Influence of External Physical Impacts on Microwave Characteristics of Composite Materials Containing Carbon Micro- and Nanoinclusions
Electrophysical properties of composite materials based on an epoxy glue with inclusions in the form of carbon nanotubes and particles of fine-dispersed graphite in a range of frequencies from 0.1 to 6 GHz are investigated. Research of influence of physical factors (ultrasound, pressure) on value of complex dielectric permeability of a composite material with carbon micro- and nanoinclusions, during its manufacturing is carried out. It is shown, that there is optimum time of processing of a composite material ultrasound at which for the set concentration inclusions it is reached maximum it conductivity. It is received, that with growth of value of external pressure, at consolidation a composite material, the imaginary part of dielectric permeability of a composite increases under the linear law.
