NationMaster - Encyclopedia: Chobham armour Although the exact composition of Chobham armour remains a secret, it appears to be a composite armour of ceramic tiles within a matrix that is layered between steel armour plating, a combination that is excellent at defeating high explosive anti-tank (HEAT) rounds. Composite armour is a type of vehicle armour consisting of layers of different material such as metals, plastics, ceramics or air. Composite materials (or composites for short) are engineered materials made from two or more constituent materials with significantly different physical or chemical properties and which remain separate and distinct within the finished structure. www.nationmaster.com /encyclopedia/Chobham-armour   (0 words)

Composite armour - Definition, explanation Composite armour is a type of armour consisting of layers of different material such as metals, plastics, ceramics or air. Most composite armours are lighter than their all-metal equivalent, but instead occupy a larger volume for the same resistance to penetration. It also carried an applique armour pack which is composed of a frontal steel plate about 60mm thick backed by an insert of three layers of inert interlayer reactive armour, composed of steel plates and penapolyurethane filler. www.calsky.com /lexikon/en/txt/c/co/composite_armour.php   (0 words)

Combined active and passive armor system - Patent 4869152 A composite armour system according to claim 3 wherein the resilient material is bonded to a rear face of the homogeneous metal armour plate. The traditional form of armour is of course in the form of a homogeneous metal plate such as armour steel or lighter aluminium alloys developed for use as armour plate. Reactive armour can provide increased effectiveness on a weight for weight basis against some attacking weapons, but can be difficult to fix to the surface of the installation or vehicle to be protected, and especially to do so whilst ensuring that a single hit does not detonate the whole area of reactive armour. www.freepatentsonline.com /4869152.html   (0 words)

Bambooweb: Composite armour Composite armour is a type of armour consisting of layers of different material such as metals, plastics, ceramics or air. Most composite armours are lighter than their all-metal equivalent, but instead occupy a larger volume for the same resistance to penetration. It is possible to design a composite armour both stronger, lighter and less voluminous than traditional armour, but the cost is often prohibitively high, restricting its use to especially vulnerable parts of a vehicle. www.bambooweb.com /articles/c/o/Composite_armour.html   (654 words)

CRAIG International Ballistics - How Body Armour Works Covert armour is worn under the clothing and gives the wearer an element of surprise, as well as protection when attacked. Tactical armour is worn in a situation where surprise is lost and the wearer needs a form of protection which may also have other practical functions; camouflage, load carrying or identification; e.g. The choice of colour, the style of the armour and the amount that is worn can give a distinct ascendancy to the wearer, as is evidenced by the appearance of a squad of fully protected riot police. www.ballistics.com.au /technical/howbodyarmourworks.php   (1197 words)

Composite material Summary The term composite is usually reserved for materials in which the distinct phases are separated on a scale larger than atomic, and in which the composite's mechanical properties have been significantly altered from those of the constituent materials. Composites tend to be developed when no single, homogeneous material can be found that had all of the desired characteristics for a given application. Composite materials (or composites for short) are engineered materials made from two or more constituent materials that remain separate and distinct on a macroscopic level while forming a single component. www.bookrags.com /Composite_material   (1909 words)

Composites Set New Limits - Science - RedOrbit Inspired originally by early developments in manufacturing composite armour plate, a dramatic new composite technology combines particulate and composite technologies, novel chemical formulations and ingenious low cost manufacturing techniques. He originally worked for Royal Ordnance, in the early days of its development of composite armour, which seems to have inspired his idea for 'Curon Roofing', rolls of composite material which can be unrolled on leaking roofs and which cure under ultra violet sunlight. Heat curable composites usually take around five weeks to achieve full strength, but are often taken out of their moulds after only a day or two for production cost reasons, leading to a risk of distortion while the cure continues out of the mould. www.redorbit.com /news/science/401183/composites_set_new_limits/index.html?source=r_science   (1068 words)

Compositions based on ceramics The armour from light ceramics and a composite based on high-strength materials intended for different branches of the armed forces, money collection service, special-purpose services, guards, etc. High protective characteristics are obtained owing to the maximum advantageous combination of properties of ceramics and organoplastics: bullet energy is suppressed at the expense of high specific impact resistance of ceramics and also at the expense of sliding and tension of organoplastic reinforcing fibers Composite ceramic armour is produced in the form of: www.technologiya.ru /tech/ceramicse/t0601.html   (227 words)

Protection Against Secondary Fragmentation From AP Mines Based on Natural Fibre Composites, by Paul Wambua, Marc ...   (Site not responding. Last check: ) The composite samples were processed by compressing the stacking in a compression moulding press at a pressure of 6.4 bar (0.64 MPa) on the material at 190 C for 15 minutes. The natural fibre composite panels and composite steel hybrid structures were clamped on a mild steel stand placed 10 meters (10.94 yards) from the weapon. The explosives were placed in the ground at a distance of 30 and 50 cm (50 cm only for plain composites) from the target and covered with different kinds of projectiles, such as stones, to increase the amount of secondary fragmentation and to simulate demining accidents. maic.jmu.edu /JOURNAL/9.1/RD/wambua/wambua.htm   (2446 words)

