Polymer filler for accelerated molding technology

Abstract

This paper presents the results of the study of a polymer filler for the “crush-core” rapid molding technology. Different formulations of the compositions, temperature regimes of curing were investigated, and the completeness of the passage of a chemical reaction under various temperature regimes was also considered. The depth of the curing reaction was separately studied in order to obtain a filler processed in a single technological cycle lasting no more than 1 hour at a temperature of 140°C, together with skins based on fiberglass prepreg.
