Reinforced with various kinds of fibers and fabrics based on them, polymer composite materials are widely used in modern technology. This fact can be explained by the fact that they have a higher specific strength and corrosion resistance compared to known metals and alloys, as well as one-component polymers. The performance of structures made of polymer composite materials is negatively affected by anisotropy, the dependence of strength and stiffness on the direction of action of operational loads, brittleness, and reduced impact strength. In addition, composite materials are often subjected to physical modification. One of the effective methods of such physical modifications is the using of a microwave electromagnetic field. So, the modeling of a physical processes in a composite material under microwave exposure and study how it's strength characteristics changing are important tasks. An experimental study of a composite fiber under microwave heating is considered. The fiber consists of epoxy resin as an outer layer and of a graphite or glass rod as an inner core. Based on the results of the experiment, the principles for constructing a mathematical model of such composite materials were developed. Based on the developed principles, a mathematical model of thermal heating of the composite under microwave exposure was formulated. [ABSTRACT FROM AUTHOR] |
