Methods for forming patterns in thin glass laminate structures

A method of cold forming a glass laminate structure comprising the steps of:

• assembling a multi-layer structure having two buffer plates, one or more non-deformable materials adhered to a surface of one or both of the two buffer plates and a glass laminate structure intermediate the two buffer plates, wherein the glass laminate structure includes two sheets of glass and a polymer interlayer intermediate the two sheets of glass and wherein the one or more non-deformable materials form a pattern;
• placing the assembled structure in an autoclave;
• cold forming the glass laminate structure in the autoclave by heating the assembled structure to a temperature about 5 to 10 degrees above the softening point of the polymer interlayer for a predetermined period of time at a predetermined pressure;
• removing the assembled structure from the autoclave;
• and
• removing the glass laminate structure from between the buffer plates and one or more non-deformable materials wherein the pattern formed by the one or more non-deformable materials has been transferred to the glass laminate structure as a function of variances in thicknesses of the glass laminate structure.
