METHOD OF REINFORCED PLASTICS PRODUCTION Russian patent published in 1995 - IPC

FIELD: chemical industry. SUBSTANCE: method of reinforced plastics production provides for fillers impregnation by ЭДТ-69НУ binding stuff, following prepregs heating from room temperature with speed of 2.3 - 2.7 C/min to maximum hardening temperature and holding the temperature till full hardening. In the case during heating process electric conductivity and tangent of dielectric losses angle are constantly being fixed and as measurements achieve permanent values, hardening process is considered finished. EFFECT: 3 - 4 folds decrease of hardening period; simplified terms of forming; production of visually uniformed, porousless, without physical defects monolithic glass-carbon plastics with hardening degree of no less than 96 % and guaranteed quality; capability to exercise approximate analysis during production process. 2 tbl
