On the radio-frequency inputs in dipolar heating of adhesives

摘要

The form of the radio-frequency(RF)or dielectric input expression in the heat equation which arises in the modeling of the curing of epoxy adhesive in bonding of composite was considered. two standard derivations of a commonly used expression for the RF heating derivations of a commonly used this context difficulties involving the associated inherent polarization assumption and asymptotic behavior of dielec- tric parameters as a function of the frequency of the RF signal were discussed. These difficulties cast doubt on the validity of the standard RF expression.
