Temperature Effect of Microwave Heating of Cured Structural Epoxy-Carbon Filled Plastic on Interlayer Shear Stresses

Abstract—Changes in limiting interlayer shear stresses in a loaded cured carbon-fiber plastic after exposure to a microwave electromagnetic field with a frequency of 2450 MHz at different energy flux densities have been studied with allowance for the temperature factor and time. It is shown that, at a rational combination of the energy flux density and time ((17–18) × 104 μW/cm2 and 2 min, respectively), the limiting stresses increase by 17% on average as compared with the references samples.
