Microwave Power Absorption Model for Composite Processing in a Tunable Resonant Cavity*
Source abstract
Abstract
A five-parameter microwave power absorption model was developed for a simulation of power dissipation inside a fiber reinforced composite during microwave processing in a tunable resonant cavity. The five parameters are the power dissipation due to the electromagnetic (EM) waves from the sides, the magnitudes and the polarization angles of the incident TEM waves at the top and bottom of the composite with respect to the fiberdirection of the first encountered composite ply. The model was applied to simulate the temperature profiles during microwave heating of a fully cured 3” x 3”, 72-ply unidirectional AS4/3501–6 composite in a 7” ID tunable resonant cavity using 2.45 GHz microwave radiation. A good agreement was found between the simulated temperature profiles and the experimental data.