Anti-tank firepower The development in armour protection that has taken place in recent years and especially during the 90s has raised serious questions about the effectiveness of many existing anti-tank guns and anti-tank guided weapons. Vulnerable to interference and with penetration capability that has difficulty keeping up with developments in armour protection is symptomatic of a weakness that calls for a remedy. But with the introduction of supplementary armour, explosive reactive armour (ERA), inert reactive armour (IRA), multi-layer armour and other forms of special armour, it has become doubtful whether man-portable, medium- range, anti-tank weapons have the capacity to penetrate the protecting armour with enough residual (behind armour) effect. www.global-defence.com /2000/pages/antitnk.html   (1249 words)

Armour Materials [Part 2] - CASR - Canadian American Strategic Review Disadvantages of fibres are that they usually require space with which to stretch and absorb energy in their molecular bonds, [1] and that the fibres – and the resins they are fused together with – are vulnerable to burning and other thermal effects. Under such conditions, the armour material undergoes a quasi phase state change from a solid to a liquid possessing few of the mechanical properties of the original armour. Composite armours using variations on existing materials can offer resistances to projectiles comparable to steel (in the range of 30-35% of the weight). www.sfu.ca /~casr/id-rea2-2.htm   (970 words)

Armour Materials [Part 1] - CASR - Canadian American Strategic Review Existing armour materials are near the limits of their physical potential, and there is little prospect of some new, or improved, super-armour appearing. Steel armour has been the principle means of protection since the mechanization of the military because it has been the most cost efficient and effective material to use. Titanium is perhaps the strongest metal per mass for armour applications (at roughly 150-180% the toughness of steel) and in some specific matrix forms containing macro-molecular carbide pits can be close to four times as mass-efficient as a conventional steel armour. www.sfu.ca /casr/id-rea2-1.htm   (896 words)

BBC - h2g2 - Warheads Armoured vehicles are designed to protect their occupants and their operation from damage. Designers of armour have developed the ability to harden only the outer face of an armoured plate, with the potential of shattering the incoming projectile while not compromising the overall ductility of the armour. SFF projectiles are significantly affected by sloped armour and spacing, and somewhat less affected by face-hardening and composite armour. www.bbc.co.uk /dna/hub/A593499   (2563 words)

Iraq-bound vehicles without full defences - Iraq - www.theage.com.au Nearly half of the armoured vehicles supposed to protect 450 Australian troops in southern Iraq will not be fitted with full internal armoured linings before being deployed. Despite Government claims that 44 light armoured vehicles being sent to Iraq in less than two months will be fully refitted and protected, senior military sources have confirmed that close to half of them are scheduled to be fitted with protective curtains rather than the more effective linings. The composite armour "spall" liners are fitted to Australian vehicles already on patrol in Baghdad and were credited with helping save troops when a roadside bomb exploded beside one in October. www.theage.com.au /news/Iraq/Iraqbound-vehicles-without-full-defences/2005/03/01/1109546868239.html   (521 words)

Scanfiver Composites :: Light weight armour, advanced fibre composites, ballistic protection Depending on the required level of protection, the composite panels can be used either alone or combined with ceramics or ballistic steel (which is extremely hard) to reach very high levels of protection. A correctly manufactured composite panel can absorb very high impact loads and can defeat heavy pistol rounds at an aerial density (kg/sqm.) which is lower than if the same level of protection had to be reached with a steel plate. By high levels of protection the composite panel is normally combined with a strike surface based on either ceramics or ballistic steel (which is extremely hard). www.sovereign-publications.com /scanfiber.htm   (441 words)

Strategic Affairs - Technology The use of composites in military vehicles is predominantly driven by the material's ability to reduce hull and armour weight due to the increased weight efficiency of composite materials and by eliminating the need for separate composite spall liner. Although the tank's composite body is tough enough to withstand a range of ammunition, heavier weaponry could be countered by extra protective layers, such as ceramic cladding, fitted after delivery to a war zone. The tank's composite armour design is said to reduce "behind-the-armour'' damage inside the vehicle by absorbing the impact of ballistics, making the tank less susceptible to shrapnel. www.stratmag.com /issue2Aug-1/page03.htm   (833 words)

IADA Car Wars Compendium Errata Sheet Rubber armour may be used as a layer in composite armour, with metal and plastic. If a vehicle with rubber/plastic composite armour catches fire, the one point of fire damage each turn is taken from the innermost layer of armour. A volatile component armoured weapon will not cause a vehicle to explode as long as it is component armoured, however component armour provides no such protection against gas engines exploding. www.serv.net /~owenmp/iada/cwc.html   (3068 words)
