FIELD: aeronautical engineering and rocketry; manufacture of rocket antenna domes and radioparent ports; manufacture of articles resistant to stable heating up to 800°C. ^ SUBSTANCE: proposed method includes impregnation of multi-layer glass fabric with organic binder, molding and hardening of binder; after hardening of binder, it is subjected to heat treatment at temperature of 250-350°C continued for 1-2 h and followed by holding in acetone for 1-2 h and impregnation with silicon organic resin and polymerization at temperature of 250-350°C for 3-4 h. Proposed method enhances heat stability of articles made from glass-reinforced plastics working under conditions of one-sided intensive heating up to 800°C at retained strength properties and dielectric characteristics. ^ EFFECT: enhanced efficiency; retained high strength properties and dielectric characteristics. ^ 1 tbl, 12 ex |
