Microwave method of polymeric composite pipes curing
Theoretical and experimental results of curing of polymer composite pipes with the use of microwave radiation energy are presented. The results of studies on the accelerated curing of polymer composite pipes with diameter of 2000 mm, thickness of 36 mm at a temperature of +200°C and at anelectromagnetic field frequency oscillation of 2450 MHz and the output microwave power of 115 kW in a beam-type microwave device are given. The temperature deviation from the nominal value on the outer surface of the pipe is absent, and in the thickness of pipe does not exceed 5°C. A method of composite pipes curing can reduce energy costs, increase productivity and improve working conditions of staff.
