Abstract
A glass laminated structure includes a core of curable flowable material sandwiched between first and second glass panels. A pair of frame members sealed to the panels with an ultraviolet curing adhesive overlap marginal portions of the panels so that an overlapping portion of the core abuts the peripheral edges of the panels to absorb stress and inhibit delamination. The laminating apparatus includes platens with vacuum ports for securing the panels to the platens without excessive panel deformation, recessed portions for proper frame member alignment, and elastomeric seals supplanting the usual vacuum grease. The methodology proceeds by retaining the glass panels and frame members in position using the platens, and sealing the frame members to the panels. Then, the curable flowable material is introduced so that it flows between the frame members to abut the peripheral edges of the glass panels. The flowable material is then cured, with the overlapping portion of the flowable material bearing against the peripheral edges to offset stresses and inhibit delamination.
