How Was Unbreakable Glass Discovered? – Webtekno

Who could have thought of it first and how? ‘an unbreakable glass’ to produce?

Besides, how was such an invention possible? Even though you may think that this technology can only happen today, it actually It dates back a century!

In the early 20th century, French chemist Edouard Benedictus developed an innovation to increase the durability of glass.

It is something we use in many parts of our daily lives. cam materialIt was invented in 1903 when Benedictus developed the first example of laminated safety glass by adding a plastic material called celluloid between the layers of glass. This discovery was a turning point in the use of glass for security purposes.

Benedict’s inventionIt aimed to eliminate the fragility of glass and make it resistant to bullets. Celluloid layers added to the internal structure of the glass prevented the glass from breaking, making it a stronger and safer material.

What are the developments today?

Today bulletproof glassIt is generally produced using a plastic material called polyvinyl butyral (PVB). PVB is available in thin plastic sheets placed between sheets of glass.

These layers enable the glass to gain greater durability. During the production process, glass and PVB sheets are heated under high temperature and the plastic layers stick to the glass, allowing the layers to come together. This process increases the strength of the glass and makes it resistant to external factors such as impacts and bullets.

Although the thickness of bulletproof glass varies depending on the purpose of use, it is generally 10 cm.

More than one glass and Finding the PVB layerincreases the glass’s capacity to absorb impact energy. So what makes it so durable?

Normal glass does not have the capacity to absorb the energy of bullets. Therefore, when a bullet hits the glass glass often shatters and the bullet continues to move forward without any significant loss of momentum upon impact. However, the design of shatterproof glass does not prevent the bullet from shattering the glass; instead, plastic layers inside the glass keep glass shattering in check.

PVB layers prevent the shattered glass from disintegrating.

In this way, the bullet kinetic energy of glass and PVB layers It spreads and is absorbed. As a result, the bullet has difficulty penetrating the glass and its kinetic energy is largely absorbed and remains in place.

At work This invention of a French chemist Today, its use in almost every field saves our lives.
