EXPLOSIVES TEXTILES

welcome back to war! Today's subject as I already said yesterday explosive textiles:
"Rayon is a fiber produced from recycled wood pulp or bamboo cellulose processed by a combination of many chemicals involving carbon disulphide, sulfuric acid, ammonia, acetone and caustic soda to bear regular washing and constant wearing"
"Acrylic’s manufacturing process, if not properly monitored can result in an explosion. Acrylic fibers are highly inflammable and not easy recyclable nor biodegradable in the environment. "

ITS NEED AN ORGANIC SOLVENT:
2-Butanol, or sec-butanol, is an organic compound with formula CH₃CH(OH)CH₂CH₃. This secondary alcohol is a flammable, colorless liquid that is soluble in 3 parts water and completely miscible with polar organic solvents such as ethers and other alcohols. It is produced on a large scale, primarily as a precursor to the industrial solvent methyl ethyl ketone. 2-Butanol is chiral and thus can be obtained as either of two stereoisomers designated as (R)-(−)-2-butanol and (S)-(+)-2-butanol. It is normally found as an equal mixture of the two stereoisomers — a racemic mixture

RF Safe-Stop Shuts Down Car Engines With Radio Pulse

An anonymous reader writes with news of a device built by a company in the U.K. which uses pulses of electromagnetic energy to disrupt the electronic systems of modern cars, causing them to shut down and cut the engine. Here's a description of how it works: "At one end of a disused runway, E2V assembled a varied collection of second-hand cars and motorbikes in order to test the prototype against a range of vehicles. In demonstrations seen by the BBC a car drove towards the device at about 15mph (24km/h). As the vehicle entered the range of the RF Safe-stop, its dashboard warning lights and dials behaved erratically, the engine stopped and the car rolled gently to a halt. Digital audio and video recording devices in the vehicle were also affected.''It's a small radar transmitter,' said Andy Wood, product manager for the machine. 'The RF [radio frequency] is pulsed from the unit just as it would be in radar, it couples into the wiring in the car and that disrupts and confuses the electronics in the car causing the engine to stall.'

Defense Distributed: Successful test fire of first 3D printed pistol (video)

Defense Distributed has released a video of the successful test firing by hand of their first complete 3D printed pistol, the "Liberator". The Liberator has only one metal part, the firing pin, made from a common nail. In the video, Cody Wilson is shown firing the pistol by hand, to dramatically illustrate his faith in the design. The Liberator is a single shot pistol in .380 (9X17) caliber. While firearms have been made in home workshops ever since they have been in existence, the ability to download computer files and have a computer controlled machine print all the parts to a functioning firearm has caught the public attention.  Dean Weingarten, Defense Distributed Distributor

NON DETECTABLE GLOCK 7

welcome back to war! Today's subject, ceramic guns non detectable! Ok, everybody knows here I've been trought the Glock 7, everybody wants to ge the hands on smile emoticon Now, we already have a 3D design for a Glock piece, but we didn't have teh right material, which the Glock 7 is made of, so here it is:

Making Cermet II Materials

What follows are some explanations of how to make advanced carbide.  These are pretty short explanations but they will give an idea of all that is possible. 

