The effect of exposure to a microwave electromagnetic field on samples of cured carbon-, glass-, and organoplastics on an epoxy matrix on the strength and change in the nature of interlayer damage during bending deformations has been studied. An increase in the limiting stresses by 14.5, 9.1 and 11%, respectively, a decrease in the size of the delamination region during deformation by 1.5-2 times and its predominant localization in the internal volume of the composite was established. In the control samples, the exits of interlayer cracks to the surface of the material are noted. Keywords: polymer composite materials, flexural strength, interlaminar shear, damage, microwave electromagnetic field.
