    • Apparatuses and methods for glass laminates having a controlled coefficient of thermal expansion are disclosed. In one embodiment, a glass laminate includes a glass core having a core thickness (T core ) and a core coefficient of thermal expansion (CTE core ), a first glass cladding layer and a second glass cladding layer. The first glass cladding layer and the second glass cladding layer are arranged such that the glass core is disposed between the first glass cladding layer and the second glass cladding layer. The first glass cladding layer has afirst cladding thickness (T clad1 ) and a first clad coefficient of thermal expansion (CTE clad1 ), and the second glass cladding layer has a second cladding thickness (T clad2 ) and a second clad coefficient of thermal expansion (CTE clad2 ). The glass laminate has a laminate coefficient of thermal expansion (CTE L ) within a range of about 35 x 10 -7 /°C to about 90 x 10 -7 /°C, the laminate coefficient of thermal expansion (CTE L ) defined by: CTE L = ((CTE core x T core ) + (CTE clad1 x T clad1 ) +(CTE clad2 x T clad2 )) / (T core + T clad1 + T clad2 ).
    • 公开了用于具有受控热膨胀系数的玻璃层压板的设备和方法。 在一个实施方案中,玻璃层压材料包括具有核心厚度(T core)和核心热膨胀系数(CTE core)的玻璃核心,第一玻璃包层 和第二玻璃包层。 第一玻璃包层和第二玻璃包层设置为使得玻璃芯布置在第一玻璃包层和第二玻璃包层之间。 第一玻璃包层具有第一包层厚度(T sub1 clad1)和第一包层热膨胀系数(CTE clad1),并且第二玻璃包层具有第二包层 厚度(T sub2 clad2)和第二包层热膨胀系数(CTE clad2)。 该玻璃层压材料具有在约35×10 -7 /℃至约90×10 -5℃范围内的层压热膨胀系数(CTE L -7 /℃,由下式定义的层压热膨胀系数(CTE L):CTE =((CTE < (CTE包层1×T包层1)+(CTE包层2×T <子包层1) > clad2))/(T core + T clad1 + T clad2)。
