Two types of complex solvent-free binders were developed in the course of scientific research for radiation-induced technologies used in the manufacture of large-size items. A manufacturing process could be accomplished through a single stage of radiation curing or through a two-stage procedure, which implies radiation manufacture of the long-lived prepregs and subsequent thermo-chemical hardening. The developed binders make it possible to obtain composition materials with high heat stability (glass transition temperature ~260°C) and radiation resistance (>10 MGy).
