Broken Laminated Tempered Glass

Tempered glass when broken forms many small bits rather than shards.

Broken laminated tempered glass.

Laminated glass when broken remains in place as in a frame thus preventing any glass from falling out and possibly injuring bystanders while also preventing fall though. Although dull these can still be a hassle. The surface compression of heat strengthened glass makes it approximately twice as strong as annealed glass. The glass will tend to stay together and case one in is broken thus qualifying as a safety glazing material.

Laminated glass is beneficial for soundproofing. Laminated glass laminated glass is made of two pieces of glass held together by a plastic film or resin. When laminated glass is broken it is held in place by an interlayer typically of polyvinyl butyral pvb between its two or more layers of glass which crumble into small pieces. It is known to be 4 5 times stronger than regular glass and can withstand temperatures up to 295 degrees celsius.

Laminated glass aids in the screening of uv radiation. Laminated glass is basically a glass sandwich. The research presented herein aimed to simulate the structural behavior of laminated glass with all the glass layers broken by means of the discrete element modeling. The former is called tempered or toughened glass and is used in shower doors refrigerator trays architectural glass doors and tables bullet resistant glass and smartphone screen protectors a rather recent development.

When broken the pieces are held together by the plastic layer reducing risk of injury from shards of glass. Tempered glass is very safe but if somehow broken still results in loose pieces of broken glass. The plastic portion of laminated glass may be clear or tinted. One of the biggest benefits of laminated glass is that if it does break the broken glass will stick to the plastic rather than falling to the floor.

When tempered glass is broken as shown above it shatters into thousands of tiny pebbles practically eliminating the danger of human injury caused by sharp edges and flying shards of glass. Laminated glass is composed layers of glass and plastic held together by an interlayer. Laminated safety glass keeps those pieces of glass safely in place. This paper focuses on laminated glass composed of two layers made of tempered glass and an interlayer made of either a totally compliant or a relatively stiff material.
