Studies have been conducted on the influence of microwave electromagnetic fields on the magnitude of internal stresses in cured carbon fiber, glass fiber, and organic plastics, as well as unidirectional composites obtained by FDM technology from PEEK thermoplastic reinforced with continuous carbon fiber. A reduction in internal stresses as a result of microwave exposure was established, averaging 9%, 6.5%, 6%, and 5.4% for carbon fiber, glass fiber, organic plastics, and unidirectional reinforced PEEK, respectively. The reduction in internal stresses is small in value and is a concomitant effect; however, in the context of a certain increase in the safety factor and, consequently, the reliability of products made from polymer composite materials, it can be considered as another argument for the practical application of microwave technologies in the production of PCM products.
