The Matrix

Based on studies of the microstructure of the matrix of cured polymer composite materials and the area of its contact interaction with reinforcing fibers, the hypothesis of its structuring in the microwave electromagnetic field with an increase in the contact interaction surfaces due to an increase in the number of agglomerates with small transverse dimensions and a decrease in porosity in the macro- and mesopore regions is substantiated. These effects can be used as a basis for increasing the strength characteristics and uniformity of their values after exposure to a microwave electromagnetic field. The results of this work can be used in the development of technologies for finishing hardening of products made of carbon and fiberglass for various transport and energy systems.

The Impact

Due to the widespread use of carbon fiber-reinforced polymer composite materials (PCM) in the structural elements of aircraft with a distributed surface layer of lightning-proof coating (MFP) in the form of metal grids to reduce the risk of lightning strikes and the possibility of increasing their strength characteristics by processing in the microwave electromagnetic field, the need to study the impact of this method of processing on the resistance of PCM to high voltage electrical discharges. The studies of the impact of the discharge voltage 180…200 kV on samples of PCM with the minimum wage and no minimum wage. It is established that pretreatment of samples of the cured polymer composite MW in a microwave electromagnetic field energy flux density (17…18)104 µw/cm2 does not degrade their molniezaschita characteristics and contributes to reducing the size of the damaged area up to 1.5 times. Samples processed in the microwave electromagnetic field without MSP do not have delaminations and burns in contrast to the control ones. The obtained results indicate the possibility of strengthening treatment in the microwave electromagnetic field of structural elements of carbon fiber distributed in the surface layer of the MSP in the form of a metal grid.
