MICROWAVE-BASED GLASS LAMINATE FABRICATION

摘要

Methods of fabricating a glass laminate is provided. According to one embodiment, a glass laminate comprised of a microwave absorbing layer and a microwave transparent layer is formed. The microwave absorbing layer is characterized by a microwave loss tangent δH that is at least a half order of magnitude larger than a loss tangent δLof the microwave transparent layer. An area of the glass laminate is exposed to microwave radiation. The exposed area comprises a cross-laminate hot zone having a cross-laminate hot zone temperature profile. Substantially all microwave absorbing layer portions of the hot zone temperature profile and substantially all microwave transparent layer portions of the hot zone temperature profile reside above the glass transition temperature TG of the various layers of the glass laminate prior to impingement by the microwave radiation. In accordance with another embodiment, a method of fabricating a glass laminate is provided where the exposed area of the glass laminate is characterized by a viscosity below approximately 1×104 poise.
