    • Embodiments of a laminate including a first glass ply having first and second opposing surfaces defining a first edge having a first thickness, a second glass ply having third and fourth opposing surfaces defining a second edge having a second thickness that is less than the first thickness, and a polymer layer disposed between the second surface of the first glass ply and the third surface of the second glass ply are disclosed. In one or more embodiments, the first edge comprises any one of a roughness Ra of less than about 1300 nm and a root mean square (RMS) roughness of less than about 1700 nm, as measured along an area of about 0.5 square millimeters (mm2). In some embodiments, the first edge is substantially free of conchoidal fractures having a major dimension greater than 20 micrometers, as measured along an area of 0.60 square micrometers. Vehicles including such laminates and methods for forming such laminates are also disclosed.
    • 包括具有限定具有第一厚度的第一边缘的第一和第二相对表面的第一玻璃层的层压体的实施例,具有限定具有小于第一厚度的第二厚度的第二边缘的第三和第四相对表面的第二玻璃层, 并且公开了设置在第一玻璃层的第二表面和第二玻璃层的第三表面之间的聚合物层。 在一个或多个实施例中,第一边缘包括小于约1300nm的粗糙度Ra和小于约1700nm的均方根(RMS)粗糙度中的任何一个,沿着约0.5平方毫米(mm 2)的面积测量 )。 在一些实施例中,沿着0.60平方微米的面积测量,第一边缘基本上没有具有大于20微米的主尺寸的贝氏体断裂。 还公开了包括这种层压板的车辆和用于形成这种层压板的方法。
