Second Chance (body Armor)
Second Chance is an American body armor manufacturing company that was the first firm to use kevlar for body armor. The company was founded in the early 1970s by former U.S. Marine and pizza delivery owner/driver Richard Davis. Davis developed the idea of a bulletproof vest after shooting three armed robbers in self-defense during a delivery. This incident was later documented in a 1995 book written by firearms instructor Massad Ayoob called ''The Ayoob Files: The Book''. Davis started his company out of his garage. In early sales demonstrations, he would put on one of his vests and then shoot himself, usually with a firearm provided by whatever agency he was demonstrating for. In 1998, Second Chance introduced Zylon-based body armor (bullet-resistant vests), as a lightweight alternative to kevlar. The Zylon material used in the vests was supplied by Japan-based Toyobo. In June 2005, the National Institute of Justice, the United States government agency responsible for develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulletproof Vest
A bulletproof vest, also known as a ballistic vest or a bullet-resistant vest, is an item of body armor that helps absorb the impact and reduce or stop penetration to the torso from firearm-fired projectiles and fragmentation from explosions. The vest may come in a soft form, as worn by many police officers, prison guards, security guards, and some private citizens, used to protect against stabbing attacks or light projectiles, using metallic or para-aramid components. Soldiers, police tactical units, marines, and special operations forces wear hard armors, either in conjunction with soft armor or alone, to protect against rifle ammunition or fragmentation. History Early modern era In 1538, Francesco Maria della Rovere commissioned Filippo Negroli to create a bulletproof vest. In 1561, Maximilian II, Holy Roman Emperor is recorded as testing his armor against gun-fire. Similarly, in 1590 Sir Henry Lee expected his Greenwich armor to be "pistol proof". Its actual effectiveness ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kevlar
Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components. Kevlar has many applications, ranging from bicycle tires and racing sails to bulletproof vests, all due to its high tensile strength-to-weight ratio; by this measure it is five times stronger than steel. It is also used to make modern marching drumheads that withstand high impact; and for mooring lines and other underwater applications. A similar fiber called Twaron with the same chemical structure was developed by Akzo in the 1970s; commercial production started in 1986, and Twaron is now manufactured by Teijin.

United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States. The Marine Corps has been part of the U.S. Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers. The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia as ...

Pizza Delivery
Pizza delivery is a service in which a pizzeria or pizza chain delivers a pizza to a customer. An order is typically made either by telephone, or over the internet, in which the customer can request pizza type and size, and other items to be delivered with it, commonly including soft drinks. Pizzas may be delivered in cardboard pizza boxes or delivery bags, and deliveries are made with either an automobile, motorized scooter, or bicycle. Customers can, depending on the provider, choose to pay online, or in person, with cash, credit card, debit card or other means. A delivery fee is sometimes charged, although free delivery is also common. Ordering Ordering pizza for delivery usually involves contacting a local pizza restaurant or chain by telephone or online. Online ordering is available in many countries, where some pizza chains offer online menus and ordering. The pizza delivery industry has kept pace with technological developments since the 1980s beginning with the ris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zylon
Zylon (IUPAC name: poly(''p''-phenylene-2,6-benzobisoxazole)) is a trademarked name for a range of thermoset liquid-crystalline polyoxazole. This synthetic polymer material was invented and developed by SRI International in the 1980s and manufactured by Toyobo. In generic usage, the fiber is referred to as PBO. Zylon has 5.8 GPa of tensile strength, which is 1.6 times that of Kevlar. Additionally Zylon has a high Young's modulus of 270 GPa, meaning that it is stiffer than steel. Like Kevlar, Zylon is used in a number of applications that require very high strength with excellent thermal stability. Tennis racquets, table-tennis blades, snowboards, various medical applications, and some of the Martian rovers are some of the better-known instances. Usage Body armor Zylon gained wide use in U.S. police officers body armor protection in 1998 with its introduction by Second Chance Body Armor, Inc. in its "Ultima" and "Ultimax" protective vests.

Armour (British English) or armor (American English; see spelling differences) is a covering used to protect an object, individual, or vehicle from physical injury or damage, especially direct contact weapons or projectiles during combat, or from a potentially dangerous environment or activity (e.g. cycling, construction sites, etc.). Personal armour is used to protect soldiers and war animals. Vehicle armour is used on warships, armoured fighting vehicles, and some mostly ground attack combat aircraft. A second use of the term ''armour'' describes armoured forces, armoured weapons, and their role in combat. After the development of armoured warfare, tanks and mechanised infantry and their combat formations came to be referred to collectively as "armour". Etymology The word "armour" began to appear in the Middle Ages as a derivative of Old French. It is dated from 1297 as a "mail, defensive covering worn in combat".
