Influence of microwave electromagnetic field on interlayer strength in cured polymer composite materials

Abstract

It has been established that exposure to a microwave electromagnetic field with an energy flux density that is rational for each type of composite (carbon-, glass-, organoplastic) contributes to an increase in the specific work of delamination by 18.6%, 12% and 20%, respectively, which satisfactorily correlates with an increase in strength of these materials under three-point bending and interlaminar shear. Keywords: carbon fiber reinforced plastics, fiberglass plastics, organoplastics, delamination, microwave electromagnetic field.
