Can't a megalodon bite through it? How hard the PC board is!

In the Hollywood blockbuster "Megalodon", there is a scene where the female protagonist personally goes into the sea to hunt down Megalodon, and the cage used to protect her is specially customized with polycarbonate. Under the fierce attack of the megalodon's sharp teeth, it remained intact and undamaged! By now, I believe everyone has the most intuitive feeling about the impact resistance of polycarbonate PC sheet, the protagonist of today's article!

Although polycarbonate PC sheet is a plastic material, it is a high-performance engineering plastic and is known as the "king of plastics". The impact strength of PC solid board with the same thickness is 200-300 times that of ordinary glass, 20-30 times that of tempered glass, and 30 times that of acrylic with the same thickness. Even when dropped two meters down with a 3kg hammer, there are no cracks, earning it the nicknames of "unbreakable glass" and "steel that rings". At present, most of the anti-theft doors, safes and other projects in banks that require high security and impact resistance are made of PC.

Polycarbonate sheets are widely used in various scenarios due to their inherent characteristics.

1. Riot shield: refers to a defensive device similar to medieval shields used by armed police, riot police, or riot control forces, often made of polycarbonate material. Used to push and protect oneself during riot control, it can withstand attacks from hard objects, blunt objects, and unknown liquids, as well as low-speed bullets, but cannot withstand explosive fragments and high-speed bullets.

2. Bulletproof glass :It is a composite material made by special processing of glass and high-quality engineering plastics. It is usually a transparent material, usually consisting of polycarbonate fiber layers sandwiched between ordinary glass layers. The process of sandwiching a polycarbonate material layer in a regular glass layer is called lamination. In this process, a substance similar to ordinary glass but thicker than ordinary glass was formed. Bullets fired on bulletproof glass will puncture the outer layer of glass, but the polycarbonate glass material layer can absorb the energy of the bullet, thereby preventing it from penetrating the inner layer of the glass.

3. Aerospace: With the rapid development of aviation and aerospace technology, the requirements for various components in aircraft and spacecraft are constantly increasing. Due to the high impact resistance of PC boards, their application in this field is also increasing. According to statistics, there are 2500 polycarbonate components used on just one Boeing aircraft, with a single unit consuming approximately 2 tons of polycarbonate. On the spacecraft, hundreds of different configurations of polycarbonate components reinforced with glass fibers and protective equipment for astronauts are used.

This shows how hard polycarbonate is!Whether in daily life or extreme environments, polycarbonate PC sheets have demonstrated extremely excellent performance. From resisting the attacks of the most ferocious predators in nature to ensuring the safety of human life and property, to promoting technological progress, this magical material is changing our world with its unique charm.
