Abstract

This disclosure relates to adhering a layer of ductile material to surface portions of a brittle sheet and adhesively bonding thereto a rigid attachment.

Claims

1. A PANEL ASSEMBLY COMPRISING A PANEL OF BRITTLE SHEET MATERIAL SELECTED FROM THE GROUP CONSISTING OF GLASSES, CERAMICS, GRAPHITES, CARBON-LIKE MATERIALS, PLASTICS AND COMBINATIONS THEREOF, A DUCTILE METALLIC FOIL HAING A FIRST MAJOR SUR FACE THEREOF RIGIDLY BONDED BY A HIGHT TEMPERATURE RESISTANT HIGH STRENGTH RESINOUS CEMENT TO PORTIONS OF A MAJOR SURFACE OF SAID BRITTLE SHEET MATERIAL AND A RIGID EDGE ATTACHMENT EXTENDING BEYONG THE PERIPHERY OF SAID BRITTLE SHEET MATERIAL FOR ATTACHMENT TO A PANEL ASSEMBLY SUPPORT, AND BEING RIGIDLY BONDED BY A HIGH TEMPERAURE RESISTANT, HIGH STRENGTH RESINOUS

2. A panel assembly according to claim 1 wherein said metallic foil is selected from the group consisting of brass, kovar, titanium and stainless steels.

3. A panel assembly according to claim 1 wherein said metallic foil is bonded to said brittle sheet material by a phenoxy cement.

4. A panel assembly according to claim 3 wherein said phenoxy cement contains a particulate metal dispersed therein.

5. A panel assembly according to claim 1 wherein said panel assembly is comprised of a plurality of rigid, transparent plies of brittle sheet material bonded together by plastic interlayer material.

6. A panel assembly according to claim 5 wherein at least one of said rigid, transparent plies is composed of glass.

7. A panel assembly according to claim 6 wherein said glass is tempered.

8. A panel assembly according to claim 1 wherein said ductile foil is bonded to a marginal side surface portion of opposed major surface portions of said brittle sheet material.

9. A panel assembly according to claim 1 wherein said assembly is comprised of at least a pair of rigid transparent plies of brittle sheet material bonded together by plastic interlayer material, each of said plies of said pair of plies of brittle sheet material having a pair of opposed major surfaces having respective opposed marginal side surface portions, said ductile foil comprises pairs of foil portions, each foil portion being bonded to an extending conformably along a respective one of said marginal side surface portions defined by said opposed major surfaces of each of said plies of said pair of plies of said brittle sheet material, and said rigid attachment comprises pairs of spaced metallic frame members, each frame member being bonded to a respective one of said foil portions and extending around the periphery of a respective one of said rigid, transparent plies.

10. A panel assembly according to claim 9 wherein said ductile metallic foil portions are selected from the group consisting of brass, kovar, titanium and stainless steels.

11. A panel assembly according to claim 10 wherein at least one of said rigid, transparent plies is composed of glass.

12. A panel assembly according to claim 11 wherein said glass is tempered.
