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.

New Delhi(PTI): Climate activist Sonam Wangchuk and several others from Ladakh paid tributes to Mahatma Gandhi at his memorial Rajghat on Wednesday evening and later said they have been released from police detention and ended their fast.
The group gave a memorandum to the government listing their demands, and have been assured of a meeting with top leadership soon, Wangchuk said, adding they have ended their fast.
"We have given a memorandum to the government to protect Ladakh under such constitutional provisions so that its ecology can be preserved, in this case it is the Sixth Schedule, which gives locals the right to govern and manage the resources," Wangchuk told media after visiting Mahatma Gandhi's memorial.
"Locals should be empowered in the Himalayas because they can best preserve it," he said.
"In the coming days, we will meet the prime minister, president or home minister, this is the assurance we have been given by the home ministry," he said.
"We have demanded a democratic set-up for Ladakh, and the Sixth Schedule is also a part of it. We have been assured that we will meet top leadership, and the date of meeting will be confirmed in a couple of days," Wangchuk said.
A senior police officer confirmed that Wangchuk and all other 'padayatris' were released in the evening.
"They were allowed to go after an assurance from them of not gathering or holding any yatra as Section 163 is imposed in central parts of the national capital," the officer said.
Wangchuk was kept at the Bawana police station while other 'padayatris' were at three other police stations at Delhi-Haryana border.
All were escorted in buses by police personnel till Rajghat at about 9.30 pm and later, Wangchuk and all others 'padayatris' were allowed to go.
Police sources said Wangchuk might stay in Delhi for a few more days to seek meeting with the government.
Wangchuk said they have been assured that talks with the representatives of the Leh Apex Body and Kargil Democratic Alliance will resume within 15 days.
Wangchuk was leading the 'Delhi Chalo Padyatra', which began from Leh a month ago. Around 170 people from Ladakh, who were marching to Delhi demanding safeguards under the Sixth Schedule of the Constitution for the Union Territory among other things, were detained on Monday night at Delhi's Singhu border, and were taken to different police stations where they went on a hunger strike.
The march was organised by the Leh Apex Body (LAB), which along with the Kargil Democratic Alliance (KDA), has been spearheading an agitation for the past four years to demand statehood for Ladakh, seek its inclusion under the Sixth Schedule of the Constitution, early recruitment process along with a public service commission for Ladakh and separate Lok Sabha seats for Leh and Kargil districts.
Delhi Police had detained them citing the imposition of section 163 (which was earlier section 144 of CrPC) of Bharatiya Nagarik Suraksha Sanhita in the districts of New Delhi, North and Central and all police stations jurisdiction sharing the borders with other states.
