“…Contact molding technologies have been used in composite manufacturing industry for a long time and they are constantly under improvement. Traditionally, they are divided into one-stage, which include, for example, the technology of vacuum infusion and two-stage, where at the first stage -a prepreg is produced, and at the second stage-component is formed from it [1,2].A prepreg is a thermosetting molding composition consisting of a binding and reinforcing fibrous material (most often fabric or tape), which requires further curing and is processed into a polymer composite material by various methods [3][4][5].The prepregs are widely used in the aviation industry and in the manufacture of rocket and space elements, which is due to the high mechanical properties of the finished products.…”
