Description of the development:
()
A highly effective binder and manufacturing technology based on it without the use of solvents of fire-resistant (self-extinguishing) carbon plastics with enhanced thermal and physico-mechanical characteristics based on the traditional EDT-69n for equipping aircraft and spacecraft have been developed. A fundamentally new method of forming a three-dimensional polymer structure and its nanostructuring was used.
