Discover the science behind Kevlar; The ultimate synthetic fibre for bullet proof protection
Kevlar is a high-strength, lightweight synthetic fiber that is used in a variety of applications, including bulletproof vests. Kevlar is made from poly-paraphenylene terephthalamide, which is a polymer that is produced from terephthalic acid and p-phenylene diamine. Kevlar has a high tensile strength, which means that it can withstand a great deal of force before breaking. It is also very resistant to heat and chemicals. These properties make Kevlar ideal for use in bulletproof vests.
When a bullet hits a Kevlar vest, the fibers of the vest absorb the energy of the bullet. The fibers are arranged in a way that allows them to interlock and trap the bullet. This prevents the bullet from penetrating the vest and injuring the wearer. The number of layers of Kevlar in a vest will determine the level of protection that it provides. A vest with more layers will be able to stop a higher-powered bullet.
Kevlar bulletproof vests are very effective at stopping bullets. However, they are not 100% effective. In some cases, a bullet may be able to penetrate a Kevlar vest. This is more likely to happen if the bullet is powerful or if it hits the vest at a certain angle. Kevlar vests are also not effective against knives or other sharp objects.
Despite their limitations, Kevlar bulletproof vests are an important safety device for law enforcement officers, military personnel, and other individuals who are at risk of being shot. They can help to save lives and prevent serious injuries.
In addition to bulletproof vests, Kevlar is also used in a variety of other applications. It is used in body armor, helmets, gloves, and other protective gear. Kevlar is also used in high-performance tires, racing sails, and other applications where strength and lightweight are important.
Kevlar is a versatile material with a wide range of applications. It is a valuable tool for protecting people and property.
Here are some additional benefits of using Kevlar in bulletproof jackets:
►Kevlar is lightweight and comfortable to wear. This makes it ideal for use in situations where the wearer needs to be able to move freely, such as law enforcement officers and military personnel.
►Kevlar is durable and can withstand repeated use. This makes it a cost-effective investment for organizations that need to provide their employees with body armor.
►Kevlar is available in a variety of colors and styles. This allows organizations to choose a vest that is appropriate for their needs and the needs of their employees.
Overall, Kevlar is an excellent material for use in bulletproof jackets. It is strong, lightweight, durable, and available in a variety of colors and styles. Kevlar bulletproof jackets can provide a high level of protection for law enforcement officers, military personnel, and other individuals who are at risk of being shot.

UP: Misled by GPS navigation, car falls into river from partially constructed bridge, 3 dead
Bareilly (UP), Nov 24: Three people died when their car fell into the Ramganga river from a partially constructed bridge here on Sunday, police said, adding that they suspect the driver was misled by its navigation system into taking the unsafe route.
The accident occurred around 10 am on the Khalpur-Dataganj road when the victims were travelling from Bareilly to Dataganj in the Badaun district, they said.
"Earlier this year, floods had caused the front portion of the bridge to collapse into the river, but this change had not been updated in the system," Circle Officer Ashutosh Shivam said.
The driver was using a navigation system and did not realise that the bridge was unsafe, driving the car off the damaged section, the police said.
There were no safety barriers or warning signs on the approach to the damaged bridge, leading to the fatal accident, Shivam said.
Upon receiving information, police teams from Faridpur, Bareilly and Dataganj police station rushed to the spot. They recovered the vehicle and the bodies from the river, Shivam added.
The circle officer said that bodies had been sent for post-mortem. Further investigation into the matter is underway.
