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.

Canadian report finds 'no definitive link' between Nijjar killing and India
Ottawa, Jan 29 (PTI): A Canada commission report has said that "no definitive link" with a "foreign state" in the killing of Canadian Sikh activist Hardeep Singh Nijjar was "proven", smashing Canadian Prime Minister Justin Trudeau’s allegations that accused the involvement of Indian agents in the killing.
In September 2023, Trudeau said Canada had credible evidence that agents of the Indian government were involved in the murder of Nijjar in British Columbia in June 2023.
The report titled "Public Inquiry Into Foreign Interference in Federal Electoral Processes and Democratic Institutions' was released on Tuesday.
In the report commissioner Marie-Josee Hogue said "Disinformation is used as a retaliatory tactic to punish decisions that run contrary to a state's interests."
The report has suggested India spread disinformation on the killing of Nijjar.
"This may have been the case with a disinformation campaign that followed the Prime Minister's announcement regarding suspected Indian involvement in the killing of Hardeep Singh Nijjar (though again no definitive link to a foreign state could be proven)," the report said.
Nijjar was gunned down in Surrey, British Columbia, in June 2023.
The 123-page report also talked of expelling six Indian diplomats.
"In October 2024, Canada expelled six Indian diplomats and consular officials in reaction to a targeted campaign against Canadian citizens by agents linked to the Government of India," it said.
However, India expelled six Canadian diplomats and announced the withdrawal of its high commissioner.
The relations between India and Canada came under severe strain following Prime Minister Trudeau's allegations in September last year of the "potential" involvement of Indian agents in the killing of Nijjar.
New Delhi had rejected Trudeau's charges as "absurd".
India has repeatedly criticised Trudeau's government for being soft on supporters of the Khalistan movement who live in Canada. The Khalistan movement is banned in India but has support among the Sikh diaspora, particularly in Canada.
On Tuesday, India strongly rejected "insinuations" made against it in the report by a Canadian commission that investigated allegations that certain foreign governments were meddling in Canada's elections.
In a strong reaction, the MEA in New Delhi said it rejects the report's "insinuations" on India.
It is in fact Canada which has been "consistently interfering" in India's internal affairs, it said.
