Abstract
A glass laminate is produced using infrared emitters to deliver thermal energy to an unbonded glass laminate assembly. Heat may be conducted to the glass laminate by at least one ceramic glass substrate that absorbs at least a portion of the infrared radiation from the emitters, thereby bonding the glass laminate assembly more quickly and efficiently than a conventional vacuum bag process.
Claims15
A method for preparing a glass laminate, the method comprising:
- bringing a first side of an unbonded glass laminate into contact with a first ceramic glass substrate, the unbonded glass laminate including at least one material layer disposed between two sheets of glass;
- bringing a second side of the unbonded glass laminate into contact with a second ceramic glass substrate, wherein edges of the unbonded glass laminate are inward of edges of the first and second ceramic glass substrates:
- applying a seal around the unbonded glass laminate to create a sealed area;
- drawing a vacuum within the sealed area;
- irradiating the first ceramic glass substrate with infrared energy by a first infrared emitter to bond the glass laminate;
- releasing the vacuum;
- and
- separating the bonded glass laminate from the first ceramic glass substrate,
- wherein the sealed area is bounded by the first and second ceramic glass substrates and an elastomeric seal that extends around a perimeter of the first and second ceramic glass substrates.
