Strength of adhesive bonds to fragile objects with complex shapes tested easily with vacuum chucks. In bond-strength test, contact surface of chuck pressed against matching surface of bonded tile. Vacuum line extending through fine bore in chuck creates vacuum at chuck-and-tile interface. Thus, when chuck pulled away, atmospheric pressure tends to push tile away with chuck. If adhesive resists predetermined pull exerted by chuck on tile, bond acceptable. Originally developed for vacuum chucks used on silica tiles attached to outer surface of Space Shuttle orbiter, used to custom-fabricate chuck for specific tile.
