Abstract
Thermally rigidised thermoset composites and UV rigidised composites are methods that have been widely studied in inflatable structures. However, these methods based on chemical rigidisation present some awbacks, as for example the influence of space environment in polymerisation and thus, in final properties obtained in the composite. Alternative and promising methods are passive cooled thermoplastics. The aim of this project has been to conduct further research in this new rigidisation technology. A study of different materials has been performed based on the final properties required in space conditions, but also properties specifically needed for folding, inflation and rigidisation steps. Thus, the approach has been planned in two phases. The first phase covers a material study and testing at coupon level, which has allowed the optimisation of the rigidisation process. The second phase deals with the manufacturing, testing and validation of a reduced size breadboard, consisting of a solar array composed by two lateral flexible solar panels (membranes) supported by a central rigidisable boom.
