STUDY OF THE EFFECT OF THE MICROWAVE RADIATION SOURCE OF PROCESSING OF PREPREGS PKM STRENGTH CHARACTERISTICS BASED ON AN EPOXY RESIN REINFORCED WITH DIFFERENT YARNS
This paper studies the application of microwave oscillations for physical modification of thermosetting epoxy resin reinforced with different threads. In these materials, the polymer matrix is a cured epoxy resin. The influence of microwave on the structure and properties of thermoset reinforced by different threads. For polymeric reinforcement necessary to select the optimum content of the filaments, temperature, line speed, and the processing time of the microwave source power fluctuations. Actual direction of reinforcement polymer modification technology is to improve the strength characteristics, which can be achieved by brief pretreatment prepreg microwave radiation. Wave microwave processing affects competition and cross-linking of linear growth macrochains when cured towards accelerating the process of cross-linking. This treatment resulted in a further structuring of polymers and the resulting changes in the structuring of the strength characteristics.
