Abstract
A patch is placed at one end of a repaired long crack in a windshield to prevent the repaired long crack from being overstressed and separating under load, which may be caused by flexing or differential thermal expansion. The patch spans the crack laterally and is placed adjacent an end of the crack, generally very near the edge of the windshield. The patch is bonded to the glass to reinforce the crack by carrying loads tending to separate the crack. The patch material is preferably at least as rigid as the glass and is bonded to the glass by a strong adhesive such as an epoxy resin.
