Studying the reinforcing microwave modification of aeronautical-purpose structural components made of composite materials

Abstract

The strength characteristics of composite carbon and fiberglass plastics are studied after their modification by microwave radiation of various power inputs. It has been established that, in comparison with the control samples, the microwave effect on the finally shaped object at a certain power level for each material increases the limiting flexural stresses of the CFRP by 47-53% and the GRP by 60%. At the same time, significant changes in the microstructure are noticed, which manifest themselves in an increase in its homogeneity and density as the contact points of the matrix agglomerates and reinforcing fibers increase.
