US military says it’s considering a new generation of non-fibrous alloy materials
The US military is considering a range of new non-fabricated materials, which could include some of the strongest non-toxic, non-metallic elements on the planet, the Pentagon has said.
Non-fiberglass composite materials could be a “great way” to reduce the size and weight of weapons systems, the service has said in a letter to the US Senate.
The military said in its letter to Congress that “any one of the proposed materials would be strong enough to meet the physical and environmental demands of the modern combatant”.
A range of materials have already been suggested, including magnesium aluminum and aluminum alloys.
But some military experts say the use of such materials could cause problems in future missions due to the high temperatures and extreme temperatures that would be required to melt such materials.
“We are certainly open to all possibilities,” said John Ruggiero, a professor at the University of Virginia’s Institute of Aerospace Engineering.
But he added that there was a huge potential problem with making a lightweight, nonfibre glass material, which would require a lot of heat and energy.
(Reuters)”We need to find something that’s a little more lightweight, but it’s still durable,” he said.
“If we can’t find it, we need to make something else.
We have to find a material that is lightweight but has a high melting point, and that’s the problem with the non-carbon fiber materials.”
A few non-fluffy, nonmetal components of a weapon’s armour would also be critical, because they are the materials that would make up the body armour that is used by soldiers.
“We’ve been trying to find the strongest material that would work as an armour for decades,” said Mark Pendergast, professor of civil and environmental engineering at the US Naval Postgraduate School.
“(But) that is not going to be a silver bullet, and we need a lot more advanced materials to make that happen.”
A new generation non-metal materials could reduce the amount of time it takes for weapons to break downA new research team, led by US Defence Secretary Chuck Hagel, is working to develop lightweight non-machined materials that are lighter, more flexible and stronger than existing materials, and more effective in the battle against the improvised explosive devices, or IEDs, that the US military has been fighting since the 9/11 attacks.
“The key question is: how do you make something that is lighter, stronger, and flexible?” said Mark Czeisler, professor and director of the Department of Physics and Astronomy at the State University of New York at Stony Brook.
One possibility being considered is using a non-crystalline form of magnesium aluminum alloy, which has previously been used in the development of the world’s strongest lightweight glass.
The material is a type of aluminum alloy with a superhard core, known as the superhydrophobic phase, which makes it highly resistant to heat and corrosive elements.
Manganese and magnesium, which are also common elements in glass, could also be used.
A second possibility being explored is the use.
of high-strength aluminum, a metal used in aircraft parts.
That could be made of titanium, a super-strong alloy that is often used in military and aerospace systems.
“A combination of all of these materials will make it possible to make things that are very strong and lightweight,” Mr Ruggie said.
Some experts also want to use the nonferrous aluminum found in plastic, such as those found in smartphones, to make lightweight components.
However, it would be very expensive and difficult to use this type of material in a weapon, because it has an extremely high melting temperature.
“It is not a cheap or easy material to make, and it’s going to take a long time to get that technology going,” said Robert Smith, director of engineering for aerospace firm R&D Institute for Aerospace Engineering (R&DIFE).
“The non-hydrophilic phase of the aluminum is the weakest part of the alloy and is where the melting is done.”
A research team at the Naval Research Laboratory (NRL) in Woods Hole, Massachusetts, has developed a superhydrogenic non-fluidic process for making ultra-strength non-magnesium aluminum alloy from a polymer called polyethylene.
“This material is made up of superhydroxyl groups,” said NRL researcher Christopher Linn.
“These superhydrogens have an electric charge that when added to water react with a ferric ion to form a superoxide state.”
The process produces the material at room temperature in less than a minute.
Linn and his team are working to refine the process to produce a more powerful alloy that can withstand
