ABSTRACT:
A method of making a curved, shatterproof glass laminate for an automotive orother type transportation vehicle window or sun roof, which comprises at least one heat tempered or heat strengthened glass layer, which may be a low E glass type, at least one internal combination elastic shock absorbing-adhesive plastic layer of, for example, polyvinyl butyral material, and at least one antilacerative plastic layer of, for example, polyester or polycarbonate material, and/or a polyester material having a scratch-resistant or self-healing coating. The laminate may be formed from a laminate layup by engaging the antilacerative layer with a mold member and subjecting the resultant assembly to vacuum, heat and pressure in an autoclave. The resultant laminate may have a thickness so as to be readily usable for replacement or new manufacture in a standard existing frame or holder. The mold member is formed of a relatively thin hard plastic, such as a polyester or a polycarbonate, a relatively thin metal, such as stainless steel, or be of a normally flat planar elastic, flexible resin-impregnated fiber glass construction which does not require premolding. When two glass layers are used, they may be bonded together by a liquid adhesive to compensate for curved shape variations in the layers.
