EVALUATION OF SHRINKING MATERIAL OF THICK-WALLED PLATES FROM PCM AT INTERMEDIATE FORMING MODES
The article describes a method for manufacturing thick-walled technological plates (TTP) from square blanks of a carbon prepreg of twill weaving. In the manufacturing process, every 40 layers, the material was pressed in an autoclave at overpressure and temperature. After hot pressing (GP), material shrinkage was evaluated to predict the thickness of 200-layer wafer blanks. The data on changes in the thickness of the obtained samples of carbon plastics are given, depending on the choice of the mode of conducting the intermediate hot pressing. Based on the obtained shrinkage data for various GPs, the optimal GP mode was determined to obtain the required TTP thickness with the required thickness of the material monolayer in the workpiece.
