| Popis: | Improving the operational properties of epoxy composites makes it possible to extend the scope of their application. One of the techniques to enhance the strength and durability of epoxy composites is the use of magnetic treatment. In order to modify polymeric compositions under the influence of a magnetic field, it is necessary to maintain the optimal treatment modes and time-temperature conditions, determining which is the aim of this research. The result of the conducted experimental research is the established influence of parameters of an alternating magnetic field on physical-mechanical properties of the modified epoxy composites. We investigated patterns in the influence of proportionality coefficients, integration and differentiation coefficients in the algorithm to control magnetic treatment on impact viscosity and heat resistance of the modified epoxy composites. The optimum values for the frequency of an alternating magnetic field during treatment of epoxy composites were determined. We examined dependences of the content of a finely-dispersed ferromagnetic filler on residual stresses and temperature in the zone of magnetic treatment. Research into epoxy composites was accompanied by the parallel tests of properties related to the effect of similar temperature at magnetic treatment. The law of change in temperature parameters without magnetic treatment was assigned similarly to that of magnetic treatment. This paper reports results of the mathematical planning of the experiment and correlation dependences of magnetic field induction and the content of a filler on heat resistance of the modified epoxy-composite material. The research identified limiting values for the content of a filler and treatment modes of epoxy-composite materials, which ensure the improved performance properties. Our study is important for improving the technological process to modify epoxy compositions with magnetic treatment |
