A Study of the Temperature Distribution in a Polymer-Composite Rod When Heat-Treated with Microwave Radiation
Measurement Techniques. 2019. Vol. 62. No. 4. P. 365-370.
We propose a method for designing transversely illuminated traveling-wave microwave devices. Devices of this type produce a uniform 3D temperature distribution in a polymer-composite rod. We describe theoretical and experimental results from studies of the 3D temperature distribution in the rod, along with the advantages of microwave curing technology over traditional curing techniques for polymer composites.
