Abstract
A method of using at least one polymerisable resin R1 is disclosed. According to some aspects, the resin R1 is selected from the group consisting of epoxidised polybutadiene resins, epoxidised polyisoprene resins, epoxidised polysiloxane resins, epoxidised triglyceride resins and epoxidised polyether resins. The resin R1 having at the non-polymerised state a total mass loss (TML) value lower than about 10%, a recovered mass loss (RML) value lower than about 10%, and a collected volatile condensable material (CVCM) value lower than about 1%, as determined in accordance with standard ECSS-Q-70-02A of the European Space Agency. The resin R1 also characterized by an epoxide equivalent weight of about 100 to 600 g/mole. The resin is configured for the manufacture of a composite material for use in space, and more specifically, a composite material of a Gossamer structure. Polymerisable resin compositions are also disclosed which are useful in the manufacture of composite materials for use in space.
