Influence of electrophysical impacts on the flexural strength of a cured monolayer reinforced with continuous carbon fiber

Abstract

The effect of ultrasonic and microwave treatment of a monolayer formed by three-dimensional printing from prepregs reinforced with continuous carbon fiber on its three-point bending strength has been investigated. Empirical strain–stress relationships were obtained and the microstructure was investigated. The highest efficiency of electrophysical treatment (increase by 54–72 %) is observed for specimens exposed to microwave field in the deformation range of 0.5–1.3 mm.
