摘要

Objectives: Actuality of the study is based on rapid development of polymer composite materials and their increasingly greater application in space industry. Methods: Consequently this work is focused on optimization of technological parameters of impregnation of load-bearing rods of transformable guy-roped type aerial reflectors made of polymer composites by transfer molding method. The main approach to the study of this problem is simulation of transfer molding process with computer-aided engineering system by the finite element analysis. Findings: Features of simplification of geometric models of power rod elements and simulation of transfer molding process are described. Calculations of impregnation velocity of perform model, impregnation time as well as fields of resin pressure distribution by volume of perform model are carried out. Improvements: According to results of the calculations, type of resin feeding into perform volume is selected.
