Substantiation of technological parameters in the production of composite polyphenylene sulfide-based tape

The purpose of the study was to select technological parameters of the production line of unidirectional thermoplastic polyphenylene sulfide-based tapes. The selection was made relying on the variation of the tape speed, the temperature of the sub-melting furnace, and the calendering module in the simulation of heat transfer processes. Modeling of heat transfer was based on the results of tests to determine the temperatures of phase transitions of a thermoplastic polymer in the composition of composite material and the dependence of the heat capacity of the composite on temperature. The indicated properties of the material were determined by analyzing the dependences obtained during differential scanning calorimetry and thermogravimetric analysis. As a result, the allowable range of distances between the polymer binder melting furnace and the calendering module was determined, which provides the necessary tape temperatures at the stages under consideration and the manufacturability of production. The permissible range of distances between the calendering module and the coiling module was also determined.
