    Abstract

    Rapid heating and curing of polymer resins has been shown as one of the advantages of microwave methods over conventional thermal processes. This paper studies if microwave heating efficiency and curing rate can be further enhanced with increasing material dielectric properties. Carbon black was added into epoxy materials - diglycidyl ether of bisphenol A (DGEBA) / diaminodiphenyl sulfone (DDS) - to increase the dielectric properties of the resin. Microwave heating processes with and without additives were compared. As the concentration of carbon black increased, the power requirement decreased to maintain the same isothermal curing temperature. This result showed that conducting additives enhanced the microwave heating efficiency by increasing material dielectric properties. However, the addition of carbon black into the resin did not further enhance the microwave curing rate of DGEBA/DDS. Instead, the microwave curing rate decreased slightly as the additive concentration increased. This might result fr om the lower power deposition at higher additive concentration.
