Abstract
Apparatuses and methods for glass laminates having a controlled coefficient of thermal expansion are disclosed. In C one embodiment, a glass laminate includes a glass core having a core thickness (T) and a core coefficient of thermal expansion (CTE), 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 a first cladding thickness (T) and a first clad coefficient of thermal expansion (CTE), and the second glass cladding layer has a second cladding thickness (T) and a second clad coefficient of thermal expansion (CTE). The glass laminate has a laminate coefficient of thermal expansion (CTE) within a range of about 35×10/° C. to about 90×10/° C., the laminate coefficient of thermal expansion (CTE) defined by: CTE=((CTE×T)+(CTE×T)+(CTE× T))/(T+T+T).
