U.S. Army Wants To Make Sniper Uniforms Out Of Hemp

 Army soldiers aren’t allowed to use hemp-derived CBD even if it's federally legal—but the military branch is now asking for information about using hemp yarn in uniforms to help camouflage snipers.

In a request for information (RFI) posted last week, the Army said that it’s interested in exploring alternative materials to improve uniforms used by snipers to hide from enemy combatants in close proximity. Hemp and jute are among the materials that it thinks could support the “Operational Clothing and Individual for the Improved Ghillie System (IGS).”

“Interest is specifically in a yarn/twine/thread used to break up the Snipers outline made from Jute, Hemp or similar natural fiber,” the notice says.

The Army’s Product Manager Soldier Clothing and Individual Equipment division is “seeking approximately a 48 lb Jute Count, 3 ply, Jute, Hemp or similar natural fiber, yarn/twine in a natural color,” it continues. “The current demand for the Jute/Hemp yarn is 400,000 yards.”

“The IGS is a new and improved Sniper concealment system developed to meet the concealment needs of the Sniper community. The IGS shall have amendable camouflage materials (e.g. jute, hemp, or similar natural fiber) that can be used to change the appearance of the sniper. The IGS Jute, Hemp, or other natural fiber will help conceal the Sniper and Scout during missions allowing them to remain undetected within close proximity of the enemy forces.”

Hemp was federally legalized under the 2018 Farm Bill. And while many have come to associate the crop with its derivatives like CBD oil, there’s growing interest in its other industrial applications, especially given its unique durability, versatility, and low environmental impact. Businesses have been marketing everything from hemp fabric in clothing to hemp concrete for buildings.

Now the Army wants to see whether the crop has the potential to better camouflage its snipers. The RFI says that hemp yarn can be spun domestically or imported from other countries, unlike jute which needs to be spun in the U.S. even if the fiber comes from a foreign source.

“The material shall not present a health hazard to the Soldier and must show compatibility with prolonged, direct skin contact,” it says. Also, the material cannot “add a significant amount of weight” to the uniforms. Responses to the RFI are due by July 27.

House Appropriations Committee has also recently identified the potential of the cannabis crop as a cost-effective alternative to plastics, including language in three recent spending bill reports that encourage research into using domestically grown hemp to reduce dependence on plastic imported from China, for example.

Rep. Dave Joyce (R-OH), a co-chair of the Congressional Cannabis Caucus and member of the Appropriations Committee, is spearheading that initiative.

Composite Armour Tank

 📢It's Story-Time!📢

The first mass-produced tank with composite armour!

Composite armour is a type of vehicle armour consisting of layers of different materials 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 composite armour 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. Its primary purpose is to help defeat high-explosive anti-tank (HEAT) projectiles.

The Soviet tank T-64 is deemed to be the first mass-produced tank to have widespread use of composite armour technology. Its protection included a 3-layer composite armour (K formula), with a thickness between 450 and 20 mm:

Front: 120 mm steel, 105 mm fibreglass, 40 mm steel.

Sides: 80 mm steel.

Front of the turret: 150 mm steel, 150 mm fibreglass, 40 mm steel.

Even though the original T-64 concept dates back to the early 1960s, many countries still use its modernized versions: T-64s have been used by both Russian-backed separatists and Ukraine during the 2022 Russian invasion of Ukraine.

Diab was awarded the 100% thermoplastic and recyclable panel for cabin interiors at JEC World 2022

Diab received the JEC Composites Innovation Award for the 100% Thermoplastic and Recyclable Panel for Cabin interiors. The panel is 100% recyclable, includes recycled content from production waste, and is consequently 100% waste-free. Being recyclable and reusable, it offers the Aerospace industry a vital step toward a circular economy.

Diab’s sustainable panel solution for cabin interiors takes advantage of the performance of the structural foam core Divinycell F and combines it with thermoplastic skins. Using only materials already tested and qualified by Aerospace OEM, the panel is fully compliant with all requirements within the industry, yet 100% recyclable.

Diab also created a new innovative manufacturing process that saves up to 20% of the cost, up to 10% of weight, and offers higher mechanical and fire resistance behavior than current Honeycomb core and Phenolic resin/Glass fibre solutions.

“At the start of the project, we decided to think out of the box and push the limit of existing materials and processes”, says Aurelien Lafforgue, Market Segment Manager Aerospace & Industry at Diab. “We wanted to simplify the manufacturing process as much as possible with a single step process, with the panel ready to use out of the mould as the ultimate target.”

Consequently, Diab decided to avoid using an adhesive film and instead welded together skins and core to create adhesive properties much higher than the current solution with Phenolic resin. The result is mechanical properties that are fully compliant with cabin interior applications.

In addition, Diab decided to use a new generation of coating systems developed for the cabin interior market that can effectively be ‘welded’ to the panel as it is molded in a single, one-step process using induction heating. This method takes minutes rather than hours, which is the case when using multiple layers.

The shaped and decorated parts presented during JEC Show (the product picture above) have been produced in one single-step process in partnership with the company Aviacomp.

Diab, together with their partners AkzoNobel, Roctool, and RESCOLL, shape the future of cabin interiors.
