High-Performance Thermoplastics for Lunar Exploration

Over the last decade, advanced engineering thermoplastics (polyether ether ketones (PEEKs), polyetherimides (PEIs), etc.) have received increased attention and interest for automotive, energies, aeronautic and aerospace applications. In these domains, high-performance thermoplastics are being developed to bring lightness in combination with exceptional mechanical, thermal and chemical properties. For spatial and/or lunar environment applications, various parameters should be considered when developing material formulations, including tolerance to extreme temperature changes (- 200° C to + 100° C), resistance to abrasive and electrostatic nanoscale dust, adequate outgassing properties, and resistance to high-energy radiations.

The main objective of this work is to develop high-performance polymer blends/nanocomposites materials for the design of the next generation of lunar rovers. This work is part of a multidisciplinary project made possible by the cooperation between the Research Center for High Performance Polymer and Composite Systems (CREPEC), a FRQ-NT Strategic Cluster, and the Canadian Space Agency.
