    摘要： It is now possible to economically produce, in series production, automotive glazing that has complex small radii feature lines (30). Such feature lines (30) are desirable as they can improve the stiffness of the glazing as well as contribute to the overall aesthetic and differentiation of the vehicle, allowing body lines to blend into and continue in the glazing. However, traditional automotive laminating methods do not lend themselves well to this type of product. Typically, the offset between the mating surfaces of the laminate must be very uniform. Such uniformity is difficult to achieve when producing small radii features. Rather than bending multiple layers with small radii feature lines that can be nested and subsequently laminated using standard plastic automotive interlayers, the invention makes use of a two part method for laminating, a dry lamination process and a wet lamination process, which requires only that the feature lines (30) be present in the outer glass layer (201).

    摘要： Glass laminates, comprising more than one glass composition, are becoming increasingly common as the industry moves towards lighter and stronger glazing. Bending dissimilar glass compositions can present problems. A mismatch in the glass viscosity curves, especially in the viscoelastic region of the compositions can result in one layer becoming softer than one of the other layers during the thermal bending process. As a result, economical processes, such as gravity or press bending in which multiple glass layers are simultaneously bent, may not be practical to use forcing the use of more expensive single glass layer bending processes. By thermal treatment processes the fictive temperature of at least one of the glass compositions prior to bending can be shifted to better match the other compositions allowing the glass layers to be simultaneously bent.

    摘要： Laminated automotive glazing, once limited to just the windshield, is finding more and more application in other positions in vehicles due to its ability to reduce weight, as well as to improve passenger safety, security and comfort. Designing a laminate that can serve as a direct replacement for tempered glass can be challenging Tempered glass is 4 to 5 times stronger than annealed glass and the lamination process has limitations that are not present with tempered. In particular, it is difficult to produce thin laminated glazing with holes. The laminate of the invention comprises strengthened thin glass layers in combination with laminated inserts to provide a thin laminated glazing with holes that has all of the advantages inherent in a laminate while retaining the reliability and utility of a tempered part and further can serve as a direct replacement for a tempered part.