Obviously we use different techniques for different grades and applications.  We have compiled a great deal of infomation on Carbide and Advanced Materials in our Tool Tipping Index.  
How It Works 
Carbide wear is due to micro-fracturing, macro-fracturing, grain pull out, corrosion of the binder, adhesion between the carbide and the material being cut, and tribological functions which are similar to a naturally occurring electro-etching. 
Cermet II technology uses a variety of carbides such a titanium carbide, tungsten carbide, Tantalum carbide, Niobium carbide and others.  Steel is iron with a very small amount of carbide but it is very different than plain iron.  The addition of a very small amount of the right material can make a huge difference in carbide performance as well. 
Cermet II grades also use unique binder formulations.  Cobalt is a good binder material and is used in standard grades.  It was the first binder used and is still easiest to use.  However cobalt is pure metal and is subject to chemical attack.  Part of the secret of our Cermet II grades is to chemically alloy special binders with a proprietary metalloid which makes the cobalt binder non-reactive so it doesn’t corrode.  It also greatly strengthens the binder so grinds aren’t pulled out. 
Cermet II grades have special binder properties so that they behave more as a solid piece of material than as a cemented piece of material.  Think of a steel alloy as compared to concrete.  
Grain Size 
The most important reason for this widening of the spectrum of available WC grades is that, besides those variations achieved by cobalt contents and some carbide additives, the properties of WC-Co hardmetals such as hardness, toughness, strength, modulus of elasticity, abrasion resistance and thermal conductivity can be widely varied by means of the WC grain size. While the spectrum of available WC grain sizes ranged from 2.0 to 5.0 µm in the early days of the hardmetal industry in the mid 1920’s, the grain sizes of WC powders now used in hardmetals range from 0.15 µm to 50 µm, or even 150 µm for some very special applications.  
Grain Size 
The history of tungsten carbide powder metallurgy, and especially that of the hardmetal industry, is characterized by a steadily widening range of available grain sizes for processing in the industry; while, at the same time, the grain size distribution for each grade of WC powder became narrower and narrower. 
The most important reason for this widening of the spectrum of available WC grades is that, besides those variations achieved by cobalt contents and some carbide additives, the properties of WC-Co hardmetals such as hardness, toughness, strength, abrasion resistance and thermal conductivity can be widely varied by means of the WC grain size. While the spectrum of available WC grain sizes ranged from 2.0 to 5.0 µm in the early days of the hardmetal industry in the mid 1920’s, the grain sizes of WC powders now used in hardmetals range from 0.5 µm to 50 µm, or even 150 µm for some very special applications. 
The first submicron hardmetals were launched on the market in the late 1970s and, since this time, the micro-structures of such hardmetals have become finer and finer. The main interest in hardmetals with such finer grain sizes derives from the understanding that hardness and wear resistance increase with decreasing WC grain size. 
With optimum grade selection, sub micron grain size tungsten carbide can be sharpened to a razor edge without the inherent brittleness frequently associated with conventional carbide. Although not as shock-resistant as steel, carbide is extremely wear-resistant, with hardness equivalent to Rc 75-80. Blade life of at least 50X conventional blade steels can be expected if chipping and breakage is avoided. 
Advanced Manufacturing Techniques 
Better, cleaner powder has been achieved through improved solvent extraction in tungsten chemistry as well as new techniques in hydrogen reduction and carburization to improve the purity and uniformity of tungsten and tungsten carbide powder. 
New powder milling, spray drying and sintering techniques have resulted in improved hardmetal properties and performance. Notably, the continuous improvement of vacuum sintering technology and, starting from the late 1980’s, hot isostatic pressure sintering (SinterHIP) led to new standards in hardmetal quality.

The design for thermonuclear ignition that Klaus Fuchs turned over to his Soviet control in March 1948. The detonator (box) on the left represents a gun-type fission bomb consisting of a projectile and target of highly enriched uranium (71 kg of 70% pure U235), which when joined form a supercritical mass and produce an explosive chain reaction. The projectile is carried forward by its momentum, striking the beryllium-oxide (BeO) capsule on the right, which contains a liquid 5...0:50 D–T mixture, compressing it by a factor of about 3, as represented by the outer circle. The radiation produced in the fission bomb heats up the BeO capsule, producing completely ionized BeO gas, which exerts pressure on the completely ionized D–T gas, compressing the capsule further to an overall factor of about 10, as represented by the inner circle.
The detonator is а fission bomb of the gun type. The active material is 71 kg of 40% pure U233 [sic].3 The plug (48.64 kg) sits in the projectile, which is shot bу the gun into the target, the remaining 22-24 kg sits in the target. The tamper is ВеО. The fission gadget has аn efficiency of 5% (calculated). The tamper, which is transparent for the radiation from the fission bomb, is surrounded bу an opaque shell which retains the radiation in the tamper and also shields the booster and main charge against radiation. […]
The primer contains 346 gm of liquid D-Т in 50:50 mixture, situated in the tamper. It is first compressed bу the projectile to 3-fold density. This precompression may not bе necessary. As the tamper and primer аге heated bу the radiation, the primer is further compressed, possibly to 10-fold density. (Radiation transport equalises the temperature in primer and tamper, and gives therefore rise to а pressure differential.) The compression opens the “gap” for the ignition of the primer. The primer is likely to have а very high efficiency (~80 %) of energy release.
The booster beyond the radiation shield contains D with about 4% Т. It is ignited bу the neutrons from the primer. Beyond the booster is the main charge of pure D, а cylinder of about 30 сm radius to contain the neutrons and arbitrary length.

So what’s happening here is that the big piece of uranium is being shot against another piece
