Researches of influence of the microwave oven of an electromagnetic field of various brought power on physicomechanical characte-ristics of layered composite materials are executed. Influence of the microwave oven of an electromagnetic field with a frequency of 2450 MHz is studied at the specific power of 4, 17,5 and 31 W/cm3 on cylindrical samples from carbon fabrics. The limit tension of a cut, bend and the elasticity module at a longitudinal bend of samples after heat treatment on the existing technology were estimated and after the microwave oven of processing. It is shown that the microwave oven an electromagnetic field of the specific power of 17,5 W/cm3 at time of influence of 2 minutes causes increase in duration of functioning of a design from carbon fabrics from 1,5 to 4,5 times depending on the scheme of loading and increases the limit tension of a cut of material for 35−38%. In the studied range the flexural durability and longitudinal stability of samples practically didn\'t change. The conclusion is drawn on prospects of further researches in this direction for the purpose of creation of technologies of formation of composite materials with the set properties of the increased durability not only constructional appointment, but also for production of effective waveguide systems of powerful radio engineering microwave ovens of devices.
