USE OF POLYMERISABLE RESINS WITH LOW VACUUM DEGASSING FOR MAKING SPACE-GRADE COMPOSITE MATERIALS

摘要

The invention relates to the use of at least one polymerisable resin selected from the group comprising epoxidised polybutadiene resins, epoxidised polyisoprene resins, epoxidised polysiloxane resins, epoxidised triglyceride resins and epoxidised polyether resins having at the non-polymerised state: a total mass loss value lower than 10%, a relative mass loss value lower than 10%, and a condensable volatile-material value lower than 1% as determined according to standard ECSS-Q-70-02A; and an equivalent epoxidised weight of 100 to 600 g/mole. The resin is used for producing a space-grade material and more particularly a composite material having a Gossamer structure. The invention also relates to polymerisable resin compositions used for the production of space-grade composite materials, and to such composite materials.
