Abstract
A laminated glazing panel (10) has at least one sheet of glass having a thickness of between 0.8 mm and 3.5 mm. The glass sheet has: a) an edge compression stress of between 20 MPa and 90 MPa; and b) a surface compressive stress at a central portion of the glass of between 2 MPa and 39 MPa. The glazing panel may be used as a laminated automotive glazing. A method of manufacturing a laminated glazing panel is also disclosed, comprising individually bending two sheets of glass and subsequently assembling and laminating the two sheets of glass together.
Claims19
A laminated glazing panel comprising at least one sheet of glass having a thickness of between 0.8 mm and 1.7 mm characterised in that glass sheet has:
- a) an edge compression stress of between 20 MPa and 80 MPa;
- and
- b) a surface compressive stress at a central portion of the glass of between 5 MPa and 60 MPa, the edge compression stress being greater than the surface compressive stress.
A laminated glazing panel comprising at least one sheet of glass having a thickness of between 0.8 mm and 1.65 mm, characterised in that the glass sheet has:
- a) an edge compression stress of between 20 MPa and 80 MPa;
- and
- b) a surface compressive stress at a central portion of the glass of between 5 MPa and 60 MPa, the edge compression stress being greater than the surface compressive stress.
A glass sheet adapted to be assembled as a laminated glazing panel comprising at least one sheet of glass having a thickness of between 0.8 mm and 1.7 mm characterized in that the glass sheet has:
- a) an edge compression stress of between 20 MPa and 90 MPa;
- and
- b) a surface compressive stress at a central portion of the glass of between 5 MPa and 60 MPa, the edge compression stress being greater than the surface compressive stress.
