ABSTRACT:
A method of producing a bonded laminate by sealing round the edges of a pair of face-to-face spaced sheets of frangible material, introducing into the envelope so formed a liquid resin composition and solidifying the liquid, the seal around the sheets being formed by gas-permeable, resin-impermeable material so that when the resin is introduced the sheets can be sealed completely and trapped air can escape through the seal. This permits very precise control of the amount of resin in the laminate and avoids difficulties involved in the removal of air bubbles.
