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.

Kodagu: Five arrested for murder of coffee estate owner
Madikeri: Kodagu police have arrested five men in connection with the murder of coffee estate owner Pradeep Koili, whose body was found at his residence in Kongana village on April 23. Among those arrested is NS Anil, a short film director and actor, who has been identified as the main accused in the case.
Pradeep Koili, a native of Kannur in Kerala, was living alone at his plantation located under the B Shettigeri Gram Panchayat limits. He was found dead at his home last week, allegedly strangled using a nylon rope. The murder, which shocked the local community, triggered an intensive investigation led by a 12-member police team.
Addressing reporters on Saturday, Kodagu Superintendent of Police Ramarajan said that the five arrested individuals have been remanded to judicial custody. The accused have been identified as NS Anil (25) from Mugutageri village, Harish TS (29) from Nalluru village in Ponnampet taluk, Deepak (21) from Abburukatte village, Stefen D'Souza (26) from Nerugalale village, and Karthik HM (27) from Hithalamakki village in Somwarpet taluk.
According to police, Anil, the primary suspect, had been under pressure after a marriage proposal fell through. During the marriage discussions, the prospective bride’s family is said to have expressed reservations about Anil due to his lack of employment and assets. Police believe this setback may have motivated him to plot the murder, allegedly in a bid to acquire wealth quickly.
SP Ramarajan also revealed that Anil had a history of fraud. He had previously duped several residents in Bengaluru, Hassan, and Ponnampet by falsely claiming he could help locate hidden treasure on their properties. Similar fraudulent attempts were also reported in areas like Thithimathi, Konanakatte, and nearby villages.
In the present case, Anil had reportedly approached Pradeep Koili pretending to represent foreign buyers interested in purchasing the estate. He is said to have paid the victim Rs 1 lakh as advance to gain his trust.
CCTV footage from the area showed that the accused had attempted to cover up the crime by burying Koili’s body and trying to destroy surveillance cameras. During the investigation, police recovered Rs 13 lakh allegedly stolen from Koili’s house. They also seized two motorcycles, three mobile phones, and documents related to the estate property.
