METHOD OF MOLDING PROCESS CONTROL FOR ARTICLES MADE OF POLYMERIC COMPOSITES Russian patent published in 1998 - IPC

FIELD: chemical industry. SUBSTANCE: in process of article consolidation in mold dielectric parameter of material is measured periodically. Then it is compared with standard value, and as soon as optimal value of material characteristic is obtained, heating is stopped. Standard value is determined by graph which is correlation dependence of variations of strength and dielectric permeability from consolidation time. Correlation dependence is obtained by means of mechanical tensile tests of specimens prepared in compliance with process of consolidated article molding. EFFECT: reduced time of hot molding process. 1 cl, 2 dwg
