Abstract: A stress-engineered frangible structure includes multiple discrete glass members interconnected by inter-structure bonds to form a complex structural shape. Each glass member includes strengthened (i.e., by way of stress-engineering) glass material portions that are configured to transmit propagating fracture forces throughout the glass member. Each inter-structure bond includes a bonding member (e.g., glass-frit or adhesive) connected to weaker (e.g., untreated, unstrengthened, etched, or thinner) glass member region(s) disposed on one or both interconnected glass members that function to reliably transfer propagating fracture forces from one glass member to other glass member. An optional trigger mechanism generates an initial fracture force in a first (most-upstream) glass member, and the resulting propagating fracture forces are transferred by way of inter-structure bonds to all downstream glass members. One-way crack propagation is achieved by providing a weaker member region only on the downstream side of each inter-structure bond.

The glass has a working point at which the glass has a viscosity of 104 dPa·s of at most 1350° C. The glass has a viscosity versus temperature profile and a coefficient of thermal expansion versus temperature profile of the glass are such that a variable (750° C.−T13)/(CTELiq−CTESol) has a value of at most 5*106 K2. The CTELiq is a coefficient of linear thermal expansion of the glass above a glass transition temperature Tg, the CTESol is a coefficient of linear thermal expansion of the glass in a temperature range from 20° C. to 300° C., and the T13 is a temperature at which the glass has a viscosity of 1013 dPa·s.

Abstract: An apparatus and method for bending and/or tempering glass substrate(s) are provided. The amount of near-IR radiation which reaches the glass to be bent and/or tempered is limited (e.g., via filtering or any other suitable technique). Thus, the IR radiation (used for heating the glass) which reaches the glass to be bent and/or tempered includes mostly mid-IR and/or far-IR radiation, and not much near-IR. In such a manner, coating(s) provided on the glass can be protected and kept at lower temperatures so as to be less likely to be damaged during the bending and/or tempering process. Heating efficiency can be improved. A ceramic (e.g., aluminosilicate) filter or baffle may be used in certain embodiments in order to reduce the amount of mid-IR and/or far-IR radiation reaching the glass to be tempered and/or bent.

Abstract: A tempered glass includes a glass sheet having a thickness of 2.3-3.5 mm, an average surface compressive stress of 1000-1300 kg/cm2, and a plurality of first and second belt-like regions. Each of the second belt-like regions is interposed between adjacent ones of the first belt-like regions. Each of the first belt-like regions has a width of 10-30 mm and a plurality of first reference points, each having a principal stress difference of 120 kg/cm2 or less, which is larger than principal stress differences at areas of each of the first belt-like regions which are peripheral to each of the first reference points. The first principal stress difference at each of the first reference points is located in a direction perpendicular to the length of the first belt-like regions. Lines connecting adjacent ones of the first reference points form a center line, as a reference line, of each of the first belt-like regions. Each of the second belt-like regions contain a plurality of second reference points, each having a second principal stress difference which is larger than principal stress differences at areas of each of the second belt-like regions which are peripheral to each of the second reference points. The second principal stress difference extends in at least two different directions, one direction being substantially perpendicular to the first direction of the first principal stress difference and being located at peripheral edges of each of the second belt-like regions, and another direction being oblique to the first direction of the first principal stress difference. The two different directions of the second reference points forms a pattern. The pattern is a snaking line having undulations which are approximately trapezoidally-shaped.
