extreme conditions in outer space, thus increasing the possibility offuture space missions and other advanced applications.
